Codonopsis pilosula Lipophilic Extract-Loaded Thermosensitive Nanogel Attenuates Skin Photoaging by Inhibiting the FGFR/PI3K/AKT/mTOR Pathway

Jiangtao Zhou,Yuhui Ge,Ran Li,Zhuoyang Cheng,Jianping Gao,Bin Zheng

Background: Skin photoaging, primarily induced by chronic ultraviolet (UV) radiation exposure, is characterized by dryness, wrinkle formation, pigmentation abnormalities, and reduced skin elasticity, resulting from oxidative stress, inflammation, and degradation of the extracellular matrix. Codonopsis pilosula , a traditional food–medicine homologous plant, is recognized for its anti-aging properties. However, its lipophilic components (designated as CP-L) remain insufficiently explored. Methods: Herein, we developed a thermosensitive nanogel encapsulating CP-L-loaded transferosomes (CP-L nanogel) to enhance topical delivery and evaluated its effects in both a UV-induced photoaging mouse model and UVB-irradiated HaCaT keratinocytes. Results: In UV-induced mice, topical application of the nanogel markedly reduced skin wrinkling and epidermal hyperplasia, with epidermal thickness decreased by 83.2% compared to the model group ( p < 0.01), and restored skin elasticity and collagen deposition, as evidenced by a 35.5% increase in collagen area fraction ( p < 0.01). Correspondingly, in UVB-irradiated HaCaT cells, it significantly increased cell viability from 53.0 ± 9.6% to 89.4 ± 1.0% ( p < 0.01) and suppressed apoptosis from 30.1 ± 0.48% to 12.4 ± 0.66% ( p < 0.01). Furthermore, the CP-L nanogel consistently attenuated oxidative stress, with SOD, CAT, and GSH-Px activities increased by 73.1%, 188.1%, and 18.2%, respectively ( p < 0.01), and MDA levels reduced by 71.0% ( p < 0.01), while inflammatory responses were suppressed, as TNF-α, IL-1α, IL-1β, and IL-6 levels decreased by 28.3%, 22.6%, 12.8% and 31.9%, respectively ( p < 0.01). Mechanistically, transcriptomic and molecular analyses revealed that the nanogel potently inhibited the UV-induced activation of the FGFR/PI3K/AKT/mTOR/p70S6K signaling cascade at both transcriptional and protein levels, with the phosphorylation levels of FGFR, PI3K, AKT, mTOR, and p70S6K significantly reduced by 43.9%, 30.9%, 38.8%, 34.9%, and 57.3%, respectively ( p < 0.01). Molecular docking and dynamics simulations identified isofuranodienone and aromadendrene oxide-(2) as key constituents with high-affinity, stable binding to FGFR1 and AKT1. The cytoprotective effect of the nanogel was completely abolished by co-treatment with the FGFR inhibitor PD173074 , confirming functional reliance on this pathway. Enhanced cellular delivery of the formulation was directly demonstrated by flow cytometry, showing an approximately 1.8-fold increase in cellular uptake compared to the free drug ( p < 0.01). Conclusions: Collectively, these results demonstrated that the CP-L nanogel alleviated skin photoaging through a multi-faceted mechanism involving enhanced cellular delivery, potent antioxidant and anti-inflammatory activities, and specific inhibition of the FGFR/PI3K/AKT/mTOR signaling cascade, highlighting its potential as a multitargeted topical agent derived from an edible plant.

Epigallocatechin Gallate Attenuates CaOx Crystal-Induced Renal Tubular Injury to Inhibit CaOx Nephrolithiasis via GRP94/PI3K/AKT Signaling

Jian Wu,Minghui Liu,Meng Gao,Yongchao Li,Youjie Zhang,Liang Tang,Hao Yu,Zhangcheng Liao,Yu Cui,Feng Zeng,Hequn Chen,Zewu Zhu

