This study investigates the mechanism by which MALAT1 dysregulation contributes to the pathogenesis of idiopathic non-obstructive azoospermia (iNOA). We analyzed MALAT1 levels in two gene expression profiling datasets comprising patients with obstructive azoospermia (OA) who have normal spermatogenesis and 13 patients with iNOA. The dysregulation of MALAT1 along with the expression levels of its negatively correlated genes were confirmed in a larger cohort of 24 OA patients and 38 iNOA patients. We examined the effects of MALAT1 overexpression in primary human spermatogonial stem cells (SSCs) and Sertoli cells. Additionally, we assessed DNA methylation, as well as levels of H3K27me3 and H3K27Ac level near the etv5 promoter region using ChIP-qPCR. We observed that MALAT1 was overexpressed in testes of iNOA patients with its levels negatively correlating with six spermatogenesis related genes and positively correlated with three others. Overexpression of MALAT1 in SSCs repressed proliferation and induced apoptosis while also suppressing ETS variant transcription factor 5 (ETV5) expression by promoting H3K27 tri-methylation of the ETV5 promoter. Overexpression of MALAT1 in Sertoli cells did not induce apoptosis but impaired their cell supporting function.

This study elucidates the mechanisms of the m<sup>6</sup>A landscape and the specific roles of m<sup>6</sup>A regulators in hematopoietic cells of elderly AML patients. Notably, fat mass and obesity-associated protein (FTO) was found to be upregulated in hematopoietic stem cells (HSCs), myeloid cells, and T-cells, where it inhibits their differentiation via the WNT signaling pathway. Additionally, elevated YT521-B homology domain family proteins 2 (YTHDF2) expression in erythrocytes was observed to negatively regulate differentiation through oxidative phosphorylation, resulting in leukocyte activation. Moreover, IGF2BP2 was significantly upregulated in myeloid cells, contributing to an aberrant chromosomal region and disrupted oxidative phosphorylation. m<sup>6</sup>A regulators were shown to induce abnormal cell-cell communication within hematopoietic cells, mediating ligand-receptor interactions across various cell types through the HMGB1-mediated pathway, thereby promoting AML progression.

This literature review explores the advancements made from 1979 to 2024 in understanding the regulatory networks of antibiotic resistance genes in Pseudomonas aeruginosa, with a particular focus on the molecular underpinnings of these resistance mechanisms. The review highlights four main pathways involved in drug resistance: reducing outer membrane permeability, enhancing active efflux systems, producing antibiotic-inactivating enzymes, and forming biofilms. These pathways are intricately regulated by a combination of genetic regulation, transcriptional regulators, two-component signal transduction, DNA methylation, and small RNA molecules. Through an in-depth analysis and synthesis of existing literature, we identify key regulatory elements mexT, ampR, and argR as potential targets for novel antimicrobial strategies. A profound understanding of the core control nodes of drug resistance offers a new perspective for therapeutic intervention, suggesting that modulating these elements could potentially reverse resistance and restore bacterial susceptibility to antibiotics.
