Background and References Cytosolic and membrane-bound forms of glutathione S-transferase are encoded by two distinct supergene families. At present, eight distinct classes of the soluble cytoplasmic mammalian glutathione S-transferases have been identified: alpha, kappa, mu, omega, pi, sigma, theta and zeta. GSTM3 is a glutathione S-transferase that belongs to the mu class. The mu class of enzymes functions in the detoxification of electrophilic compounds, including carcinogens, therapeutic drugs, environmental toxins and products of oxidative stress, by conjugation with glutathione. The genes encoding the mu class of enzymes are organized in a gene cluster on chromosome 1p13.3 and are known to be highly polymorphic. These genetic variations can change an individual's susceptibility to carcinogens and toxins as well as affect the toxicity and efficacy of certain drugs. Mutations of this class mu gene have been linked with a slight increase in a number of cancers, likely due to exposure with environmental toxins.Cytosolic and membrane- bound forms of glutathione S-transferase are encoded by two distinct supergene families.

  • Low GSTM3 Expression Is Associated with Poor Disease‐Free Survival In
    Yang et al. Diagnostic Pathology (2021) 16:10 https://doi.org/10.1186/s13000-021-01069-4 RESEARCH Open Access Low GSTM3 expression is associated with poor disease‐free survival in resected esophageal squamous cell carcinoma Fu Yang1,2,3,4, Jing Wen2,3,4, Kongjia Luo2,3,4 and Jianhua Fu2,3,4* Abstract Background: Glutathione S-transferase mu 3 (GSTM3) plays a crucial role in tumor progression in various cancers. However, the relationship between GSTM3 expression and the clinical prognosis of esophageal squamous cell carcinoma (ESCC) has not been studied to date. We aimed to characterize the role of GSTM3 in predicting postoperative prognosis of ESCC patients. Methods: In the retrospective study, GSTM3 mRNA levels in 184 ESCC tissues and matched 43 adjacent nontumorous tissues were measured by quantitative real-time PCR. GSTM3 protein levels in 247 ESCC tissues were measured by immunohistochemistry. Results: Downregulation of GSTM3 occurred in 62.8 % of primary ESCC tissues compared with their nontumor counterparts. Patients with low GSTM3 expression tended to exhibit an increased rate of poor differentiation in both the mRNA cohort (p = 0.024) and protein cohort (p = 0.004). In the mRNA cohort, low GSTM3 expression was associated with unfavorable 3-year disease-free survival (DFS) (39.2 % vs. 57.4 %) and 5-year DFS (26.8 % vs. 45.1 %) (p = 0.023). The result was confirmed in the protein cohort. Patients with low GSTM3 expression had unfavorable 3-year disease-free survival (DFS) (18.7 % vs. 33.5 %) and 5-year DFS (5.3 % vs. 30.5 %) (p = 0.006).

This article is published with open access Abstract Short-term memory dysfunction is a key early feature of Alzheimer’s disease (AD). Psychiatric patients may be at higher risk for memory dysfunction and subsequent AD due to the negative effects of stress and depression on the brain. We carried out longitudinal within-subject studies in male and female psychiatric patients to discover blood gene expression biomarkers that track short term memory as measured by the retention measure in the Hopkins Verbal Learning Test. These biomarkers were subsequently prioritized with a convergent functional genomics approach using previous evidence in the field implicating them in AD. The top candidate biomarkers were then tested in an independent cohort for ability to predict state short-term memory, 1234567890();,: 1234567890();,: and trait future positive neuropsychological testing for cognitive impairment. The best overall evidence was for a series of new, as well as some previously known genes, which are now newly shown to have functional evidence in humans as blood biomarkers: RAB7A, NPC2, TGFB1, GAP43, ARSB, PER1, GUSB, and MAPT.

  • Transcriptomic and Computational Analysis Identified LPA Metabolism
    www.nature.com/scientificreports OPEN Transcriptomic and computational analysis identifed LPA metabolism, KLHL14 and KCNE3 as novel regulators of Epithelial- Mesenchymal Transition V. Di Lollo1,2,3*, A. Canciello 1,3*, M. Orsini2, N. Bernabò 1, M. Ancora2, M. Di Federico2, V. Curini2, M. Mattioli1, V. Russo1, A. Mauro1, C. Cammà2 & B. Barboni 1 Epithelial-mesenchymal transition (EMT) is a complex biological program between physiology and pathology. Here, amniotic epithelial cells (AEC) were used as in vitro model of transiently inducible EMT in order to evaluate the transcriptional insights underlying this process. Therefore, RNA-seq was used to identify the diferentially expressed genes and enrichment analyses were carried out to assess the intracellular pathways involved. As a result, molecules exclusively expressed in AEC that experienced EMT (GSTA1-1 and GSTM3) or when this process is inhibited (KLHL14 and KCNE3) were identifed. Lastly, the network theory was used to obtain a computational model able to recognize putative controller genes involved in the induction and in the prevention of EMT. The results suggested an opposite role of lysophosphatidic acid (LPA) synthesis and degradation enzymes in the regulation of EMT process. In conclusion, these molecules may represent novel EMT regulators and also targets for developing new therapeutic strategies. Epithelial-mesenchymal transition (EMT) is a complex biological process. Although intracellular pathways lead- ing to the trans-diferentiation of epithelial into fbroblastic-like cells are known, several molecular mechanisms still remain to be clarifed despite the clinical urgency of the issue1. At the present, EMT is recognized to play an essential role in driving three diferent biological events: (1) type 1 EMT during embryo development, (2) type 2 in the fbrotic process, wound healing and tissue regeneration while (3) type 3 during metastatic process2.
