Summary: This study found that polystyrene microplastics (PS-MPs) can cause lung injury in broiler chickens, leading to oxidative stress through inhibition of the PTEN/PI3K/AKT pathway and induction of autophagy and cell apoptosis. These results are of great significance to the toxicological study of PS-MPs and the protection of the ecosystem.

Summary: Ammonia induced autophagy in chicken BF by reducing ATPase activity and altering autophagy-related factors, leading to disturbance in energy metabolism. MiRNA-99a-3p was found to be the key player in this process.

Summary: The study revealed that imperatorin induces autophagy and cell cycle arrest through the PTEN-PI3K-AKT-mTOR/p21 signaling pathway by targeting and up-regulating PTEN in human osteosarcoma cells. Therefore, imperatorin is an ideal candidate for the clinical treatment of osteosarcoma.

Summary: The study reveals the significant role of YAP in vascular senescence, with inhibition or overexpression of YAP affecting the aging process in both cells and vascular tissues. Furthermore, YAP-induced senescence is associated with mTOR pathway activation and autophagic flux blockage, which can be relieved by YAP inhibition.

Summary: This study found that M. bovis infection inhibits cellular autophagy in bovine mammary epithelial cells through the PI3K-Akt-mTOR pathway, and that PTEN may act as a protective gene regulating autophagy to control infection.

Summary: Gliomas are common and lethal brain tumors, particularly glioblastomas, which pose a therapeutic challenge with poor prognosis. The transcriptional cofactors YAP and TAZ have emerged as crucial factors in malignancy, but their regulation in brain tumors remains unclear. This study investigated the link between EGFR and YAP/TAZ in glioblastomas and found an association between EGFR activation and YAP nuclear location. Pharmacological inhibition of EGFR resulted in increased YAP phosphorylation in PTEN wild-type cultures. These findings suggest the regulation of pS397-YAP by the EGFR-AKT axis in a PTEN-dependent manner, providing new insights into the pathogenesis of glioblastomas.

Summary: This study aims to investigate the potential regulatory relationship between PTEN and Akt/mTOR inhibition. The results reveal that inhibition of mTOR suppresses PTEN expression by upregulating miRNAs, providing a novel explanation for the limited efficacy of mTOR inhibitors in the treatment of mTOR activation-related tumors. This study also suggests that dual inhibition of mTOR and miRNA is a promising therapeutic strategy to overcome the resistance of mTOR-related cancer treatment.

Summary: Fluoride inhibits chondrocyte proliferation and promotes autophagy through the PI3K/AKT/mTOR signaling pathway in chondrogenesis. The study also showed that fluoride downregulates the mTOR signaling pathway-related genes and is associated with changes in autophagy-related gene expressions. MHY1485, a small-molecular mTOR activator, can reverse the fluoride-induced promotion of autophagy and recover the downregulation of proliferative chondrocyte markers induced by fluoride in chondrogenic cells.

Summary: This study aims to investigate the involvement of the PI3K/Akt/mTOR pathway during FeHV-1 infection. The results suggest that FeHV-1 may interact independently with different autophagic signaling pathways. Additionally, early phosphorylation of Akt after infection may be related to viral entry.

Summary: The study demonstrated that activation of Notch1 by doxycycline effectively suppressed cell proliferation and induced S phase arrest in osteosarcoma cells, while also triggering apoptosis and autophagy. Notch1 activation inhibited the PI3K/Akt/mTOR signaling pathway to induce apoptosis and autophagy.

Summary: Diabetic nephropathy is a major cause of chronic renal failure worldwide. In this study, increased Adenosine triphosphate (ATP) content was found in the urine of diabetic mice. The expression of purinergic P2X7 receptor (P2X7R) was significantly increased in the renal cortex of wild-type diabetic mice and partially co-localized with podocytes. P2X7R inhibition restored podocyte autophagy and may be a potential treatment for diabetic nephropathy.

Summary: This study aimed to investigate the potential anticancer activity and underlying mechanisms of rhein, a natural compound extracted from rhubarb, on oral cancer cells. The results showed that rhein significantly inhibited oral cancer cell growth by inducing apoptosis and S-phase cell cycle arrest. It also inhibited migration and invasion of oral cancer cells through the regulation of epithelial-mesenchymal transition-related proteins. Rhein exerted its anticancer activity by inducing oral cancer cell apoptosis and ROS accumulation via the AKT/mTOR signaling pathway in vitro and in vivo.