Although tea consumption has been suggested to affect kidney stone formation, epidemiological evidence remains inconsistent, and the underlying molecular mechanisms are unclear. To assess the association between tea intake and kidney stone risk, we initially conducted a prospective cohort analysis of 481,393 participants from the UK Biobank and a 2-sample Mendelian randomization (MR) analysis. Our findings revealed that heavy tea drinkers (>5 cups/day) had a significantly reduced risk of kidney stones (hazard ratio: 0.79, 95% confidence interval [CI]: 0.72 to 0.86, P < 0.001), and MR analyses confirmed a causal association (inverse variance weighted OR: 0.45, 95% CI: 0.32 to 0.62, P < 0.001). We next explored the effect of epigallocatechin gallate (EGCG), the main bioactive component in tea, on calcium oxalate (CaOx) stone formation. EGCG was found to inhibit the glucose-regulated protein 94/phosphatidylinositol 3-kinase/protein kinase B (GRP94/PI3K/AKT) pathway in human proximal renal tubular epithelial cells, thereby attenuating CaOx crystal-induced oxidative stress and inflammation, and inhibiting crystal-cell adhesion. This finding aligned with the observation that the activated GRP94/PI3K/AKT pathway was positively associated with inflammation-related molecules in renal papillary tissues of CaOx stone formers. Moreover, to enhance renal targeting and therapeutic potential, we synthesized cell membrane-coated EGCG-loaded poly(lactic-co-glycolic acid) (TP-EGCG) nanoparticles, which enhanced renal EGCG delivery and substantially reduced CaOx crystal deposition in a mouse model of CaOx nephrolithiasis. In conclusion, tea consumption protects against kidney stone formation, an effect exerted by EGCG through the GRP94/PI3K/AKT axis, and our novel TP-EGCG nanoparticles show strong potential for targeted prevention and treatment.

Black Phosphorus Nanosheets Induce Ferroptosis in Oral Squamous Cell Carcinoma via PI3K-AKT-SREBP1 Signaling Pathway-Mediated Lipogenesis

Xianghuai Zheng,Yue Zou,Qinkai Xie,Hao Dong,Jiating Lin,Xianxian Zhuang,Ruoting Xian,Shaobing Li

Oral squamous cell carcinoma (OSCC) presents significant therapeutic challenges due to chemoresistance and limited treatment modalities. Black phosphorus nanosheets (BPNSs), a novel two-dimensional nanomaterial, have shown promising antitumor effects. However, their role in inducing ferroptosis in OSCC and the underlying mechanisms remain to be elucidated. In this study, BPNSs were prepared via liquid-phase exfoliation, and their effects on the OSCC CAL-27 cells were subsequently evaluated. In vitro, BPNSs dose-dependently inhibited CAL-27 cell proliferation, induced G2/M phase arrest, and triggered ferroptosis, indicated by increased intracellular Fe2+, ROS, and lipid peroxidation, along with decreased glutathione (GSH) levels and altered expression of ferroptosis-related proteins (ACSL4, NCOA4, and GPX4). These effects were attenuated by ferroptosis inhibitor ferrostatin-1. In vivo, BPNSs suppressed CAL-27 xenograft growth without systemic toxicity, with elevated tumor malondialdehyde (MDA) and Fe2+ confirming ferroptosis. Mechanistic studies indicated that BPNSs inhibited the PI3K-AKT pathway, leading to the downregulation of SREBP1. Overexpression of SREBP1 attenuated BPNS-induced ferroptosis, confirming its critical role. These findings suggest that BPNSs induce ferroptosis in OSCC via the PI3K-AKT-SREBP1 signaling pathway, providing a novel therapeutic strategy for OSCC treatment.

EXPRESS: Amino Acid Transporter SLC38A3 Mediates Bone Cancer Pain in Rats Via the PI3K/AKT/TRPV1 Signaling Pathway

Yu-Na Cheng,Ming-Zhu Zhang,Cui-Qing Xie,Zhi-Qi Li,You-Feng Ge,Zhao-Hui Jin,Zhi-Hua Luo,Chen-Yang Zheng,Liang Chen,dong fang,Chen-Guang Niu,Jin-Jin He

