The established recognition of N6-methyladenosine (m6A) modification as an indispensable regulatory agent in human cancer is widely accepted. However, the understanding of m6A's role and the mechanisms underlying its contribution to gefitinib resistance is notably limited. Herein, using RT-qPCR, Western blot, Cell proliferation and apoptosis, as well as RNA m6A modification assays, we substantiated that heightened FTO (Fat Mass and Obesity-associated protein) expression substantially underpins the emergence of gefitinib resistance in NSCLC cells.

Studies have demonstrated that phycocyanin has potential regulatory effects on glycometabolism, while its function and mechanism, especially in type 2 diabetes mellitus (T2DM), is still unclear. The aim of this study was to investigate the antidiabetic roles and underlying mechanism of phycocyanin in a high glucose high fat diet induced model of T2MD in C57BL/6N mice and a high-insulin-induced insulin-resistant model of SMMC-7721 cells.

In this study, we used the naturally aging and D-galactose-induced aging mice as animal models to study the anti-aging effects of AAPS via the alleviation of oxidative stress and regulation of gut microbiota. Results showed that AAPS could significantly prolong lifespan and alleviate oxidative stress induced by HO of .

Several malignancies involve dysregulated long noncoding ribonucleic acids (lncRNAs) in non-small cell lung cancer cell growth and their aggressive phenotypes. LncRNA B4GALT1-AS1 is important in the advancement of various malignancies, although its contribution to non-small cell lung cancer (NSCLC) remains unexplored.

Drug resistance is a critical factor responsible for the recurrence of non-small cell lung cancer (NSCLC). Previous studies suggest that curcumin acts as a chemosensitizer and radiosensitizer in human malignancies, but the underlying mechanism remains elusive. In the present study, we explored how curcumin regulates the expression of miR-142-5p and sensitizes NSCLC cells to crizotinib.

However, the underlying mechanism involved in phycocyanin-mediated anti-growth function on non-small cell lung cancer (NSCLC) cells is still ambiguous. Here, we investigated the mechanism of action of phycocyanin on H1299, A549, and LTEP-a2 cells.

All the NSCLC patients who participated in this research were recruited from the Second Hospital of Hebei Medical University. PC9 cells and PC9GR cells were cultured for experiments.

Relative expression levels of MIAT, Pellino E3 Ubiquitin Protein Ligase Family Member 3 (PELI3), and microRNA (miR)-128-3p were analyzed by real-time polymerase chain reaction. PELI3 protein level was determined by immunoblotting.
