Researchers found that two p53 isoforms, Δ133p53 and p53β, play a crucial role in regulating senescence. The study suggests that altering the ratio of these isoforms may be an effective therapeutic strategy for treating immunosenescence disorders.
A study published in the Journal of Clinical Investigation found that two p53 isoforms regulate aging- and tumor-associated replicative senescence in T lymphocytes. Additionally, a new gene therapy approach may not require immunosuppression, as regulatory T cells promote long-term expression.
Researchers have been studying the impact of an isoform on human resistance to fatigue, which occurs when muscles can't continue contracting. The study found that this isoform provides a 'turbocharger effect,' speeding up muscle function during exercise.
A new study by Ohio State University researchers found that replication-dependent histone isoforms have distinct cellular functions and play a role in cancer development. The study showed that changes in expression of these isoforms can influence cell proliferation and tumor growth.
Researchers discovered that knocking out the ∆N isoforms of genes p63 and p73 can restore tumor suppression in mice lacking p53. This allows other family members to compensate for the loss of p53, potentially leading to new cancer treatments.
Researchers at the University of Kentucky found that p38beta MAPK has no effect on brain-cell cultures or mouse brains in terms of inflammation and neurotoxicity. This suggests that development of p38-inhibitor drugs may focus on targeting p38alpha instead of retaining p38beta inhibitory activity.
Researchers use antisense technology to target cancer cell metabolic process, killing cancer cells by blocking production of pyruvate kinase splice-variant. The approach shows therapeutic promise in treating various types of cancer.
BIDMC researchers create novel antibodies that distinguish between healthy and disease-causing tau isoforms, raising the possibility of an immunization strategy for early-stage Alzheimer's diagnosis and treatment. The findings also suggest that targeting only the disease-causing isoform could prevent or slow disease progression.
Researchers at The Wistar Institute discovered how cells create alternate versions of mRNA transcripts by altering how they read DNA. This leads to alternative forms of proteins, which can be used in different developmental stages or cell types.
A new study reveals that certain types of chronic pain may be caused by signals from the skin itself, rather than damage to nerves within the skin. Skin cells generate increased amounts of a lesser-known 'beta' isoform of CGRP, which may be sending pain signals to remaining sensory nerve fibers in the skin.
Researchers at UMass Medical School have discovered a new DAF-16 isoform that collaborates with other isoforms to regulate longevity and stress response in C. elegans. The newly found isoform, DAF-16d/f, works in concert with DAF-16a to promote organismal life span.
A study by Rensselaer Polytechnic Institute professor Peter M. Tessier has found that an organic compound in red wine, resveratrol, can neutralize the toxic effects of proteins linked to Alzheimer's disease. The research provides insights into the structural differences between toxic and benign peptide arrangements.
Researchers at Stanford University School of Medicine discovered that restricting genetic splicing variants decreases as embryonic stem cells differentiate into specialized cells. This finding provides new insights into the complex process of neural differentiation and potential implications for human development.
A study at Cold Spring Harbor Laboratory has identified three molecular factors that contribute to high levels of PK-M2 in cancer cells, which promotes rapid cell proliferation and tumor growth. The researchers found that forcing a reduction in the levels of these factors could reverse the Warburg effect and restore normal metabolism.
MDC researchers have elucidated a molecular mechanism that regulates the equilibrium between bone formation and bone resorption. They found that two different forms of a gene switch – LAP and LIP – determine this process. The study suggests that an imbalance in the ratio between these two isoforms may play a role in osteoporosis.
Researchers have identified a previously unknown form of potassium channel, Isoform 3.1, implicated in schizophrenia and linked to abnormal brain activity. Inhibiting this protein may correct disorganized brain activity without cardiac side effects associated with existing antipsychotic medications.
Research team investigates effect of TGF-beta 1 on intestinal fibroblast migration and differentiation. Short-term incubation enhances migration, while long-term treatment reduces it, with increased FN production.
Scientists have found that nearly all human genes, about 94 percent, generate more than one form of their protein products through alternative splicing. The phenomenon varies significantly between tissues, with mRNA expression dependent on the tissue where the gene is expressed.
Research detects ER-alpha and PR isoforms in Mongolian gerbil stomach, but their regulation by E2 and P4 varies between tissues. The study sheds light on the mechanisms behind these receptors' roles in gastric health.
Researchers have discovered that isoforms from Novel Structure Proteins (NSPs) could be involved in apoptosis, a process of programmed cell death. The NSPs were found to interact with the protein B23, and silencing their expression led to increased cell viability but reduced apoptosis.
Researchers at the University of Montreal have established the cause of hereditary sensory and autonomic neuropathy type II, a severe disorder characterized by loss of sensation in limbs. The WNK1/HSN2 isoform has been identified as the underlying gene mutation, allowing for the development of animal models and potential pain treatments.
FGF8 promotes cell proliferation, differentiation and survival. In developing embryos, FGF8 is involved in the regulation of neural crest cell migration.
