Estrogen Reduces Caspase-3 Expression in the Inner Ear of Guinea Pigs Exposed to Simulated Microgravity and Inboard Noises of Spaceship
نویسندگان
چکیده
RESULTS: On the first day of exposure to the stimulus, the auditory brainstem response thresholds were lower in the treatment group than in the control and prevention groups. After 3-day recovery, the prevention group showed a greater auditory brainstem response threshold shift than the other two groups. The expression of caspase-3 in hair cells and stria vascularis cells was weaker in the treatment group on the first day of the exposure. However, after 3-day recovery, caspase-3 expression was weaker in the prevention group.

Simulated Microgravity Condition Alters the Gene Expression of some ECM and Adhesive Molecules in Adipose-Derived Stem Cells
Adipose-derived stem cells (ADSCs) are widely used for tissue engineering and regenerative medicine. The beneficial effects of ADSCs on wound healing have already been reported. Remodeling of extracellular matrix (ECM) is the most important physiological event during the wound healing. ECM is sensitive to mechanical stresses and the expression of its components can be therefore influenced. The ...

متن کاملCD44 expression changes and increased apoptosis in MCF-7 cell line of breast cancer in simulated microgravity condition
Introduction: Studies have shown that simulated microgravity (SMG) affects tumor cell proliferation and metastasis. However, the underlying mechanism and its molecular basis are still not well known. In recent years, due to the role of CD44 in breast cancer and its high expression in invasive basal tumors, it has been the subject of extensive research. There is a conflicting data on the role of...
متن کاملExpression pattern of neurotrophins and their receptors during neuronal differentiation of adipose-derived stem cells in simulated microgravity condition
Objective(s): Studies have confirmed that microgravity, as a mechanical factor, influences both differentiation and function of mesenchymal stem cells. Here we investigated the effects of simulated microgravity on neural differentiation of human adipose-derived stem cells (ADSCs). Materials and Methods:We have used a fast rotating clinostat (clinorotation) to simulate microgravity condition. R...
