ABCs of RhoGTPases indicating potential role as oncotargets

Deubiquitinating enzymes as oncotargets

Carcinogenesis is a complex process tightly regulated at multiple levels by post-translational modifications. Epigenetics plays a major role in cancer development, all stable changes to the gene expression process that are not a result of a direct change in the DNA code are described as epigenetics. Epigenetic processes are regulated by post-translational modifications including ubiquitination ...

Eph receptors as oncotargets

Glutathione peroxidases as oncotargets

Oxidative stress is a disturbance in the equilibrium among free radicals, reactive oxygen species, and endogenous antioxidant defense mechanisms. Oxidative stress is a result of imbalance between the production of reactive oxygen and the biological system's ability to detoxify the reactive intermediates or to repair the resulting damage. Mounting evidence has implicated oxidative stress in vari...

RhoGTPases as Key Players in Mammalian Cell Adaptation to Microgravity

A growing number of studies are revealing that cells reorganize their cytoskeleton when exposed to conditions of microgravity. Most, if not all, of the structural changes observed on flown cells can be explained by modulation of RhoGTPases, which are mechanosensitive switches responsible for cytoskeletal dynamics control. This review identifies general principles defining cell sensitivity to gr...

Voltage-dependent K+ channels as oncotargets in malignant gliomas

Because both imipramine and citalopram have been commonly used to treat depression, which commonly occurs in glioma patients, it would be interesting to conduct large epidemiological studies to investigate the actual benefit that these two drugs would provide for malignant glioma patients when delivered during their glioma treatment. Such large-scale epidemiological studies have recently reveal...