Bone cancer pain (BCP), one of the most intractable symptoms in patients with cancer, remains poorly understood and lacks effective therapeutic interventions. In this study, we employed an established rat model of BCP induced by intratibial injection of MRMT-1 mammary carcinoma cells. Transcriptomic profiling of the L4-L6 dorsal root ganglia (DRGs) revealed an upregulation of the amino acid transporter SLC38A3. This finding was further confirmed by time-dependent increases in both its mRNA and protein levels. Immunofluorescence co-localization indicated that SLC38A3 was expressed in NF200-, CGRP-, and IB4-positive neurons within the L4-L6 DRGs, and its expression was upregulated in the BCP model. Concomitantly, the transient receptor potential vanilloid 1 (TRPV1) expression in BCP rat DRGs was dynamically upregulated at both the mRNA and protein levels, aligning temporally with pain hypersensitivity. Lentivirus-mediated overexpression or knockdown of SLC38A3 in the DRGs led to a corresponding upregulation or downregulation of TRPV1-expression. Activation of the PI3K/AKT signaling pathway corresponds with BCP-related pain behaviors and expression patterns of SLC38A3 and TRPV1. Bexarotene alleviates BCP in rats by suppressing the aberrant overexpression of SLC38A3, thereby blocking the PI3K/AKT signaling pathway-mediated upregulation of TRPV1. These findings indicate that SLC38A3, through its downstream PI3K/AKT-TRPV1 axis, may serve as a potential molecular mechanism for analgesia in BCP.

Inhibition of Neuroinflammation by Costunolide Attenuates Hypoxic-Ischemic Brain Damage via the PI3K/AKT Pathway in Neonatal Rats

Hu Yingying,Qian Rengcheng,He Yifeng,Gao Qiqi,Wang Xun,Lin Huilin,Lin Wei,Fang Yu,Zhu Jianghu,Wang Xingyun,Nan Yan,Lin Zhenlang

Neonatal hypoxic-ischemic brain damage (HIBD) is a devastating disease for which no treatments that effectively mitigate severe neurological consequences exist. Recent studies have shown that costunolide (COS), a well-known bioactive sesquiterpene lactone, possesses potent anti-inflammatory and neuroprotective properties, but its efficacy in the context of HIBD remains unclear. Here, we investigated the neuroprotective effects of COS in both in vivo and in vitro models of hypoxic-ischemic (HI) brain injury. In vivo, we found that COS intervention following a HI event dramatically reduced the brain infarction volume, ameliorated the inflammatory response, promoted histological recovery, and improved the prognosis. To explore the underlying molecular mechanisms, we performed an in vitro study and reported that COS protected PC12 cells from oxygen‒glucose deprivation (OGD) insult by reducing the levels of inflammatory mediators. Furthermore, COS activated the PI3K/AKT signaling pathway to suppress NF-κB and inflammation. In contrast, the PI3K inhibitor LY294002 reversed these therapeutic benefits. Our findings reveal that COS is a promising neuroprotective agent and could be used to treat HIBD and other related brain injuries.

ROCK inhibition promotes axon and myelin regeneration via PI3K/Akt/GSK3β in a mouse sciatic nerve injury model

Shuang Dou,Zhijun Li,Boyao Zheng,Zhenyu Ren,Hai Wang,Qing Zuo,Fang Fang,Yuehong Zhuang

The present study investigates the molecular mechanisms of peripheral nerve regeneration by examining the ROCK/PI3K/Akt/GSK3β pathway's role in promoting morphological and functional recovery after peripheral nerve injury (PNI). Using a mouse sciatic nerve crush (SNC) injury model and a dorsal root ganglion (DRG) explant axotomy model, mice and DRG were divided the experimental (treated with DMSO) group, Y27632 group (treated with ROCK inhibitor Y27632), Y + LY group (treated with Y27632 + PI3K inhibitor LY294002), and Y + LY + SB group (treated with Y27632 + LY294002 + GSK3β inhibitor SB216763). Immunofluorescence was used to assess axon density, diameter, myelin thickness and Schwann cell proliferation, while retrograde tracing with cholera toxin subunit B evaluated peripheral-to-central reconnection. Behavioral tests measured functional recovery, and in DRG explants, axon regeneration length and growth cone size were quantified. Protein expression analysis of RhoA, ROCK, PI3K, Akt, GSK3β, and their phosphorylated forms was conducted on day 3 post-axotomy, both in vivo and in vitro . Additionally, RSC96 Schwann cell migration and proliferation were evaluated using scratch assays and EdU staining. Results showed that ROCK inhibition with Y27632 significantly enhanced axonal regeneration, growth cone expansion, retrograde transport, and reinnervation of acetylcholine receptors and Merkel cells, and promoted Schwann cell proliferation and RSC96 migration, leading to thicker myelin sheaths after SNC. These changes mitigated gastrocnemius muscle atrophy, improved muscle strength, gait, and thermal/tactile sensitivity. Co-treatment with LY294002 blocked these effects, but adding SB216763 restored them. Protein analysis indicated that ROCK inhibition increased phosphorylated PI3K, Akt and GSK3β, whereas PI3K inhibition reduced GSK3β phosphorylation. These findings suggested that ROCK inhibition promotes axon regeneration and remyelination after PNI by enhancing PI3K/Akt phosphorylation and suppressing GSK3β activity, highlighting the therapeutic potential of targeting the ROCK/PI3K/Akt/GSK3β pathway for peripheral nerve repair.

