Changes in activities of caspase-8 and caspase-9 in human cervical malignancy.

Introduction: The apoptotic process of programmed cell death and its dysfunctions in a variety of human diseases, including cervical cancer, has become the focus of extensive scientific research. Caspases are considered key factors in the execution of apoptosis, although there are many aspects of their role to be elucidated. It has been found that disturbance of initiator caspase-8 and caspase-9 expression or function may contribute to cancer formation/progression, and inactivation of them could promote resistance to current treatment approaches.

Cytogenetic activity of diazepam in normal human lymphocyte cultures.

Introduction: Diazepam (DZ) belongs to benzodiazepines, a group of drugs used for sedation, for the relief of anxiety, and in the treatment of epilepsy. It has been found that DZ influences cytotoxic activity and diminishes antiviral and antitumor reactions in human natural killer cells in vitro. It has also been demonstrated that DZ causes a significant increase in the frequency of chromosomal aberrations in human lymphocytes in vitro.
