We present a procedure for the determination of the interaction potential from the knowledge of the radial pair distribution function. The method, realized inside an inverse Monte Carlo simulation scheme, is based on the application of the maximum entropy principle of information theory and the interaction potential emerges as the asymptotic expression of the transition probability. Results obtained for high density monoatomic fluids are very satisfactory and provide an accurate extraction of the potential, despite a modest computational effort.

Evidence indicates that transposable elements (TEs) can contribute to the evolution of new traits, with some TEs acting as deleterious elements while others are repurposed for beneficial roles in evolution. In mammals, some KRAB-ZNF proteins can serve as a key defense mechanism to repress TEs, offering genomic protection. Notably, the family of KRAB-ZNF genes evolves rapidly and exhibits diverse expression patterns in primate brains, where some TEs, including autonomous LINE-1 and non-autonomous Alu and SVA elements, remain mobile.

Importance: Increasingly, strategies to systematically detect melanomas invoke targeted approaches, whereby those at highest risk are prioritized for skin screening. Many tools exist to predict future melanoma risk, but most have limited accuracy and are potentially biased.
Objectives: To develop an improved melanoma risk prediction tool for invasive melanoma.

Transcription initiation factor TFIID subunit 1 (TAF1) is a pivotal component of the TFIID complex, critical for RNA polymerase II-mediated transcription initiation. However, the molecular basis by which TAF1 recognizes and associates with chromatin remains incompletely understood. Here, we report that the tandem bromodomain module of TAF1 engages nucleosomal DNA through a distinct positively charged surface patch on the first bromodomain (BD1).

Background And Aims: Liver metastasis significantly contributes to poor survival in patients with colorectal cancer (CRC), posing therapeutic challenges due to limited understanding of its mechanisms. We aimed to identify a potential target critical for CRC liver metastasis.
Methods: We analyzed the Gene Expression Omnibus (GEO) and the Cancer Genome Atlas (TCGA) databases and identified EphrinA3 (EFNA3) as a potential clinically relevant target.

Acute Myeloid Leukemia (AML) patient-derived Mesenchymal Stem Cells (MSCs) behave differently than normal ones, creating a more protective environment for leukemia cells, making relapse harder to prevent. This study aimed to identify prognostic biomarkers and elucidate relevant biological pathways in AML by leveraging microarray data and advanced bioinformatics techniques. We retrieved the GSE122917 dataset from the NCBI Gene Expression Omnibus and performed differential expression analysis (DEA) within R Studio to identify differentially expressed genes (DEGs) among healthy donors, newly diagnosed AML patients, and relapsed AML patients.