Silencing EIF3A ameliorates pulmonary arterial hypertension through HDAC1 and PTEN/PI3K/AKT pathway in vitro and in vivo

Hai-Tao Yang,Guan Wang,Peng-Cheng Zhu,Zhao-Yang Xiao

Pulmonary vascular remodeling caused by the excessive proliferation of pulmonary arterial smooth muscle cells (PASMCs) is the hallmark feature of pulmonary arterial hypertension (PAH). Eukaryotic initiation factor 3 subunit A (EIF3A) exhibited proliferative activity in multiple cell types. The present study investigated the role of EIF3A in the progression of PAH. A monocrotaline (MCT)-induced PAH rat model was constructed, and adeno-associated virus type 1 (AAV1) carrying EIF3A shRNA was intratracheally delivered to PAH rats to block EIF3A expression. PASMCs were isolated from rats and treated with PDGF-BB to simulate PASMC proliferation , and shRNA for EIF3 was conducted to investigate the mechanism behind the role of EIF3A in PASMC function in vitro . EIF3A expression was upregulated in pulmonary arteries, and EIF3A inhibition effectively improved pulmonary hypertension and right ventricular hypertrophy and suppressed MCT-induced vascular remodeling in vivo . In addition, we found that genetic knockdown of EIF3A reduced PDGF-triggered proliferation and arrested cell cycle, accompanied by downregulated proliferation-related protein expression in PASMCs. Mechanistically, the histone deacetylase 1 (HDAC1)-mediated PTEN/PI3K/AKT pathway was recognized as a primary mechanism in PAH progression. Silencing EIF3A decreased HDAC1 expression, and further inhibited the excessive proliferation of PASMCs by increasing the phosphatase and tension homolog (PTEN) expression and suppressing the AKT phosphorylation. Notably, HDAC1 expression reversed the effect of silencing EIF3A on PAH and PTEN/PI3K/AKT pathway. Collectively, silencing EIF3A improved PAH by decreasing PASMC proliferation through the HDAC1-mediated PTEN/PI3K/AKT pathway. These findings suggest that targeting EIF3A may represent a potential approach for the treatment of PAH.

DAB2 promotes pulmonary fibrosis and may act as an intermediate between IGF‑1R and PI3K/AKT signaling pathways

Chun-Lian Liang,Xiu-Li Li,Xiao-Juan Quan,Lin Zhang

Idiopathic pulmonary fibrosis (IPF) is a heterogeneous lung disease associated with high mortality. Disabled‑2 (DAB2), an adapter protein, regulates cell‑fibrinogen adhesion and fibrinogen uptake. DAB2 is differentially expressed in mouse fibrotic lungs induced by bleomycin according to a genome microarray analysis based on Gene Expression Omnibus database. However, the role of DAB2 in IPF has not been revealed. A bleomycin‑induced mouse model of pulmonary fibrosis was constructed in the present study. It found that the expression of DAB2 was upregulated in bleomycin‑induced fibrotic lung tissue with collagen fiber deposition and pulmonary interstitium thickening. Colocalization of DAB2 with α‑smooth muscle actin (SMA) was observed in lung tissue sections. In vitro, human lung fibroblast MRC‑5 cells were treated with TGF‑β1 and the expression of DAB2 was increased. Knockdown of DAB2 suppressed cell proliferation and the expression of α‑SMA, collagen I, collagen IV and fibronectin in TGF‑β1‑treated MRC‑5 cells. The phosphorylation levels of PI3K and AKT were suppressed in DAB2‑knockdown cells. IGF‑1/IGF‑1R has been reported to promote pulmonary fibrosis and activate the PI3K/Akt signaling. In the present study, the activation of IGF‑1/IGF‑1R signaling pathways in bleomycin‑induced fibrotic lung tissues were positively associated with DAB2 expression. The phosphorylation level of IGF‑1R was increased in MRC‑5 cells with TGF‑β1 treatment, and DAB2 expression was decreased by silencing of IGF‑1R. This suggested that DAB2 might be a downstream target of the IGF‑1R pathway and thus induced PI3K/AKT signaling activation and fibrogenesis. The current study demonstrated the importance of DAB2 in pulmonary fibrosis and suggested the potential of IGF‑1R/DAB2/PI3K in the pathogenesis of IPF.

