In lab and clinical research, its been observed to activate fibroblasts (the cells that produce collagen), increase glycosaminoglycan synthesis (which helps skin retain water), modulate matrix metalloproteinases (MMPs, the enzymes that break down old tissue), and act as a copper cofactor in antioxidant pathways

Patients who I recommend screen for MTHFR mutations: Pre-conception care: test both man and woman Mental dysfunction including but not limited to depression, anxiety, irritability, mood swings, schizophrenia, bipolar Infants and children of parents with MTHFR mutations Family members related to someone with MTHFR mutations Elevated folate (not processing to active 5-MTHF due to inability to methylate) Elevated homocysteine (due to low active 5-MTHF and methylcobalamin) Elevated s-adenosylhomocysteine (due to low active 5-MTHF and methylcobalamin) Elevated serum cobalamin (due to inability to methylate cyanocobalamin to methylcobalamin) Elevated methylmalonic acid (due to methylcobalamin deficiency) Patients with syndromes: IBS, Chemical sensitivity, Fibromyalgia, Down Syndrome, Chronic fatigue syndrome Neurological disorders: Multiple sclerosis, Autism, Alzheimers, Epilepsy, Parkinsons to name a few Cancer: family history of cancer or undergoing cancer treatment Cervical dysplasia Infertility Cardiovascular risk: family history of strokes, embolisms, heart attacks, clots, essential hypertension Birth defects: cleft palate, tetralogy of Fallot, spinal bifida, midline defects Drug sensitivities: methotrexate, anti-epileptics, nitrous oxide, anesthesia If you are interested in knowing more about your genes, the 23andme gene test will be the best $99 investment you've ever spent

To test the effect of Sp in paraquat-induced oxidative stress model, seven days old wild type flies, constitutively expressing mitochondrial (mt)-roGFP, were exposed to 10 mM paraquat for 24 h and then co-treated with 2.5 mM Sp for 24 h, prior to roGFP fluorescence estimation
A recent study reported that traumatic brain injury decreased the antioxidant capacity of the brain through the downregulation of Nrf2 and the resulting decrease of antioxidant proteins, such as GPx1
