Rutin inhibits prostate cancer progression by suppressing EMT, inducing mitochondrial biogenesis, and acting via ER stress-linked AMPK/SIRT1 signaling. These findings suggest that Rutin may serve as a potential therapeutic candidate for advanced prostate cancer.

In summary, this study identified lncRNAs associated with NDMM and characterized LINC01432 as a critical regulator of MM cell survival, acting in complex with CELF2 to repress pro-apoptotic and immune response pathways. These findings highlight LINC01432 as a potential therapeutic target for overcoming resistance in MM.

For the hepatic BAs profile, YGYZ increased the content of primary BAs-Nor cholic acid (NorCA), Taurocholic acid, Taurochenodeoxycholic Acid, and Tauro β-Muricholic Acid, and secondary BAs-ursodeoxycholic acid (UDCA), with similar trends in FMT, while YGYZ decreased NorCA, α-Muricholic acid, Tauro α-Muricholic acid, and UDCA in the fecal BA profile. YGYZ and its FMT dampened the protein expression of IL-6, STAT3, and pSTAT3, but only YGYZ downregulated kruppel-like factor 15 (KLF15). YGYZ may prevent LM by remodeling the GM and synergistically inhibiting KLF15 to regulate the enterohepatic BA cycle, and suppressing the proliferation and activation of myeloid-derived suppressor cells through the IL-6/STAT3 pathway, thereby improving IME of liver PMN.

In this study, we observed that the lipid peroxide scavenger Liproxstatin-1 unexpectedly promoted TNF-α-induced apoptosis in HT-29 cells and murine colonic organoids, in contrast to the protective effects previously reported for typical peroxide scavengers in UC...Furthermore, 4-HDHA suppressed NF-κB signaling and apoptosis via PPARγ activation. Collectively, these findings demonstrate that 4-HDHA, identified through targeted lipidomics, attenuates DSS-induced colitis by reducing apoptosis and inflammation through PPARγ activation, highlighting its potential as a promising therapeutic agent for UC.

LncRNA HOXA11-AS is aberrantly overexpressed in ESCC and functions as an oncogene, driving tumor progression by enhancing proliferation, migration, invasion and suppressing apoptosis. Its association with poor prognosis identifies HOXA11-AS as a promising prognostic biomarker and potential therapeutic target for ESCC.

Treatment of the Huh-7 and HepG2 cells exposed to fructose with ursodeoxycholic acid (UDCA) or its taurine-conjugated form, TUDCA, which are known to elicit protective hepatocellular effects by inducing antioxidant defenses, strongly inhibited succinate build up by preserving mitochondrial function and preventing H2O2 hyper-production. Collectively, our findings show succinate accumulates rapidly in the extracellular milieu in our mouse model for MASLD and cell culture models for hepatic lipotoxicity. These findings suggest the applicability of succinate as a biomarker of early MASLD particularly among males and especially in pediatric populations.

Furthermore, the phosphorylation of phosphatidylinositol 3-kinase (PI3K), AKT and mammalian target of rapamycin (mTOR) was inhibited by BBR-CA, contributing to decreased active SREBP-1 in the nucleus, and was reversed and enhanced by the PI3K agonist recilisib and inhibitor LY294002, respectively. Taken together, our results suggest that BBR-CA could function by modulating the PI3K/AKT/mTOR signaling pathway, resulting in decreased nuclear expression of SREBP-1, as well as reduced expression of stearoyl-CoA desaturase 1 and acetyl-CoA carboxylase, thus alleviating hyperlipidemia. Further experimental validation is required to confirm these results.

Network pharmacology results indicated that SA might alleviate MASH through the phosphoinositide 3-kinase (PI3K)/protein kinase B (AKT)/(Mechanistic target of rapamycin) mTOR signaling pathway. Notably, the PI3K activator Recilisib weakened the inhibitory effect of SA on PA-induced p-AKT and COL1a1 in LX-2 cells, further confirming the dependence of SA on PI3K activity. In conclusion, we identified SA as a potential natural PI3K inhibitor and promising compound for the treatment of MASH.
