Summary: The study found that decreased levels of retinol dehydrogenases (RDHs) in Pten-deficient mouse RPE lead to degeneration, which can be rescued by a ROL-free diet. It was also discovered that RDH gene expression is regulated by forkhead box O (FOXO) transcription factors, which are inactivated by hyperactive Akt in the Pten-deficient mouse RPE.

Summary: This study investigated the role of miR-363-3p in Cd-induced nephrotoxicity in occupational workers. The findings suggest that the increase of miR-363-3p is associated with down-regulation of PI3K and suppressed proliferation and enhanced apoptosis of renal tubule epithelial cells. MiR-363-3p may be considered for possible therapeutic strategies for Cd-associated kidney damage.

Summary: MicroRNA-25-3p has been shown to be upregulated in multiple myeloma tissues and cell lines, and this upregulation is associated with poor prognostic markers. The miR-25-3p regulates the PI3K/AKT signaling pathway by targeting the tumor suppressor PTEN, leading to promotion of cancer progression in multiple myeloma.

Summary: This study investigated the effects of Ang II on cardiac injury and found that it can lead to cardiac apoptosis by attenuating the IGF1R-PI3K-AKT pathway and activating miR-320-3p transcription. Furthermore, a reduction in IGF1R survival pathway activation was observed in the heart tissue of spontaneously hypertensive rats.

Summary: Activated autophagic flux in SGNs after cisplatin treatment can alleviate SGN apoptosis and related hearing loss, indicating a neuroprotective role of autophagy. The antioxidant enzyme PRDX1 plays a crucial role in modulating autophagy in SGNs, which in turn activates the PTEN-AKT signaling pathway to trigger autophagy. These findings suggest potential therapeutic targets for drug-induced SNHL through autophagy activation.

Summary: Resveratrol exerts neuroprotective effects on primary cortical neurons subjected to oxygen/glucose deprivation/reoxygenation (OGD/R) by modulating mitophagy, improving cell viability, suppressing apoptosis, alleviating loss of mitochondrial membrane potential and excessive oxidative stress. The protective effects are mediated, at least in part, by promoting mitophagy through the PTEN-induced kinase 1/Parkin pathway.

Summary: This study investigated the impact of miR-375-3p in EPCs-EVs on myocardial injury in sepsis, demonstrating that up-regulating miR-375-3p can ameliorate myocardial damage. The findings suggest that miR-375-3p alleviates myocardial injury by targeting BRD4 to activate the PI3K/AKT pathway.

Summary: The study revealed that miR-146b-3p inhibits the proliferation, migration, and phenotype switch of VSMCs induced by PDGF-BB through targeting the PIK3CG pathway. This suggests that miR-146b-3p/PIK3CG could be a potential target for the treatment of atherosclerosis.

Summary: The study identified that excessive phosphorylation of Mfn2 leads to proteasomal degradation in PAH and NSCLC, and inhibiting this phosphorylation may hold therapeutic potential for these diseases. By modifying Mfn2 constructs, it was shown that increasing Mfn2 expression can suppress cell proliferation and induce apoptosis in these conditions.

Summary: The study demonstrates that downregulation of GAS5 or upregulation of miR-455-5p improves neurobehavior, reduces apoptosis and oxidative damage in brain tissues of ischemic stroke (IS) rats. Additionally, downregulation of miR-455-5p counteracts the inhibitory effect of GAS5 on IS.

Summary: This study investigated the role of long non-coding RNA RMST in ischemic stroke through the miR-221-3p/PIK3R1/TGF-beta axis in MCAO mice. The results showed that elevated RMST and PIK3R1, downregulated miR-221-3p, and activated TGF-beta pathway were associated with MCAO, and restoring miR-221-3p or depleting RMST improved neurological functions and pathological damage. Additionally, depleting PIK3R1 or restoring miR-221-3p could counteract the negative effects of RMST overexpression in MCAO mice.

Summary: Angiosarcoma is a rare and highly aggressive malignant tumor derived from endothelial cells. This study found significantly lower PTEN expression but higher PIK3CA, pMAPK, and TP53 expression in angiosarcoma compared to benign hemangioma. The presence of apoptosis and correlation with tumor differentiation in angiosarcoma suggest potential therapeutic targets in the PI3K, MAPK, and TP53 pathways.
