HLM006474 has been used as an E2 factor (E2F) inhibitor in human nasopharyngeal carcinoma hone-1 cells[1] and T. annulata-infected TBL20 cells.[2]
Ações bioquímicas/fisiológicas
HLM006474 activates p53 and induces DNA damage and apoptosis in mouse tumor models.[3]
HLM006474 is a pan-E2F transcription factor inhibitor.
HLM006474 is a pan-E2F transcription factor inhibitor. E2F s part of the CDK/Rb/E2F pathway. When phosphorylated by CDKs, the tumor suppressor retinoblastoma protein (Rb) is inactivated, releasing E2Fs and allowing cell cycle progression. HLM006474 inhibited DNA-binding of all E2F complexes and down-regulated expression of E2F4 protein. HLM006474 induced apoptosis of A375 melanoma cells and synergized with paclitaxel in lung cancer cell lines.
Osteosarcoma (OS) is characterized by TP53 mutations in humans. In mice, loss of p53 triggers OS development, and osteoprogenitor-specific p53-deleted mice are widely used to study the process of osteosarcomagenesis. However, the molecular mechanisms underlying the initiation or progression of
Melanoma is one of the most lethal cancers when it reaches a metastatic stage. Despite advancements in targeted therapies (BRAF inhibitors) or immunotherapies (anti-CTLA-4 or anti-PD1), most patients with melanoma will need additional treatment. Thus, there is an urgent need

Clinical studies suggest a positive association between malignant progression of nasopharyngeal carcinoma (NPC) and Rta, a transcription factor of Epstein-Barr virus (EBV). However, Rta induces cellular senescence in vitro. To provide an underlying mechanism integrating these clues, we adapted a concept
Intracellular pathogens have evolved intricate mechanisms to subvert host cell signaling pathways and ensure their own propagation. A lineage of the protozoan parasite genus Theileria infects bovine leukocytes and induces their uncontrolled proliferation causing a leukemia-like disease. Given the importance
Retinoblastoma, a childhood cancer, is most frequently caused by bi-allelic inactivation of RB1 gene. However, other oncogenic mutations such as MYCN amplification can induce retinoblastoma with proficient RB1. Previously, we established RB1-proficient MYCN-overexpressing retinoblastoma models both in human organoids and
