A point mutation of zebrafish c-cbl gene in the ring finger domain produces a phenotype mimicking human myeloproliferative disease.

Controlled self-renewal and differentiation of hematopoietic stem/progenitor cells (HSPCs) are critical for vertebrate development and survival. These processes are tightly regulated by the transcription factors, signaling molecules and epigenetic factors. Impaired regulations of their function could result in hematological malignancies.

A cytosolic heat shock protein 90 and cochaperone CDC37 complex is required for RIP3 activation during necroptosis.

Receptor-interacting protein kinase 3, RIP3, and a pseudokinase mixed lineage kinase-domain like protein, MLKL, constitute the core components of the necroptosis pathway, which causes programmed necrotic death in mammalian cells. Latent RIP3 in the cytosol is activated by several upstream signals including the related kinase RIP1, which transduces signals from the tumor necrosis factor (TNF) family of cytokines. We report here that RIP3 activation following the induction of necroptosis requires the activity of an HSP90 and CDC37 cochaperone complex.

NOXIN as a cofactor of DNA polymerase-primase complex could promote hepatocellular carcinoma.

Oncogene activation or inactivation of tumor suppressor genes are crucial to tumor initiation and progression. DNA copy number amplification is one of many mechanisms that activate oncogenes in many tumors, including hepatocellular carcinoma (HCC). Although it has been known that some oncogenes such as c-myc amplification is involved in HCC pathogenesis, more oncogenes with DNA copy amplification contribute to HCC initiation and progression remain to be characterized.
