In the present study, miR-23b inhibitor and mimics sequences

were transfected into human vascular endothelial cells to inhibit and upregulate the expression of miR-23b, respectively. In addition, respective negative control (NC) sequences were transfected. The expression of miR-23b was found to be downregulated in the cells transfected with the mimics NC or inhibitor NC sequences following stimulation with lipopolysaccharide (LPS; P smaller than 0.01); however, higher expression levels were maintained in the cells transfected with the mimics sequence and very low levels were observed in the cells transfected with the inhibitor sequence. In addition, the expression levels of nuclear factor (NF)-B, tumor necrosis factor TH-302 (TNF)-, interleukin (IL)-6, intercellular adhesion molecule (ICAM)-1, E-selectin and vascular cell adhesion molecule (VCAM)-1 were shown to increase following induction by LPS in the cells transfected with inhibitor/mimics NC sequences (P smaller than 0.05). However, the expression levels of these inflammatory factors decreased in the cells transfected with the mimics sequence, and increased to a greater degree in the cells transfected with the inhibitor sequence, as GSK3235025 compared with the inhibitor NC sequences (P smaller than 0.05). Therefore, miR-23b may play a significant role in the pathogenesis

and progression of sepsis by inhibiting the expression of inflammatory factors, including NF-B, TNF-, IL-6, ICAM-1, E-selectin and VCAM-1.”
“In patients with cirrhosis, adrenal insufficiency (AI) is reported during sepsis and septic shock and is associated with increased mortality. Consequently, the term hepato-adrenal

syndrome was proposed. Some studies Androgen Receptor Antagonists high throughput screening have shown that AI is frequent in stable cirrhosis as well as in cirrhosis associated with decompensation other than sepsis, such as bleeding and ascites. Moreover, other studies showed a high prevalence in liver transplant recipients immediately after, or some time after, liver transplantation. The effect of corticosteroid therapy in critically ill patients with liver disease has been evaluated in some studies, but the results remain controversial. The 250-mu g adreno-cortico-tropic-hormone stimulation test to diagnose AI in critically ill adult patients is recommended by an international task force. However, in liver disease, there is no consensus on the appropriate tests and normal values to assess adrenal function; thus, standardization of normal ranges and methodology is needed. Serum total cortisol assays overestimate AI in patients with cirrhosis, so that direct free cortisol measurement or its surrogates may be useful measurements to define AI, but further studies are needed to clarify this. In addition, the mechanisms by which liver disease leads to adrenal dysfunction are not sufficiently documented.
