    “…We evaluated thymomas and thymic carcinomas by next-generation sequencing (NGS) of somatic or germline single nucleotide variants (SNVs) in genes commonly mutated in solid tumours. In total, 19 thymomas and 34 thymic carcinomas were analysed for nonsynonymous SNVs in 15 genes by targeted NGS (reference genome: hg19/GRCh37). …”

    “…Furthermore, our findings demonstrated that mutations and sCNA of the KCNQ1OT1/miR-378a-3p/RBMS1 axis were associated with increased immune infiltration, while the abnormal upregulation of the axis was primarily a result of hypomethylation. …”

    “…The common cellular mechanisms shared by the mutant γ-amino butyric acid transporter 1 and cystic fibrosis transmembrane conductance regulator led us to hypothesize that 4-phenylbutyrate could be a potential treatment option for solute carrier Family 6 Member 1 mutations. We examined the impact of 4-phenylbutyrate across a library of variants in cell and knockin mouse models. …”

    “…Rare deep-intron variants (n = 6), putatively acting as pseudo-exon activating mutations, have been characterized as pathogenic. Some variants have been characterized as benign/likely benign/of uncertain significance (n = 74). …”

    “…The sequencing of 13 specimens, which included 1 mother-newborn dyad, indicated clustering to the same phylogenetic lineage with identical mutations. In assessing for factors contributing to this outbreak, it was found that spaces between beds were less than 1 m and mothers had their meals around the same table at the same time. …”

    “…Since first reported in 2019, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is rapidly acquiring mutations, particularly in the spike protein, that can modulate pathogenicity, transmission and antibody evasion leading to successive waves of COVID19 infections despite an unprecedented mass vaccination necessitating continuous adaptation of therapeutics. …”

    “…Its genome, an RNA of 29,903 nucleotides, shows strong homogeneity with bat coronaviruses from southern China, but the conditions for its passage in humans have yet to be elucidated. Mutations can give rise to variants of concern (VOC) that are more transmissible and able to evade the host's immune response. …”

    “…The results showed that tumor cells presenting mutations in mitochondrial DNA (mtDNA) (L929dt and L929(dt) cybrid cells) and reliant on glycolysis for survival were more sensitive to cell death induced by PT-112 compared to the parental and cybrid cells with an intact oxidative phosphorylation (OXPHOS) pathway (L929 and dt(L929) cybrid cells). …”

    “…ST17 isolates from China fell into Clade IV with part of isolates from the United Kingdom, the United States, South Korea, and Thailand, suggesting their close genetic relationship. Mutations in quinolone resistance-determining regions (QRDR) of GyrA and ParC, and plasmid-mediated quinolone resistance (PMQR) genes aac(6′)-Ib-cr, oqxAB, and qnrS as well as extended spectrum β-lactamases (ESBL) genes bla(CTX-M), bla(OXA), and bla(TEM) in isolates from Clade IV were much higher than those from other three clades. …”

    “…Further studies showed that MM102 effectively inhibited cisplatin-triggered DNA damage response (DDR), as indicated by dephosphorylation of ataxia telangiectasia mutated (ATM) and ATM and Rad-3 related (ATR) proteins, dephosphorylation of checkpoint kinase 1 and 2 (Chk1 and Chk2); depression of γ-H2AX; and restrained cell cycle arrest, as evidenced by decreased expression of p21 and phospho-histone H3 at serine 10 in vitro and in vivo. …”

    “…This analysis pooled prospective data to compare the survival benefits of the two regimens for advanced NSCLC without targetable genetic mutations. METHODS: Data were pooled from three randomised phase III clinical trials: NCT03607539, NCT03134872 and NCT02954172. 466 patients received PD-1 inhibitor (200 mg) plus pemetrexed (500 mg/m²) and platinum (cisplatin 75 mg/m(2) or carboplatin area under the curve (AUC) 5 mg/mL/min), while 432 patients received bevacizumab (15 mg/kg) plus paclitaxel (175 mg/m(2)) and carboplatin (AUC 6 mg/mL/min). …”

    “…The expression of Regulator of chromatin condensation 1/small nucleolar RNA host gene 3/small nucleolar RNA host gene12 in BRCA, LGG and LIHC was associated with TP53 mutations. In addition, Regulator of chromatin condensation 1/small nucleolar RNA host gene 3/small nucleolar RNA host gene12 expression was closely associated with the prognosis of patients with multiple tumors. …”
