Members of the Bcl-2 protein family are regulated through pathways influenced by estradiol, such that tumour cell expression of oestrogen receptors directly controls Bcl-2 levels (55, 56) Bcl-2-associated athanogene-1 (Bag-1), a Bcl-2-associated athanogene, functions as an anti-apoptotic protein by interacting with Bcl-2
As a result, pyridoxine deficiency can lead to relevant neuropsychiatric manifestations, such as reduced neurotransmitter synthesis, depression, epilepsy, premature aging of neurons, paresthesias, cerebrovascular diseases, cognitive impairment and carpal tunnel syndrome (58) In contrast, pyridoxine may have therapeutic potential for treating depression or aggressive behavior, since pyridoxine plays a crucial role in the tryptophan-serotonin pathway (61, 62)
