objective: micrornas (mirna) are a class of non-coding rnas which play key roles in post-transcriptional gene regulation. previous studies indicate that mirnas are dysregulated in patients with multiple sclerosis (ms). th17 and regulatory t (treg) cells are two subsets of cd4+ t-cells which have critical functions in the onset and progression of ms. the current study seeks to distinguish fluctu...

Homeostatic regulation is essential for the maintenance of synaptic strength within the physiological range. The current study is the first to demonstrate that both induction and reversal of homeostatic upregulation of synaptic vesicle release can occur within seconds of blocking or unblocking acetylcholine receptors at the mouse neuromuscular junction. Our data suggest that the homeostatic upr...

UNLABELLED Suppressors of cytokine signaling (SOCS) proteins are intracellular proteins that inhibit cytokine signaling in a variety of cell types. A number of viral infections have been associated with SOCS upregulation; however, not much is known about the mechanisms regulating SOCS expression during viral infection. In this study, we used two pathologically distinct intracerebral (i.c.) infe...

Ischemic and oxidative damage to the hypothalamus may be associated with decreased heat tolerance as well as heatstroke formation. The present study explores the hypothalamic proteome mechanisms associated with heatstroke-mediated hypothalamic ischemia, and oxidative damage. Heatstroke rats had hypotension, hypothalamic ischemia, and lethality. In addition, they had hyperthermia and hypothalami...

miR-196b plays a significant role in the regulation of tumor pathogenesis and progression by promoting tumor cell proliferation, invasion and metastasis. In order to explore the effects of miR-196b on the proliferation and invasion ability of gastric cancer cells and the involved mechanisms, in the present study the lentivirus expression vector miR-196b was constructed and transfected into the ...

Differentiation of presynaptic nerve terminals involves changes in gene expression; these may be regulated by synaptic transmission and/or by contact with the target muscle. To gain insight into the control of presynaptic differentiation, we examined the regulation by target and synaptic activity of synaptic vesicle protein (SVP) genes in the chick ciliary ganglion (CG). In the CG, two SVP gene...

OBJECTIVE Hypothalamic leptin resistance is found in most common forms of obesity, such as diet-induced obesity, and is associated with increased expression of suppressor of cytokine signaling 3 (Socs3) in the hypothalamus of diet-induced obese animals. This study aims to determine the functional consequence of Socs3 upregulation on leptin signaling and obesity, and to investigate whether Socs3...