Corylin accelerated wound healing through SIRT1 and PI3K/AKT signaling: a candidate remedy for chronic non-healing wounds

Xiu Yanghui,Su Yu,Gao Lihua,Yuan Hui,Xu Sennan,Liu Ying,Qiu Yan,Liu Zhen,Li Yuhang

Introduction: Chronic non-healing wound is a considerable clinical challenge and research into the discovery of novel pro-healing agents is underway as existing therapeutic approaches cannot sufficiently meet current needs.Method: We studied the effects of corylin in cell line fibroblasts and macrophages by Western blots, PCR, Flow cytometry assay, Immunofluorescence.Results: We showed that corylin, a main flavonoid extracted from Psoralea corylifolia L, reduced inflammatory responses, promoted collagen deposition, and accelerated the healing of full-thickness skin wounds in mice. Exploration of the underlying mechanisms showed that corylin activated the PI3K/AKT signaling, leading to fibroblasts’ migration, proliferation, and scratch healing. Corylin also activated sirtuin 1 (SIRT1) signaling, enhanced the deacetylation and cytoplasmic translocation of NF-κB p65, and therefore reduced lipopolysaccharide (LPS)-induced inflammatory responses in macrophages. Furthermore, inhibition of PI3K/AKT and sirtuin 1 pathway with LY294002 and EX527 prevent the therapeutic potency of corylin against chronic wounds.Conclusion: In summary, our results suggested that corylin may be a candidate for the development of novel pro-healing agents.

C-Phycocyanin Ameliorates the Senescence of Mesenchymal Stem Cells through ZDHHC5-Mediated Autophagy via PI3K/AKT/mTOR Pathway

Guoxiang Liu,Xiaoxia Li,Fanghao Yang,Jingyu Qi,Lipeng Shang,Huhu Zhang,Shuang Li,Fenghua Xu,Lingne Li,Huaxin Yu,Yang Li,Xiaolei Dong,Qinghang Song,Feng Zhu,Guang Chen,Can Cao,Liangqian Jiang,Junzhe Su,Lina Yang,Xiaohui Xu,Zhe Zhang,Robert Chunhua Zhao,Bing Li

The senescence of mesenchymal stem cells (MSCs) impairs their regenerative capacity to maintain tissue homeostasis. Numerous studies are focusing on the interventions and mechanisms to attenuate the senescence of MSCs. C-phycocyanin (C-PC) is reported to have multiple functions such as antitumor, antioxidation, anti-inflammation and anti-aging roles, but there is little research about the effects of C-PC on the senescence of MSCs. Here we investigated the roles and mechanism of C-PC on MSCs senescence. In vitro results showed that C-PC could reduce senescence, enhance proliferation, promote the adipogenic and osteogenic differentiation in senescent MSCs induced by oxidative stress. In vivo D-Galactose (D-Gal) induced rats aging models showed C-PC also increased the viability and differentiation of intrinsic senescent bone marrow derived MSCs (BMSCs). Furthermore, C-PC also decreased the levels of oxidative stress markers ROS or MDA, elevated the SOD activity, and increased the anti-inflammatory factors. Proteomic chip analysis showed that C-PC interacted with ZDHHC5, and their interaction was verified by pull down assay. Overexpression of ZDHHC5 aggravated the senescence of MSCs and greatly lessened the beneficial effects of C-PC on senescence. In addition, we found ZDHHC5 regulated autophagy by altering LC3, Beclin1 and PI3K/AKT/mTOR pathway. In summary, our data indicated that C-PC ameliorates the senescence of MSCs through zinc finger Asp-His-His-Cys (DHHC) domain-containing protein 5 (ZDHHC5) mediated autophagy via PI3K/AKT/mTOR pathway. The present study uncovered the key role of autophagy in MSCs senescence and PI3K/AKT/mTOR pathway may be a potential target for anti-senescence studies of MSCs.

