Finding novel vulnerabilities of hypomorphic BRCA1 alleles

Molecular Oncology, EarlyView.
Synthetic lethality screens performed to identify novel vulnerabilities often model complete gene loss, thereby overlooking patient‐derived hypomorphic mutations. In this study, we have performed genome‐wide CRISPR screens on BRCA1 hypomorphic mutations, showing BRCA1I26A behaves like wild‐type, while BRCA1R1699Q mimics deficiency. Furthermore, we have

Exploring the origins of neurodevelopmental proteasomopathies associated with cardiac malformations: are neural crest cells central to certain pathological mechanisms?

Frontiers in Cell and Developmental Biology
Neurodevelopmental proteasomopathies constitute a recently defined class of rare Mendelian disorders, arising from genomic alterations in proteasome-related genes.

Role of transcription factor acetylation in the regulation of metabolic homeostasis [PDF]

, 2015
Post-translational modifications (PTMs) of transcription factors play a crucial role in regulating metabolic homeostasis. These modifications include phosphorylation, methylation, acetylation, ubiquitination, SUMOylation, and O-GlcNAcylation.

Oncogenic DMTF1β promotes cancer cell motility by regulating autophagy through ULK1 stabilization

Molecular Oncology, EarlyView.
In the current study, we demonstrate that the oncogene DMTF1β regulates ULK1 stability by reducing its proteasomal degradation in cancer cells. This stabilization enables ULK1 to induce autophagy, which in turn facilitates cancer cell migration. Consequently, reduced DMTF1β levels lead to decreased autophagy and impaired cancer cell migration.

COP9 signalosome is required for adipose tissue maintenance and metabolic health

Journal of Lipid Research
Constitutive photomorphogenesis mutant 9 (COP9) signalosome (CSN) is composed of eight subunits (CSN1 through CSN8). It acts as an essential regulator of Cullin-RING-ubiquitin ligases (CRLs), which target critical cellular regulators for degradation via ...

Loss of proton‐sensing TDAG8 increases tumor progression in mouse models of colon cancer

Molecular Oncology, EarlyView.
Loss of the pH‐sensing receptor TDAG8 accelerates colorectal cancer progression in mice. Animals lacking TDAG8 expression had increased tumor growth, DNA damage, and recruitment of tumor‐associated immune cells, including macrophages, neutrophils, and monocytes.

Lipid homeostasis is essential for endoplasmic reticulum protein quality control [PDF]

, 2019
The endoplasmic reticulum (ER) is a critical organelle for protein synthesis, protein trafficking, and lipid synthesis. As such, cells have evolved a quality control system known as the ER Unfolded Protein Response (UPRER).

Structural Variations of Prions and Prion-like Proteins Associated with Neurodegeneration

Current Issues in Molecular Biology
Neurodegeneration is becoming one of the leading causes of death worldwide as the population expands and grows older. There is a growing desire to understand the mechanisms behind prion proteins as well as the prion-like proteins that make up ...

The role of insulin receptor substrate 2 in hypothalamic and β cell function [PDF]

, 2005
Insulin receptor substrate 2 (Irs2) plays complex roles in energy homeostasis. We generated mice lacking Irs2 in β cells and a population of hypothalamic neurons (RIPCreIrs2KO), in all neurons (NesCreIrs2KO), and in proopiomelanocortin neurons ...
