The BRCA1-Δ11q Alternative Splice Isoform Bypasses Germline Mutations and Promotes Therapeutic Resistance to PARP Inhibition and Cisplatin.
(2016-05)
Breast and ovarian cancer patients harboring BRCA1/2 germline mutations have clinically benefitted from therapy with PARP inhibitor (PARPi) or platinum compounds, but acquired resistance limits clinical impact. In this ...
SIRT3 controls brown fat thermogenesis by deacetylation regulation of pathways upstream of UCP1.
(ELSEVIER SCIENCE BV, 2019-07-01)
OBJECTIVE: Brown adipose tissue (BAT) is important for thermoregulation in many mammals. Uncoupling protein 1 (UCP1) is the critical regulator of thermogenesis in BAT. Here we aimed to investigate the deacetylation control ...
LUBAC determines chemotherapy resistance in squamous cell lung cancer.
(ROCKEFELLER UNIV PRESS, 2019-02-04)
Lung squamous cell carcinoma (LSCC) and adenocarcinoma (LADC) are the most common lung cancer subtypes. Molecular targeted treatments have improved LADC patient survival but are largely ineffective in LSCC. The tumor ...
MEKK3 coordinates with FBW7 to regulate WDR62 stability and neurogenesis.
(PUBLIC LIBRARY SCIENCE, 2018-12-01)
Mutations of WD repeat domain 62 (WDR62) lead to autosomal recessive primary microcephaly (MCPH), and down-regulation of WDR62 expression causes the loss of neural progenitor cells (NPCs). However, how WDR62 is regulated ...
Tissue curvature and apicobasal mechanical tension imbalance instruct cancer morphogenesis.
(NATURE PUBLISHING GROUP, 2019-02-07)
Tubular epithelia are a basic building block of organs and a common site of cancer occurrence1-4. During tumorigenesis, transformed cells overproliferate and epithelial architecture is disrupted. However, the biophysical ...
The deubiquitinase USP9X regulates FBW7 stability and suppresses colorectal cancer.
(AMER SOC CLINICAL INVESTIGATION INC, 2018-04-02)
The tumor suppressor FBW7 targets oncoproteins such as c-MYC for ubiquitylation and is mutated in several human cancers. We noted that in a substantial percentage of colon cancers, FBW7 protein is undetectable despite the ...
Faecal neutrophil elastase-antiprotease balance reflects colitis severity.
(NATURE PUBLISHING GROUP, 2020-03-01)
Given the global burden of diarrheal diseases on healthcare it is surprising how little is known about the drivers of disease severity. Colitis caused by infection and inflammatory bowel disease (IBD) is characterised by ...
Transcriptomic analysis of human primary breast cancer identifies fatty acid oxidation as a target for metformin.
(NATURE PUBLISHING GROUP, 2020-01-21)
BACKGROUND: Epidemiological studies suggest that metformin may reduce the incidence of cancer in patients with diabetes and multiple late phase clinical trials assessing the potential of repurposing this drug are underway. ...
Delayed APC/C activation extends the first mitosis of mouse embryos.
(Springer Science and Business Media LLC, 2017-08-29)
The correct temporal regulation of mitosis underpins genomic stability because it ensures the alignment of chromosomes on the mitotic spindle that is required for their proper segregation to the two daughter cells. Crucially, ...
Hypoxia-induced switch in SNAT2/SLC38A2 regulation generates endocrine resistance in breast cancer.
(NATL ACAD SCIENCES, 2019-06-18)
Tumor hypoxia is associated with poor patient outcomes in estrogen receptor-α-positive (ERα+) breast cancer. Hypoxia is known to affect tumor growth by reprogramming metabolism and regulating amino acid (AA) uptake. Here, ...
