How Combining Structurally Different RAF Inhibitors Can Open New Strides In Targeted Melanoma Therapy - Science Trends

For this, they set out to generate a next-generation computer model of the underlying molecular signalling network which not only integrates the known protein-protein interaction and network architecture, but also includes the thermodynamics and ...

Nuclear envelope assembly defects link mitotic errors to chromothripsis - Nature.com

Because cells release from the mitotic block with only partial synchrony, we could identify cells in which aurora B was inhibited at each stage between metaphase and telophase. Unexpectedly, inhibition of aurora B restored non-core protein assembly to ...

Does LRRK2 Sweep α-Synuclein from the Cell? - Alzforum

In the September 12 Proceedings of the National Academy of Sciences, researchers led by Takeshi Iwatsubo at the University of Tokyo reported that protein accumulation in lysosomes leads LRRK2 to swoop in and prod these organelles to disgorge their ...

The inositol phosphatase SHIP2 enables sustained ERK activation downstream of FGF receptors by recruiting Src ... - Science

We previously identified the inositol phosphatase SHIP2 (also known as INPPL1) as an FGFR-interacting protein and a target of the tyrosine kinase activities of FGFR1, FGFR3, and FGFR4. We report that loss of SHIP2 converted FGF-mediated sustained ERK ...

Caspase-2 Enzyme Inhibition Shows Promise for Ameliorating Fatty Liver Disease - Laboratory Equipment

Researchers at University of California San Diego School of Medicine have discovered using mice and human clinical specimens, that caspase-2, a protein-cleaving enzyme, is a critical driver of non-alcoholic steatohepatitis (NASH), a chronic and ...

ACE Inhibitors May Protect Nerve Cells from Damage That Harms Cognition, Early Lupus Study Reports - Lupus News Today

Patients with widespread manifestations of lupus in the brain often show evidence of particular antibodies, called DNRAbs, that target both DNA and a key brain protein called NMDAR. The findings led researchers to hypothesize that DNRAbs might be ...

Preventing Transportation of Mutant Protein Can Inhibit Growth of Leukemic Cells - AJMC.com Managed Markets Network

Preventing NPM1c from leaving the nucleus and moving into the cytoplasm—using either CRISPR or a cancer drug—can inhibit leukemic cell growth. The researchers found in culture dishes that blocking the transportation of the mutant protein caused ...

Aptamer inhibits TB bacteria entry into cells - The Hindu

Despite being an attractive drug target, designing inhibitors against HupB has been largely unsuccessful as the full length crystal structure of the protein is not known due to the disordered nature of the end portion of the protein (C-terminal). As a ...

Two unrelated studies result in discovery of CRISPR-Cas12a inhibitors - Phys.Org

While bacteria harboring CRISPR-Cas9 or CRISPR-Cas3 adaptive immune systems sometimes acquire mobile genetic elements encoding anti-CRISPR proteins that inhibit Cas9, Cas3, or the DNA-binding Cascade complex, no such inhibitors have been ...

Researchers Discover 15 New CRISPR Inhibitors - GenomeWeb

While bacteria harboring Cas9 or Cas3 adaptive immune systems sometimes acquire genetic elements that encode Cas9, Cas3, or Cascade complex anti-CRISPR (Acr) proteins, this is the first instance in which inhibitors have been found for Cas12a, the ...

China's Beigene Teams up With Springworks to Target Advanced Solid Tumors - BioSpace (press release) (blog)

Targeting nucleotide exchange to inhibit constitutively active G protein α subunits in cancer cells - Science

Activating mutations in G protein α subunits cause various diseases, including some forms of uveal melanoma (UM), an aggressive eye cancer. Onken et al. found that the plant-derived compound FR900359 blocked the growth of Gα-mutant UM cells in ...

Firazyr Lowers Attack Duration, But Increases Healthcare Costs in Angioedema Patients - Angioedema News

Patients with hereditary angioedema caused by deficiencies in the complement C1-inhibitor protein experience symptomatic relief and remission with the use of on-demand treatments, according to an Italian study. Firazyr (icatibant), an agonist of the ...

An orthogonal proteomic survey uncovers novel Zika virus host factors - Nature.com

To comprehensively understand how ZIKV affects neuronal cells, we performed an unbiased proteomic survey to identify cellular proteins and associated complexes that interact with each of the ten ZIKV proteins expressed in human SK-N-BE2 neuroblastoma ...

Let 'Er RIP: ALS/FTD Variant Plus Aging Unleash Deadly Kinase - Alzforum

Living up to its ominous acronym, RIPK1, the receptor-interacting serine/threonine-protein kinase 1 unleashes powerful signaling cascades that can fell cells within hours. Thankfully, several inhibitors normally keep these deadly doings in check. But ...

Chemical disruption of the pyroptotic pore-forming protein gasdermin D inhibits inflammatory cell death and sepsis - Science

Here, we identify necrosulfonamide as a direct chemical inhibitor of gasdermin D, the pyroptotic pore-forming protein, which binds directly to gasdermin D to inhibit pyroptosis. Pharmacologic inhibition of pyroptotic cell death by necrosulfonamide is ...

ADVM-053 Receives Orphan Drug Designation for Treatment of Hereditary Angioedema - Rare Disease Report

Hereditary angioedema type I and type II are caused by mutations in the SERPING1 gene, which plays a critical role in creating the C1 inhibitor protein that is essential for controlling inflammation. The mutations that cause hereditary angioedema type ...

MEK inhibitors for the treatment of NRAS mutant melanoma - Dove Medical Press

Treatment options have expanded beyond high-dose interleukin 2 and adoptive T-cell therapy to include inhibitors of immune checkpoints programmed death 1 (PD-1) and cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) and small molecular inhibitors ...

The inhibitor protein is situated in the mitochondrial matrix and protects the cell against rapid ATP hydrolysis during momentary ischaemia. In oxygen absence, the pH of the matrix drops. This causes IP to become protonated and change its conformation to one that can bind to the F1Fo synthetase and stops it thereby preventing it from moving in a backwards direction and hydrolyze ATP instead of make it. When oxygen is finally incorporated into the system, the pH rises and IP is deprotonated. IP dissociates from the F1Fo synthetase and allows it to resume its ATP synthesis.
