None:
KIAA1429, a core component of the m6A methyltransferase complex, is upregulated in clear cell renal cell carcinoma (ccRCC) and is associated with poor survival rates. Functional assays and in vivo models demonstrate that genetic depletion of KIAA1429 markedly inhibits tumor growth, as well as cancer cell proliferation, migration, and invasion. Mechanistically, KIAA1429 directly binds to the 3' untranslated region (3' UTR) of MYC mRNA and catalyzes site-specific m6A methylation, thereby enhancing transcript stability and augmenting MYC protein expression. Collectively, these findings identify KIAA1429 as a critical m6A-dependent post-transcriptional regulator of MYC and nominate the KIAA1429-MYC regulatory axis as a promising therapeutic target in ccRCC.

The Retinoblastoma Gene
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
