The antidepressant drug sertraline is a novel inhibitor of yeast Pah1 and human lipin 1 phosphatidic acid phosphatases by Geordan J. Stukey, Matthew R. Breuer, Natalie Burchat, Ruta Jog, Kollin Schultz, Gil-Soo Han, Matthew S. Sachs, Harini Sampath, Ronen Marmorstein, George M. Carman

“…That Pah1 is a physiological target of sertraline in S. cerevisiae is supported by the observations that the overexpression of PAH1 rescued the sertraline-mediated inhibition of pah1Δ mutant cell growth, the lethal effect of overexpressing Pah1-CC was rescued by sertraline supplementation, and that a sublethal dose of the drug resulted in a 2-fold decrease in TAG content.…”

Anti-proteolytic regulation of KRAS by USP9X/NDRG3 in KRAS-driven cancer development by Han Koo, Kyung Chan Park, Hyun Ahm Sohn, Minho Kang, Dong Joon Kim, Zee-Yong Park, Sehoon Park, Sang Hyun Min, Seong-Hwan Park, Yeon-Mi You, Yohan Han, Bo-Kyung Kim, Chul-Ho Lee, Yeon-Soo Kim, Sang J. Chung, Young Il Yeom, Dong Chul Lee

“…Here, we report that KRAS expression is post-translationally up-regulated through deubiquitination when the scaffolding function of NDRG3 (N-Myc downstream-regulated gene 3) promotes specific interaction between KRAS and a deubiquitinating enzyme, USP9X. In KRAS-mutant cancer cells KRAS protein expression, downstream signaling, and cell growth are highly dependent on NDRG3. …”

Host genetics and gut microbiota influence lipid metabolism and inflammation: potential implications for ALS pathophysiology in SOD1G93A mice by Elena Niccolai, Leandro Di Gloria, Maria Chiara Trolese, Paola Fabbrizio, Simone Baldi, Giulia Nannini, Cassandra Margotta, Claudia Nastasi, Matteo Ramazzotti, Gianluca Bartolucci, Caterina Bendotti, Giovanni Nardo, Amedeo Amedei

“…Using 16 S rRNA sequencing and fecal metabolite analysis, we characterized the GM composition and metabolite profiles in non-transgenic (Ntg) and SOD1G93A mutant mice of both strains. Our results revealed strain-specific differences in GM composition and functions, particularly in the abundance of taxa belonging to Erysipelotrichaceae and the levels of short and medium-chain fatty acids in fecal samples. …”

Tp53 determines the spatial dynamics of M1/M2 tumor-associated macrophages and M1-driven tumoricidal effects by Yi-Jing Hsiao, Min-Shu Hsieh, Gee-Chen Chang, Yin-Chen Hsu, Chia-Yu Wang, Yan-Ming Chen, Yi-Ling Chen, Pan-Chyr Yang, Sung-Liang Yu

“…Additionally, dominance of islet M1 TAMs and M1-signature were significantly associated with improved survival in patients with wtp53 lung adenocarcinoma, unlike in those with mutant TP53. Conditioned medium from M1 macrophages (M1 CM) induced apoptosis in wtp53 cells through increased p53 accumulation. …”

H-NS controls the susceptibility of Escherichia coli to aminoglycosides by interfering its uptake and efflux by Qiuru Chen, Yulei Liang, Yanbin Dong, Junling Cui, Kun He, Xiaoyuan Ma, Jinfeng Zhao, Jinfeng Zhao, Yajun Zhai, Yajun Zhai, Li Yuan, Li Yuan, Li Yuan, Li Yuan

“…H-NS is a histone-like nucleoid-structuring protein that regulates gene expressions, particularly acquired foreign genes, however, little is known about whether H-NS can modulate bacterial susceptibility by regulating its intrinsic genes. The hns-deleted mutant EΔhns, the hns-complemented strain EΔhns/phns and the hns-overexpressed strain E/phns were derivatives of Escherichia coli ATCC 25922, the susceptibility of which were assessed by the broth microdilution method and time-kill curves assays. …”
