USP49 potently stabilizes APOBEC3G protein by removing ubiquitin and inhibits HIV-1 replication

eLife, 2019
The antiviral activity of host factor apolipoprotein B mRNA editing enzyme catalytic polypeptide-like 3G (APOBEC3G, A3G) and its degradation mediated by human immunodeficiency virus type 1 (HIV-1) Vif protein are important topics.

Targeting USP7-Mediated Deubiquitination of MDM2/MDMX-p53 Pathway for Cancer Therapy: Are We There Yet?

Frontiers in Cell and Developmental Biology, 2020
The p53 tumor suppressor protein and its major negative regulators MDM2 and MDMX oncoproteins form the MDM2/MDMX-p53 circuitry, which plays critical roles in regulating cancer cell growth, proliferation, cell cycle progression, apoptosis, senescence ...

An APC/C inhibitor stabilizes cyclin B1 by prematurely terminating ubiquitination [PDF]

, 2012
The Anaphase-Promoting Complex/Cyclosome (APC) is a ubiquitin ligase required for exit from mitosis. We previously showed that Tosyl Arginine Methyl Ester (TAME) inhibits APC-dependent proteolysis by competing with the C-terminal IR-tail of the APC ...

TrkA abundance is increased in cutaneous nerves in bortezomib‐induced neuropathy

Brain Pathology, EarlyView.
Cutaneous nerves in bortezomib‐induced peripheral neuropathy (BIPN) show reduced nerve fiber density, increased TrkA expression, and enhanced dermal angiogenesis, highlighting a pathological switch in NGF/TrkA signaling that may contribute to nerve damage and pain. Abstract Tropomyosin receptor kinase A (TrkA), a high‐affinity receptor for nerve growth

Regulation of junction dynamics in the testis--transcriptional and post-translational regulations of cell junction proteins [PDF]

, 2006
Cell junctions are the sites at which cells attach to the neighboring cells. They do not only maintain tissue integrity, their turnover also plays a crucial role in cell development and morphogenesis. In the testis, tight junctions and adherens junctions

Mechanism and function of deubiquitinating enzymes

Biochimica et Biophysica Acta (BBA) - Molecular Cell Research, 2004
Attachment of ubiquitin to proteins is a crucial step in many cellular regulatory mechanisms and contributes to numerous biological processes, including embryonic development, the cell cycle, growth control, and prevention of neurodegeneration. In these diverse regulatory settings, the most widespread mechanism of ubiquitin action is probably in the ...

Mitochondrial Transfer in the Tumor Microenvironment

Cancer Science, EarlyView.
Mitochondria are actively exchanged among tumor, immune, stromal, and neuronal cells within the tumor microenvironment. Such transfer rewires tumor metabolism, promotes immune evasion, and drives therapy resistance. Targeting mitochondrial transfer or harnessing mitochondrial transplantation represents a promising strategy to restore antitumor immunity

USP18 mediates high glucose‐induced cardiomyocyte injury by regulating the JAK/STAT signaling pathway through stabilizing FOXC2 expression

Journal of Diabetes Investigation, EarlyView.
USP18 upregulation stabilizes FOXC2 expression by deubiquitination to inactivate the JAK2/STAT3 pathway, thereby inhibiting HG‐induced NMVM apoptosis, inflammation, oxidative stress, and fibrosis. ABSTRACT Background Cardiomyopathy is one of the complications of diabetes, among which myocardial fibrosis is the most typical feature.

Cezanne (OTUD7B) regulates HIF-1α homeostasis in a proteasome-independent manner [PDF]

, 2014
The transcription factor HIF-1α is essential for cells to rapidly adapt to low oxygen levels (hypoxia). HIF-1α is frequently deregulated in cancer and correlates with poor patient prognosis.

Canonical and non‐canonical functions of proteins regulating mitochondrial dynamics in mammalian physiology

The Journal of Physiology, EarlyView.
Abstract figure legend Mitochondria are highly dynamic organelles that continuously remodel their architecture through coordinated cycles of fusion and fission. This review examines the four key GTPases that orchestrate mitochondrial dynamics in mammals: MFN1, MFN2, OPA1, and DRP1.