Upregulation of miR-144-3p alleviates Doxorubicin-induced heart failure and cardiomyocytes apoptosis via SOCS2/PI3K/AKT axis

Donglin Zhang,Aiqin Pan,Jianke Gu,Renfeng Liao,Xueyu Chen,Zhaozhu Xu

MicroRNAs (miRs) are implicated in heart failure (HF). Thereby, we aim to uncover the role of miR-144-3p in HF. Doxorubicin (Dox)-induced HF model was constructed in rats and cardiomyocytes H9C2, and the cardiac function was determined using ultrasound cardiogram. Morphology of cardiac tissue was observed using hematoxylin–eosin (H&E) staining. The viability and apoptosis of Dox-treated and transfected cardiomyocytes were determined using Cell Counting Kit-8 (CCK-8) assay and flow cytometry. Relative expressions of the HF-associated miRs (including miR-144-3p), suppressor of cytokine signaling 2 (SOCS2), apoptosis- and phosphoinositide 3-kinase (PI3K)/AKT pathway-related factors (B-cell lymphoma 2, Bcl-2; Bcl-2 associated X protein, Bax; cleaved [C] capsase-3; phosphoinositide 3-kinase, PI3K; phosphorylated-PI3K, p-PI3K; p-AKT; AKT) were measured with quantitative real-time polymerase chain reaction or Western blot. Target gene of miR-144-3p was predicted by Starbase and TargetScan and confirmed with dual-luciferase reporter assay. Dox caused rat cardiac dysfunction, aggravated cardiac injury, decreased cardiomyocytes viability, and the expression of miR-144-3p, Bcl-2, and phosphorylation of both PI3K and AKT yet the upregulated those of Bax and C caspase-3, which was reversed by upregulating miR-144-3p, whereas downregulating miR-144-3p did oppositely. SOCS2 was the target gene of miR-144-3p, Dox promoted SOCS2 expression, which was reversed by upregulating miR-144-3p, while downregulating miR-144-3p did conversely. In addition, silencing SOCS2 reversed the effects of miR-144-3p downregulation in Dox-treated cardiomyocytes. Upregulating miR-144-3p alleviated Dox-induced cardiac dysfunction and cell apoptosis via targeting SOCS2, providing a novel evidence of miR-144-3p in HF.

Upregulation of SEMP1 Contributes to Improving the Biological Functions of Trophoblast via the PI3K/AKT Pathway in Preeclampsia

Chang Ruijing,Su Yuan,Kong Hongfang,Wang Fang,Xing Ying,Jiang Lei,Xin Hong

Disturbance of extravillous trophoblast infiltration is associated with preeclampsia (PE), a severe condition of pregnancy characterized by hypertension and proteinuria. Senescence-associated epithelial membrane protein 1 (SEMP1), an integral membrane protein, is a vital component of tight junction strands in epithelial or endothelial cells, with no clear function reported in PE. Gene Expression Omnibus (GEO) datasets showed that SEMP1 expression was downregulated in the placental tissues of PE patients, which was confirmed by assessing SEMP1 levels in placental samples collected in our hospital. Furthermore, less SEMP1 was detected in cytokeratin 7 positive trophoblast cells in the spiral arteries of rat placentas post L-arginine methyl ester hydrochloride (L-NAME) treatment. Trophoblast cells acquired robust ability of proliferation, migration, and invasion when SEMP1 was overexpressed. Such capability was weakened in SEMP1-silenced cells. Trophoblast cells overexpressing SEMP1 secreted more vascular endothelial growth factor A (VEGFA), which facilitated the tube formation of human umbilical vein endothelial cells. Blockade of PI3K/AKT signaling transduction with LY294002 dampened the effects of SEMP1 on trophoblast cells. Collectively, we firstly indicated that SEMP1 inhibition is a potential driver for PE, which may be associated with the deactivation of the PI3K/AKT pathway. Graphical Abstract SEMP1 was involved in PE progression by regulating cell growth, migration, invasion, and tube formation via PI3K/AKT signaling pathway in trophoblast cells and endothelial cells.
