Yin Yang 1 and guanine quadruplexes protect dopaminergic neurons from cellular stress via transmissive dormancy [BG4 CUT&RUN]

Project description:Neurons deploy diverse adaptive strategies to ensure survival and neurotransmission amid cellular stress. When these adaptive pathways are overwhelmed, functional impairment or neurodegeneration follows. Here, we report a scenario where stressed neurons actively induce a state of transmissive dormancy as a protective measure. Examination of dopaminergic neurons surviving severe cellular challenges revealed decreased spontaneous activity accompanied by dynamic control of dopamine metabolism through the transcriptional regulator Yin Yang 1 (YY1). Under these conditions, YY1 increases expression of the vesicular monoamine transporter 2, promoting sequestration of dopamine into synaptic vesicles. Following oxidative stress and subsequent DNA damage, YY1 inhibits dopamine synthesis through stabilization of a guanine quadruplex in intron 10 of tyrosine hydroxylase. This cytoprotective response has the potential to drive circuit inactivation and safeguard neurons by minimizing the toxic accumulation of cytosolic dopamine and inducing a state of neuronal dormancy. In essence, neurons appear to actively prioritize viability over functionality.

Yin Yang 1 and guanine quadruplexes protect dopaminergic neurons from cellular stress via transmissive dormancy [YY1 CUT&RUN]

Project description:Neurons deploy diverse adaptive strategies to ensure survival and neurotransmission amid cellular stress. Yet, when these adaptive pathways are overwhelmed, functional impairment or neurodegeneration follow. Herein we report a scenario where stressed neurons actively adopt a state of transmissive dormancy, despite rapid activation of stress response pathways, as a terminal protective measure. Examination of dopaminergic neurons surviving severe cellular stress, revealed decreased spontaneous activity accompanied by dynamic control of dopamine metabolism through the Yin Yang 1 (YY1) transcriptional regulator. Under conditions of ionic imbalance or oxidative stress, YY1 promotes expression of the SLC18A2 transporter with the capacity to enhance sequestration of dopamine into transport vesicles. Subsequent DNA damage represses the rate-limiting enzyme in dopamine synthesis, tyrosine hydroxylase (TH), through YY1 mediated stabilization of an intronic guanine quadruplex. This cascade has the potential to drive circuit inactivation and safeguard neurons by minimizing the toxic accumulation of cytosolic dopamine and reducing the energetic expenditure associated with cellular depolarization. In essence, neurons appear to actively prioritize viability over functionality.

Genes expression profiles of postmenopausal osteoporosis with kidney Yin deficiency

Project description:Investigate genes expression profiles of postmenopausal osteoporosis with kidney Yin deficiency in peripheral blood By TCM syndrome, 10 patients with postmenopausal osteoporosis were divided into three groups: kidney Yin deficiency (n=4), kidney Yang deficiency (n=3), non-kidney deficiency (n=3), another 3 healthy postmenopausal women also were selected as control group. Whole human genome oligo microarray were applied to explore gene expression difference of the groups. Kidney Yin deficiency group was compared with other three groups respectively.
