Cancer cells: How they shrink or grow larger to survive
A new study, published in the journal Science Advances and funded by The Institute of Cancer Research, is using advanced image analysis and DNA/protein examination to investigate the size regulation of melanoma cells, a type of skin cancer.
Researchers discover the mechanism by which tumor cells become resistant to chemotherapy in colorectal cancer
A large number of cancer patients are treated with platinum-based therapy. However, many tumors are capable of developing resistance to treatment. In this study, the researchers examined tumor samples from patients and pre-clinical models of colorectal cancer to better understand the resistance to platinum-based therapy. They observed that platinum accumulates prominently in the healthy cells that surround the cancer cells, particularly in fibroblasts, the cells that contribute to tissue formation. Furthermore, this accumulation persists for more than two years after treatment has been completed. This discovery was made using techniques developed in geology and applied to biological samples.
Experts develop commercial formulation Campto for colorectal cancer
Announcing a new publication for Acta Materia Medica journal. The compound 7-ethyl-10-hydroxy-camptothecin (SN38) is a broad-spectrum antitumor agent whose applications are greatly limited by its poor solubility. Therefore, irinotecan, the hydrophilic derived prodrug of SN38, has been developed as the commercial formulation Campto® for colorectal cancer.
