Silencing of maternally expressed RNAs in Dlk1-Dio3 domain causes fatal vascular injury in the fetal liver.

Cell Mol Life Sci

October 2024

School of Life Science and Technology, State Key Laboratory of Urban Water Resource and Environment, Harbin Institute of Technology, Harbin, 150001, China.

Article Synopsis
  • The Dlk1-Dio3 domain in mammals contains important genetic elements, including lncRNAs, mRNAs, and a large miRNA cluster, and its deletion affects embryonic development, leading to death.
  • Researchers created a mouse model to investigate how silencing maternally expressed RNAs in this domain results in apoptosis, specifically affecting the liver, ultimately causing fetal hemorrhage.
  • The study reveals that the silencing of these RNAs activates paternally expressed genes, and this process—rather than the differential methylation regions—leads to embryonic death due to liver damage.

AlphaCRV: a pipeline for identifying accurate binder topologies in mass-modeling with AlphaFold.

Bioinform Adv

September 2024

Biological and Environmental Science and Engineering Division, Computational Biology Research Center, King Abdullah University of Science and Technology, Thuwal 23955-6900, Kingdom of Saudi Arabia.

Motivation: The speed and accuracy of deep learning-based structure prediction algorithms make it now possible to perform in silico "pull-downs" to identify protein-protein interactions on a proteome-wide scale. However, on such a large scale, existing scoring algorithms are often insufficient to discriminate biologically relevant interactions from false positives.

Results: Here, we introduce AlphaCRV, a Python package that helps identify correct interactors in a one-against-many AlphaFold screen by clustering, ranking, and visualizing conserved binding topologies, based on protein sequence and fold.

P-NADs: UX-based nobody degraders for ubiquitin-independent degradation of target proteins.

Heliyon

July 2024

Biological and Environmental Science and Engineering Division, Computational Biology Research Center, King Abdullah University of Science and Technology (KAUST), Thuwal, 23955-6900, Kingdom of Saudi Arabia.

Targeted protein degradation (TPD) allows cells to maintain a functional proteome and to rapidly adapt to changing conditions. Methods that repurpose TPD for the deactivation of specific proteins have demonstrated significant potential in therapeutic and research applications. Most of these methods are based on proteolysis targeting chimaeras (PROTACs) which link the protein target to an E3 ubiquitin ligase, resulting in the ubiquitin-based degradation of the target protein.

Neurogenetics

July 2024

Biological and Environmental Science and Engineering Division, Computational Biology Research Center, King Abdullah University of Science and Technology (KAUST), Thuwal, 23955-6900, Kingdom of Saudi Arabia.

Primary microcephaly is a rare neurogenic and genetically heterogeneous disorder characterized by significant brain size reduction that results in numerous neurodevelopmental disorders (NDD) problems, including mild to severe intellectual disability (ID), global developmental delay (GDD), seizures and other congenital malformations. This disorder can arise from a mutation in genes involved in various biological pathways, including those within the brain. We characterized a recessive neurological disorder observed in nine young adults from five independent consanguineous Pakistani families.

Background: Being the most widely used biomarker for immunotherapy, the microsatellite status has limitations in identifying all patients who benefit in clinical practice. It is essential to identify additional biomarkers to guide immunotherapy. Aberrant DNA methylation is consistently associated with changes in the anti-tumor immune response, which can promote tumor progression.

N-acetylcytidine of Nop2 mRNA is required for the transition of morula-to-blastocyst.

Cell Mol Life Sci

September 2023

Developmental Biology Laboratory, School of Life Science and Technology, Harbin Institute of Technology, Harbin, 150001, China.

N-acetyltransferase 10 (NAT10)-mediated N-acetylcytidine (acC) modification is crucial for mRNA stability and translation efficiency, yet the underlying function in mammalian preimplantation embryos remains unclear. Here, we characterized the acC modification landscape in mouse early embryos and found that the majority of embryos deficient in acC writer-NAT10 failed to develop into normal blastocysts. Through single-cell sequencing, RNA-seq, acetylated RNA immunoprecipitation combined with PCR (acRIP-PCR), and embryonic phenotype monitoring, Nop2 was screened as a target gene of Nat10.

  • Autosomal recessive mutations in the GAF-A domain cause infantile onset chorea and developmental delays, whereas dominant mutations in the GAF-B domain lead to childhood onset chorea but with typical cognitive development.
  • In a studied family with PDE10A mutations, individuals exhibited recessive symptoms alongside a bi-allelic GAF-B mutation, indicating unique mechanisms affecting PDE10A activity and enhancing our understanding of PDE10A-related movement disorders.
