Direct inhibition of MTX on NADPH (NADPH is a cofactor for enzyme GSH reductase to make reduced GSH) together with overproduction of ROS, will cause a reduction in GSH cellular availability.[ , , , ] Furthermore, the influence of MTX on Nrf2 expression might also reduce GSH tissue level.[] SOD is an essential endogenous antioxidant enzyme, induces the conversion of mitochondrial generated ROS, mainly superoxide (O2), into less toxic hydrogen peroxide (H2O2) or molecular oxygen (O2).[] On the other hand, MTX causes mitochondrial membrane damage, and more superoxide (O2) free radical production will lower SOD activity.[] Overproduction of ROS and loss of endogenous antioxidants will shift the oxidative balance toward oxidative stress
4.6 Antifungal drugs targeting antioxidant defense systems During infection, fungal pathogens are continuously exposed to oxidative stress generated by the host immune response (Yaakoub et al., 2022)
Randomized Trial
Strawberry Protein Shake A smooth, low-volume strawberry shake thats naturally sweet, easy to digest, and simple to adjust based on appetite
[27] Clinical significance [edit] Melanoma - Cancer affecting melanocytes Melanocytic tumors Melanocytic tumors of uncertain malignant potential Vitiligo - Decreased number of melanocytes due to autoimmune destruction causing decreased melanin Albinism - Normal number of melanocytes, but decreased melanin production due to decreased tyrosinase activity or defective tyrosine transport Melasma (Chloasma) - Patchy hyperpigmentation of the skin Normal number of melanocytes with increased melanin production causing hyperpigmentation
When administered, Melanotan II stimulates melanocortin receptorsparticularly MC1R which then trigger melanin production in the skin
