Abstract:
Strong lines of evidence have established a critical role for the homeodomain protein HOXB7 in cancer. Specifically, molecular and cellular studies have demonstrated that HOXB7 is a master regulatory gene, capable of orchestrating a variety of target molecules, resulting in the activation of several oncogenic pathways. HOXB7 overexpression correlates with clinical progression and poor outcome of cancer patients. Specific inhibition of HOXB7 is particularly relevant in cancers still lacking effective therapies, such as tamoxifen-resistant breast cancer and melanoma. Mechanistic studies are providing additional targets of therapy, and biomarker studies are further establishing its importance in early diagnosis and prognosis.

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...

Cancer-Critical Genes II: Tumor Suppressor Genes
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
