A team of IRCM researchers confirmed the universality of essential cellular process phosphorylation of RNA polymerase II, contradicting recent genome-wide analyses. The study provides critical insights into genetic regulation and may lead to new treatments for genetic diseases and cancer.
Researchers at Ruhr-University Bochum found that sildenafil, the active ingredient in Viagra, makes stiffened cardiac walls more elastic. The drug activates an enzyme that phosphorylates the giant protein titin, causing blood vessels to relax and improving diastolic distensibility.
A new blood test detects phosphorylated alpha-synuclein, allowing for early diagnosis of Parkinson's disease before symptoms appear. This could help patients prepare for potential neurological problems caused by the disease.
A team of researchers at the University of Texas MD Anderson Cancer Center found that pyruvate kinase M2 (PKM2) has an unexpected role in regulating cell proliferation and tumor formation in brain cancer. PKM2's ability to bind to beta-catenin in the cell nucleus is essential for its function, and its levels are correlated with brain t...
A protein called CDK1 deactivates the cancer-causing enzyme EZH2 by attaching a phosphate group, preventing cancer cell migration and invasion. This process also plays a crucial role in bone formation.
A recent study discovered that blood flow force triggers a chain reaction protecting arteries from dangerous clogs. The reaction involves the structural change of an enzyme, histone deacetylase 5 (HDAC5), influencing key genes involved in reversing atherosclerosis.
The kinase IKK phosphorylates mutated Huntingtin protein to promote its removal, but also increases neurotoxicity in later stages of the disease. This dual role highlights the complexity of IKK's function in Huntington's disease.
Researchers found that common human bacteria, specifically Porphyromas gingivalis, produce unique lipids that can enhance inflammatory responses and exacerbate autoimmune diseases like multiple sclerosis. These lipids may serve as new markers of MS disease activity and targets for therapeutic intervention.
Researchers at the University of Texas Medical Branch discovered a major virulence factor for Rift Valley fever virus that has a dual mechanism. The protein NSs promotes viral replication by attacking a host cell protein, preventing interferon beta production and allowing the virus to replicate unchecked.
The study reveals a novel anti-apoptotic signaling pathway disrupted by PINK1 mutations, suggesting a potential target for therapeutic intervention in Parkinson's disease. Increasing evidence links single-copy mutations in PINK1 to the development of later-onset PD.
Researchers discovered that phosphorylation of MeCP2 at S421 increases transcription of genes required for experience-dependent brain maturation, including BDNF. This study reveals a complex regulatory loop between BDNF and neuronal activity in regulating MeCP2 function.
Researchers found that Vax2 protein shuttles between nucleus and cytoplasm in response to Sonic hedgehog signaling molecule. In its nuclear state, Vax2 represses Pax6, allowing optic nerve development. In contrast, Pax6 regulates retinal fate. This coordination is crucial for proper eye development.
A team of scientists has discovered the crucial role of phosphorylation and recombination in the step-wise loss of cohesins during meiosis. This process is essential for accurate chromosome segregation into separate cells. The findings provide significant insights into the intricate mechanisms governing cohesin function.
Researchers found that enzyme EZH2 has two forms, one promoting oncogenesis and the other inhibiting cell growth. This discovery offers new insights into the role of EZH2 in cancer development and potentially leads to more effective treatments.
Researchers discovered a specific code that unlocks T cell activation, preventing immune cells from attacking the body's own cells. The code is: B1, C2, A1, A2, B2, C1.
