What's a GeneRIF?

Downregulation of the PAR expression increases the Bax/Bcl-2 ratio and Bax expression, and thus induces the G2-M phase arrest and apoptosis of PC3 cells.
Title: [Downregulation of PAR expression induces the apoptosis of human prostate cancer PC3 cells and increases the Bcl-2/Bax ratio].
The JTB structure has a distant relationship to the midkine/pleiotrophin fold, particularly in the conservation of distinctive disulfide bridge patterns.
Title: The structure of the extracellular domain of the jumping translocation breakpoint protein reveals a variation of the midkine fold.
Due to its involvement in cell cycle and its overexpression in several human cancers PAR could represent an attractive target for therapeutic intervention.
Title: PAR, a protein involved in the cell cycle, is functionally related to chromosomal passenger proteins.
Overexpression of JTB conferred resistance to apoptosis induced by ultraviolet radiation
Title: Interacting with HBsAg compromises resistance of jumping translocation breakpoint protein to ultraviolet radiation-induced apoptosis in 293FT cells.
Among ten hepatocellular carcinoma cases with amplicon 1q21-q22, significant gene expression level of JTB, SHC1, CCT3 and COPA in the tumors than the paired adjacent non-malignant liver tissues.
Title: Positional mapping for amplified DNA sequences on 1q21-q22 in hepatocellular carcinoma indicates candidate genes over-expression.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
