A guide for the analysis of long-term population growth in cancer.

Although cancer is a chronic disease, most of the in vitro experiments to assess the effectiveness of intervention are performed in hours or a few days. Moreover, none of the available methodologies to measure cell proliferation are adapted to provide information about the growth kinetic during and after treatment. Thus, the objective of this work is to provide a guide to assess long-term changes in cell population size to be used mainly in cancer research.

Sensitization of glioma cells by X-linked inhibitor of apoptosis protein knockdown.

Objective: Glioblastomas are a kind of cancer with high resistance to treatments, requiring more efficient alternatives of treatment. X-linked inhibitor of apoptosis (XIAP) is highly expressed in gliomas and, due to its inhibition of caspases, can participate in resistance to therapy. Here we test the sensitization of glioma cells with XIAP gene knockdown (KD) to drugs used in chemotherapy.

Ecto-5'-nucleotidase/CD73 knockdown increases cell migration and mRNA level of collagen I in a hepatic stellate cell line.

Enhancement of drug delivery to bone: characterization of human tissue-nonspecific alkaline phosphatase tagged with an acidic oligopeptide.

Hypophosphatasia is caused by deficiency of activity of the tissue-nonspecific alkaline phosphatase (TNSALP), resulting in a defect of bone mineralization. Enzyme replacement therapy (ERT) with partially purified plasma enzyme was attempted but with little clinical improvement. Attaining clinical effectiveness with ERT for hypophosphatasia may require delivering functional TNSALP enzyme to bone.
