  • Numerous Trp53 KO mice containing large deletions of the Trp53 gene have been produced to investigate the role of Trp53 during the developmental process or tumor formation in mammals. (biomedcentral.com)
  • At 15 to 25 weeks of age, the homozygote variants of these mice were found to be dramatically susceptible to the development of multiple tumor types, and malignant lymphoma and sarcomas were frequently observed in the thymus and major visceral organs of these animals [ 9 ]. (biomedcentral.com)
  • Similar tumors were also observed in KO mice having the exon 2 or exon 2-6 deletion in C57BL/6 mice. (biomedcentral.com)
  • We analyze brain CUX1 expression and susceptibility to epilepsy in Cux1 +/− mice. (nature.com)
  • In Cux1 +/ − mice, we found delayed growth, histologically normal brains, and increased susceptibility to seizures. (nature.com)
  • EGR-1, together with TET1, is employed in programming the distribution of methylation sites on brain DNA during brain development, in learning and in long-term neuronal plasticity . (wikipedia.org)
  • Because it plays a critical role in the development of plasticity of the brain, methylation of BDNF takes a toll on brain health and resilience. (psychiatryredefined.org)
  • But the potential role of miR-1908 in the carcinogenesis and tumor development of glioblastoma is unknown. (biomedcentral.com)
  • Approximately 40% of patients who develop metastatic disease have tumour(s) confined to the liver, which has driven interest in regional therapies that target the liver [ 4 ]. (biomedcentral.com)
  • Patients with all other investigated tumors, however, had low levels of serum EGFL6 with mean concentration less than 240 pg/ml. (omicsdi.org)
  • BDNF levels are diminished in the brain and serum of Alzheimer's patients. (psychiatryredefined.org)
  • For the first time, microscopically identical tumors from different patients are shown to be genetically distinct. (hum-molgen.org)
  • Upon binding, this complex translocates to the cytoplasm, where it interacts with TGF-beta receptor type-1 (TGFBR1), leading to the degradation of both the encoded protein and TGFBR1. (cancerindex.org)
  • The heterodimeric TSC complex negatively regulates mTORC1 activity via the GTPase activity of TSC2, towards the small G-protein RHEB (Ras homologue enriched in brain) [ 5 ]. (springer.com)
  • GBM can extensively infiltrate normal brain tissue, making surgical resection almost impossible, and postoperative recurrence is common [2]. (scirp.org)
  • Some cancerous tumors can invade surrounding tissue and spread to other parts of the body. (medlineplus.gov)
  • The human EGR-1 protein contains (in its unprocessed form) 543 amino acids with a molecular weight of 57.5 kDa , and the gene is located on the chromosome 5 . (wikipedia.org)
  • While not completely understood, MyoD is now thought to function as a major myogenesis controller in an on/off switch association mediated by KAP1 (KRAB [Krüppel-like associated box]-associated protein 1) phosphorylation. (wikipedia.org)
