- Metabolic reprogramming is a hallmark of lung adenocarcinoma (LUAD) progression and therapy resistance, yet its clinical integration for prognosis and treatment remains limited. This study aimed to develop a metabolism-related prognostic score (MRPs) and investigate its biological, immunological, and therapeutic implications in LUAD. - Source: PubMed

Jia JiabaoFeng ShiyunWang RuiZhao XiaoshuangCui Youbin - The tumor microenvironment in colorectal cancer (CRC) is marked by a diverse and abundant population of cancer-associated fibroblasts (CAFs), which play a crucial role in radioresistance. Nonetheless, the mechanisms through which CAFs contribute to radioresistance remain unclear. In this study, we demonstrate that CAF, a specific subset of CAFs derived from radioresistant CRC patients, produces higher levels of transforming growth factor-β1 (TGF-β1) compared to CAFs isolated from radiosensitive CRC patients. Through long noncoding RNA (lncRNA) profiling of tumor cells treated with CAF-conditioned medium (CAF-CM), we identify WARS2-IT1 (WARS2 intronic transcript 1), whose expression is directly stimulated by TGF-β1 signaling. This lncRNA serves as a key player in promoting radioresistance and is essential for the TGFβ1-induced radioresistance pathway. Mechanistically, WARS2-IT1 interferes with the interaction between prolyl hydroxylase domain 2 (PHD2) and hypoxia-inducible factor-1α (HIF-1α), preventing the hydroxylation and subsequent degradation of HIF-1α. This process leads to the activation of glycolytic pathways, thereby enhancing radioresistance. Our findings underscore the potential of targeting CAF-driven WARS2-IT1 as a promising strategy to counteract tumor radioresistance in CRC. - Source: PubMed

Li YuanqiDai WeiZheng XiaoWang QiZhang JinpingKong XiangyinJiang JingtingZhou You - Fibroblast growth factor 21 (FGF21), a pleiotropic hormone, is a significant modulator of energy homeostasis. We evaluated serum FGF21 levels in patients with a deficiency of mitochondrial aminoacyl-tRNA synthetase (mt-aARSs). Six patients with mitochondrial aminoacyl tRNA synthetase deficiency and twelve healthy volunteers were included in this study. Whole-exome sequencing was used for molecular diagnosis. Serum FGF21 levels in the case group and healthy volunteers were analyzed using the enzyme-linked immunosorbent assay. Exome sequencing test revealed nine different pathogenic variants in the , , , , and genes. A statistically significant difference was found between the serum FGF21 levels of the case and control groups: case group (n = 6), 882.49 ± 923.60 pg/mL; control group (n = 12), 20.89 ± 2.63 pg/mL ( < 0.001). The area under the ROC curve for FGF21 in the differential diagnosis of mitochondrial aminoacyl-tRNA synthetase deficiency was 1.000 (0.813-1.000). Sensitivity and specificity were 100%, and positive and negative predictive values were also 100% for an FGF21 cut-off value > 27.4 pg/mL. Assessment of FGF 21 levels as an indicator of mitochondrial damage in mt-aARSs deficiency may provide insight into the level of damage. Investigation of the biochemical mechanisms underlying the different levels of damage caused by different aminoacyl tRNA synthetases will be important in terms of elucidating clinical heterogeneity. - Source: PubMed

Tekin Neijmann SebnemGunes DilekKaraca MeryemKaraman VolkanBalci Mehmet CihanGokcay Gulden FatmaGedikbasi Asuman - Mitochondrial WARS2 -related disorders are known to exhibit a broad phenotypic spectrum, ranging from infantile-onset epilepsy syndromes to hyperkinetic movement disorders. We report a case of an 11-year-old male who presented with tremors, dystonic falls, social anxiety, and impulse control disorder (ICD), with onset at 6 years of age. Genetic analysis revealed a likely compound heterozygous mutation in the WARS2 gene, involving exon 4 (p.Thr154ProfsTer66) and exon 1 (p.Trp13Gly). He demonstrated a remarkable clinical response to levodopa. This case is notable for its rarity and to our knowledge, represents the first reported instance of a WARS2 -related disorder from India. - Source: PubMed
