Breakthrough for a DNA break-preventer

Clinical importance of DNA repair in sporadic colorectal cancer

Colorectal cancer (CRC) is the third major cause of cancer-related deaths worldwide. However, despite the scientific efforts to provide a molecular classification to improve CRC clinical practice management, prognosis and therapeutic decision are still strongly dependent on the TNM staging system. Mismatch repair system deficiencies can occur in many organs, but it is mainly a hallmark of CRC influencing clinical outcomes and response to therapy. This review will discuss the effect of the modulation of other DNA repair pathways (direct, excision and double strand break repairs) in the clinical and pathological aspects of colorectal cancer and its potential as prognostic and predictive biomarkers.

Catalytic transfer hydrogenation and anticancer activity of arene–ruthenium compounds incorporating bi-dentate precursors

A series of arene–Ru compounds were synthesized and their catalytic transfer hydrogenation and anticancer activity towards human hormone-refractory prostate cancer were investigated.
