This study aims to elucidate the role of mitophagy-related genes (MRGs) in cutaneous melanoma (CM) through single-cell RNA sequencing (scRNA-seq) and machine learning approaches, ultimately developing a predictive model for patient prognosis. The scRNA-seq data, bulk transcriptomic data, and clinical data of CM were obtained from publicly available databases. The single-sample gene set enrichment analysis (ssGSEA) and weighted gene co-expression network analysis (WGCNA) were used to identify gene modules associated with mitophagy phenotypes. A machine learning framework employing ten different algorithms was used to develop the prognostic model. Based on scRNA-seq data, we identified 16 distinct cell subpopulations in melanoma, and melanoma cells exhibited significantly higher mitophagy scores. The turquoise module identified via WGCNA showed the strongest correlation with mitophagy scores. A prognostic model incorporating seven genes was developed through machine learning algorithms, achieving an average C-index of 0.754 across training and validation cohorts. Functionally, low-risk patients were enriched in interferon-gamma response and inflammatory processes, whereas high-risk patients showed enrichment in glycolysis regulation and signaling pathways such as KRAS and Wnt/β-catenin. Notably, low-risk patients demonstrated enhanced immune infiltration and greater sensitivity to immunotherapy. RT-qPCR validated the expression level of 7 model genes in human melanoma cell lines and normal melanocyte cell lines.

Based on our recent finding to study the potential effect of mTOR on ATG13 inactivation in chronic muscle fatigue, we report that biweekly oral administration with MHY1485, a potent inducer of mTOR, develops chronic illness in mice resulting in severe muscle weakness. As a mechanism, we observed that MHY1485 feeding impaired ATG13-dependent autophagy, caused the infiltration of inflammatory M1 macrophages (Mφ), upregulated IL6 and RANTES by STAT3 activation, and augmented demyelination in muscle-serving nerve fibers. Interestingly, these mice displayed worsened muscle fatigue during 2-day post-treadmill exercise, suggesting the critical role of chronic mTOR activation in potential PEM pathogenesis. Interestingly, ATG13-repressor mice exhibited enhanced infiltration of M1Mφ cells, STAT3 activation, demyelination of nerve fibers, and PEM-like symptoms, suggesting the potential role of ATG13 impairment in post-exertional fatigue.

Data were obtained from the Global Burden of Disease (GBD) 2021 study. Trends in ASIR, ASPR, and ASMR were analyzed using Joinpoint regression to calculate annual percentage change (APC) and average APC (AAPC). Bayesian age-period-cohort (BAPC) modeling was applied to project future ASIR trends. In 2021, asthma had the highest ASIR (364.17/100,000), followed by psoriasis (59.70/100,000) and RA (13.70/100,000), while MS (0.16/100,000) and IBD (1.40/100,000) were the least common. Asthma exhibited significant declines in ASIR (-1.23% AAPC), ASPR (-1.49%), and ASMR (-4.4%). Conversely, T1DM showed rising ASIR (+ 1.16%) and ASPR (+ 1.15%) alongside declining ASMR (-2.62%). Psoriasis (+ 0.74%) and IBD (+ 2.09%) also showed rising ASIR. Gender differences were notable, with greater T1DM ASIR increases in males and more significant asthma improvements in females. By 2046, the ASIR of T1DM, psoriasis, and RA is projected to reach 5.8, 80.9, and 15.54 per 100,000, respectively, while asthma is expected to decline to 330.98 per 100,000.
