Histone proteins compact and stabilize the genomes of Eukarya and Archaea. By forming nucleosome(-like) structures they restrict access of DNA-binding transcription regulators to cis-regulatory DNA elements. Dynamic competition between histones and transcription factors is facilitated by different classes of proteins including ATP-dependent remodeling enzymes that control assembly, access, and editing of chromatin. Here, we summarize the knowledge on dynamics underlying transcriptional regulation across the domains of life with a focus on ATP-dependent enzymes in chromatin structure or in TATA-binding protein activity. These insights suggest directions for future studies on the evolution of transcription regulation and chromatin dynamics.

Central nervous system neuroblastoma with FOXR2 activation (NB-FOXR2) is a high-grade tumor of the brain hemispheres and a newly identified molecular entity. Tumors express dual neuronal and glial markers, leading to frequent misdiagnoses, and limited information exists on the role of FOXR2 in their genesis. To identify their cellular origins, we profiled the transcriptomes of NB-FOXR2 tumors at the bulk and single-cell levels and integrated these profiles with large single-cell references of the normal brain.

Article Synopsis
  • * When lncRNAs are dysregulated, they can either promote cancer as oncogenes or inhibit it as tumor suppressors, affecting tumor progression and characteristics like metastasis and chemoresistance.
  • * The review emphasizes the need to understand lncRNAs' roles in cancer to develop new therapeutic strategies and enhance precision medicine approaches in treating cancer patients.

Background: Breast cancer (BC) is the most common malignant tumor in women worldwide, and further elucidation of the molecular mechanisms involved in BC pathogenesis is essential to improve the prognosis of BC patients. RNA Binding Motif Protein 8 A (RBM8A), with high affinity to a myriad of RNA transcripts, has been shown to play a crucial role in genesis and progression of multiple cancers. We attempted to explore its functional significance and molecular mechanisms in BC.

Article Synopsis
  • ATAC-seq is a technique used to study chromatin accessibility, which helps researchers understand gene regulation at both the cell population and single-cell levels.
  • Comprehensive analysis of ATAC-seq data requires navigating a sequence of complex steps and selecting appropriate parameters, which can be challenging for researchers without bioinformatics expertise.
  • Cloud ATAC is an open-source, cloud-based framework designed to simplify ATAC-seq analysis, leveraging Google Cloud for computational resources and Jupyter Notebook for interactive learning, with publicly available source codes and learning materials.
