Bin Liu et al.
PloS one, 9(8), e106184-e106184 (2014-08-30)
Hepatic ischemia/reperfusion (I/R) injury is an unavoidable consequence of major liver surgery, especially in liver transplantation with bowel congestion, during which endotoxemia is often evident. The inflammatory response aggravated by endotoxin after I/R contributes to liver dysfunction and failure. The...

We recently showed that prenatal exposure to valproic acid (VPA) in mice causes autism-like behavioral abnormalities, including social interaction deficits, anxiety-like behavior and spatial learning disability, in male offspring. In the present study, we examined the effect of prenatal VPA...

Our knowledge of the molecular mechanisms underlying human embryonic stem cell (hESC) self-renewal and differentiation is incomplete. The level of octamer-binding transcription factor 4 (Oct4), a critical regulator of pluripotency, is precisely controlled in mouse embryonic stem cells. However, studies...

Proceedings of the National Academy of Sciences of the United States of America, 111(48), 17116-17121 (2014-11-19)
In the fasted state, increases in catecholamine signaling promote adipocyte function via the protein kinase A-mediated phosphorylation of cyclic AMP response element binding protein (CREB). CREB activity is further up-regulated in obesity, despite reductions in catecholamine signaling, where it contributes...

Endocrinology, 155(9), 3674-3683 (2014-06-17)
In many species, including mice, maternal responsiveness is experience-dependent and permanent, lasting for long periods (months to years). We have shown that after brief exposures to pups, virgin female mice continue to respond maternally toward pups for at least one...

PloS one, 9(11), e112698-e112698 (2014-11-14)
Alcohol insult triggers complex events in the liver, promoting fibrogenic/inflammatory signals and in more advanced cases, aberrant matrix deposition. It is well accepted that the regenerative capacity of the adult liver is impaired during alcohol injury. The liver progenitor/stem cells...

The enzymatic activity of histone deacetylases (HDACs) leads to a histone deacetylation-mediated condensed chromatic structure, resulting in transcriptional repression, which has been implicated in the modifications of neural circuits and behaviors. Repeated treatment with electroconvulsive seizure (ECS) induces changes in...
Muslima Chowdhury et al.
Proceedings of the National Academy of Sciences of the United States of America, 105(41), 15872-15877 (2008-10-07)
Ig class switch recombination (CSR) is initiated by activation-induced cytidine deaminase (AID) mediated deamination of the switch (S) regions; the resultant mismatch is processed to yield the DNA breaks required for recombination. Whereas many of the pathways involved in the...

Glial fibrillary acidic protein (GFAP) is the main intermediate filament in astrocytes and is regulated by epigenetic mechanisms during development. We demonstrate that histone acetylation also controls GFAP expression in mature astrocytes. Inhibition of histone deacetylases (HDACs) with trichostatin A...
