    “…Front line therapy was ≥4 cycles of platinum doublet therapy or ≥3 months of inhibitors of epidermal growth factor receptor (EGFR) or anaplastic lymphoma kinase (ALK) for patients with EGFR mutations or ALK rearrangements. Patients were randomized to either LCT ([chemo]radiation or resection of all lesions) +/− maintenance therapy versus maintenance therapy/observation only. …”

    “…C1q appeared to interact with DC-SIGN or DC-SIGNR in a manner similar to IgG. Mutational analysis using single amino acid substitutions within the globular head modules showed that Tyr(B175) and Lys(B136) were critical for the C1q–DC-SIGN/DC-SIGNR interaction. …”

    “…There was no difference in the frequency of mutations between PvMCA1-cd and Pvmdr1 (P > 0.2). Histidine and cysteine residues in PvMCA1-cd are highly polymorphic and linkage disequilibrium with SNPs of Pvmdr1 gene may be expected from these three areas with different patterns of P. vivax transmission.…”

    “…Additionally, we analyzed the amino acid sequences of potential HisN, ImpA, SuhB, CysQ and Cg0911 orthologs from bacteria and identified six conserved sequence motifs for each group of orthologs. Mutational studies confirmed the importance of a highly conserved aspartate residue accompanied by several aromatic amino acid residues present in motif 5 for HolPase activity. …”

    “…TSC is caused by inactivating mutations in the TSC1 or TSC2 genes. Heterozygocity induces hyperactivation of mTOR which can be inhibited by mTOR inhibitors, such as rapamycin, which have proven efficacy in the treatment of TSC-associated symptoms. …”

    “…The linkage of pleuromutilin susceptibility and sequence type of an isolate might reflect a clonal expansion of the underlying resistance mechanism, namely mutations in the ribosomal RNA genes. A linkage between single virulence-associated genes (VAGs) or even VAG patterns and the phylogenetic background of the isolates could not be established, since almost all VAGs were regularly present in the isolates.…”

    “…BACKGROUND: Acute myeloid leukemia (AML) is a heterogeneous group of hematopoietic malignancies due to sophisticated genetic mutations and epigenetic dysregulation. MicroRNAs (miRNAs), a class of small non-coding RNAs, are important regulators of gene expression in all biological processes, including leukemogenesis. …”

    “…P150(Glued) also initiates dynein-mediated axonal retrograde transport. Multiple missense mutations at the CAP-Gly domain of p150(Glued) are associated with motor neuron diseases and other neurodegenerative disorders, further supporting the importance of microtubule domains (MTBDs) in p150(Glued) functions. …”
