Gene RIF (9)

26877821 up-regulated in metastatic castration-resistant prostate cancer and elevated expression correlates with poor clinical outcome
26431491 Data show that basal-like subgroup was enriched for aggressive tumors and somatic mutations in trithorax-group genes and it overexpressed polycomb genes EZH2 and CBX2.
25569159 CBX2 role in the sex development cascade is to stimulate the male pathway and concurrently inhibit the female pathway.
25225902 CBX2 upregulation and amplification significantly correlated with metastatic progression and lower overall survival in many cancer types, particularly those of the breast
23219007 This study does not support CBX2 gene disruption as a common cause of gonadal gonadal disorders of sex development.
22632162 Both HIV-1 Tat 47-59 and FITC-labeled Tat 47-59 peptides downregulate gene expression of chromobox homolog 2 (CBX2) in U-937 macrophages
22419124 Two distinct mechanisms are involved in CBX2-mediated gene silencing. The short CBX2-2 isoform would repress the transcription in a PRC1-independent fashion, whereas gene repression by the long CBX2-1 isoform is mediated by the PRC1 protein complex.
22009739 CDYL functions as a molecular bridge between PRC2 and the repressive chromatin mark H3K27me3, forming a positive feedback loop to facilitate the establishment and propagation of H3K27me3 modifications along the chromatin
19107218 hPc2 serves as a SUMO E3 ligase for cystathionine beta-synthase, increasing the efficiency of sumoylation.
