Article Abstract
The global transcriptional program of murine cytomegalovirus (MCMV), involving coding, noncoding, and antisense transcription, remains unknown. Here we report an oligonucleotide custom microarray platform capable of measuring both coding and noncoding transcription on a genome-wide scale. By profiling MCMV wild-type and immediate-early mutant strains in fibroblasts, we found rapid activation of the transcriptome by 6.5 h postinfection, with absolute dependency on ie3, but not ie1 or ie2, for genomic programming of viral gene expression. Evidence is also presented to show, for the first time, genome-wide noncoding and bidirectional transcription at late stages of MCMV infection.

Purpose: Lung cancer is currently the most common malignant tumor worldwide and one of the leading causes of cancer-related deaths, posing a serious threat to human health. MicroRNAs (miRNAs) are a class of endogenous non-coding small RNA molecules that regulate gene expression and are involved in various biological processes associated with lung cancer. Understanding the mechanisms of lung carcinogenesis and detecting disease biomarkers may enable early diagnosis of lung cancer.

Cancer-associated muscle wasting is associated with poor clinical outcomes, but its underlying biology is largely uncharted in humans. Unbiased analysis of the RNAome (coding and non-coding RNAs) with unsupervised clustering using integrative non-negative matrix factorization provides a means of identifying distinct molecular subtypes and was applied here to muscle of patients with colorectal or pancreatic cancer. Rectus abdominis biopsies from 84 patients were profiled using high-throughput next-generation sequencing.

Treatment-resistant depression (TRD) is a severe condition characterized by chronic and recurrent depressive symptoms, leading to significant morbidity and a considerable socio-economic impact. Genetic and biological studies suggest that TRD is associated with distinct biological characteristics. In this study, we analysed whole-transcriptome differences in 293 patients with major depressive disorder (MDD) to compare TRD (N = 150) vs non-TRD (N = 143) cases.

In this edition of Gene's "Editor's Corner" we summarize the complex interactions of different molecular mechanisms behind the pathogenesis of neonatal hypoxic-ischemic encephalopathy (HIE). The topic is relevant, as the therapeutic options for HIE are limited, it is important to have as much knowledge as possible about the molecular processes underlying the disease. In the recent issue of Gene (Gene 952, 2025, 149363), Wang et al.
