DNA ligase LigE increases bacterial transformation with damaged extracellular DNA
FEBS Letters, EarlyView.The DNA ligase LigE from the naturally competent Gram‐negative bacterium Neisseria gonorrhoaea increases transformation with cut extracellular DNA. This process is ATP‐dependent and relies on the catalytic activity of LigE; it also requires that LigE contains an intact periplasmic localisation sequence, indicating that ligE functions in the periplasm ...

Abrasion Resistance of Thermoplastic Polyurethane in Abrasion Resistance Test Using Abrasives.
KOBUNSHI RONBUNSHU, 1992 ポリカプロラクトン, 4, 4'-ジフェニルメタンジイソシアナート, 1, 4-ブタンジオールからなる熱可塑性ポリウレタンのうち組成比の異なる2種類の試料について, 研磨材を用いた摩耗試験を行った. その結果, 硬さが小さく, 動的貯蔵弾性率 (E') の小さい試料が耐摩耗性が良好であった. また, 温度を上げた状態での摩耗試験の結果, 及び加圧下でのポリウレタンと鋼球の接触状態の観察から, E'の低い試料では, 研磨材との接触面積が大きくなり, 研磨材と一体となった層を形成するため, 耐摩耗性が向上するものと考えられた.

Molecular Oncology, EarlyView.LUNAR is a liver‐specific long noncoding RNA (lncRNA) that is highly expressed in normal liver but becomes epigenetically silenced in hepatocellular carcinoma through promoter hypermethylation. Loss of LUNAR is associated with NOTCH activation, epithelial–mesenchymal transition, and metastasis, whereas restoring LUNAR restrains metastatic progression ...

Molecular Oncology, EarlyView.This study identifies ARHGAP5, in addition to the frequently mutated ARHGAP35, as significantly mutated in endometrial cancer. Mutations in both genes co‐occur and are associated with their correlated downregulation. Functional CRISPR studies show that both paralogs regulate similar pathways, including actin cytoskeleton organization.
