Summary: The study found that TMPO-AS1 is highly expressed in gastric cancer tissues and cells, promoting proliferation, migration, and angiogenesis of gastric cancer cells, and upregulating BRCC3 expression by acting as a competing endogenous RNA for miR-126-5p. The TMPO-AS1/miR-126-5p/BRCC3 axis contributes to gastric cancer progression by regulating the PI3K/Akt/mTOR pathway.

Summary: miR-18b-5p is downregulated while PTEN is upregulated in follicular fluid exosomes of PCOS patients. Decreasing PTEN promotes KGN cell proliferation and limits apoptosis. Exosomes stimulate KGN cell proliferation and suppress apoptosis, decrease FSH, LH, and testosterone levels, and increase E2 levels. Upregulating miR-18b-5p enhances the inhibitory effects of exosomes on PCOS progression. miR-18b-5p improves PCOS by targeting PTEN and activating the PI3K/Akt/mTOR pathway. Circulating miR-18b-5p levels are associated with the progression of PCOS complications.

Summary: Increasing evidence has shown that ALDH1A3 is closely associated with tumorigenesis, therapy resistance, and prognosis in various cancers. This study demonstrates that ALDH1A3 is highly expressed in GBM cells and plays a critical role in their proliferation and radioresistance. The study also identifies miR-4524b-5p as an upstream regulator of ALDH1A3 and shows that overexpression of miR-4524b-5p reduces proliferation and radioresistance in GBM cells. Targeting the miR-4524b-5p and ALDH1A3 axis could be a promising therapeutic strategy for treating GBM.

Summary: This study reveals that subacute CdCl2 exposure induces apoptosis and tissue damage in piglet adrenal gland. The exposure leads to a decrease in antioxidant enzymes, increase in heat shock protein, and upregulation of the miR9-5p-gene of PTEN, which activates the PI3K/AKT pathway. Activation of this pathway results in a significant increase in apoptosis-related factors and tissue damage.

Summary: Type 2 diabetes is a global health issue that requires measures for treatment and prevention of related complications. This study found that synthetic PPAR alpha/Upsilon partial agonists have significant therapeutic effects on high-fat diet/streptozotocin-induced diabetes in rats, improving vascular function by reducing vascular inflammation and increasing the expression of microRNA.

Summary: This study investigated the potential role and underlying mechanisms of linc00174 in the pathogenesis of diabetic retinopathy (DR). The results revealed that linc00174 was involved in the regulation of pyroptosis, possibly through the miR-26a-5p/PTEN/Akt signaling cascade. This research is of great significance for the development of potential therapeutic agents for DR treatment.

Summary: This study investigates the mechanism of microRNA-188-5p (miR-188-5p) mediated drug resistance to doxorubicin (ADM) in acute myeloid leukemia (AML). Differentially expressed miRNAs were screened, and it was found that miR-188-5p was highly expressed in AML cells. Inhibition of miR-188-5p increased the sensitivity of AML/ADM cells to ADM. The study also revealed that TET1 promotes the hydroxymethylation of miR-188-5p promoter, leading to increased miR-188-5p expression. Furthermore, miR-188-5p inhibits PTEN expression, activating the PI3K/AKT signaling pathway and resulting in ADM resistance in AML.

Summary: Prostate cancer (PCa) is a common cancer in men, and the androgen receptor (AR) plays a crucial role in its development and progression. Although AR signaling inhibitors (ARSIs) have shown effectiveness in castration-sensitive PCa (CSPC) and improved survival, men with castration-resistant PCa (CRPC) still have a poor prognosis. Resistance to ARSIs in metastatic CRPC is commonly observed due to AR mutations and hyperactivation of the PI3K/AKT/mTOR pathway. The interaction between AR and the PI3K/AKT/mTOR signaling pathway in PCa has been well-documented.
