Lipoprotein particles are composed of various lipid classes including cholesterol and sphingolipids, and are low in serum of patients with liver cirrhosis. Hepatic decompensation is associated with a further decline of lipoproteins. Aim of the present work was to evaluate whether ceramide and sphingomyelin species are similarly changed in patients with liver cirrhosis and whether these variations are related to systemic cholesterol levels. In a cohort of 45 patients suffering from liver cirrhosis, cholesteryl ester species and subsequently total cholesterol were identified to be negatively associated with model of end stage liver disease (MELD) score...

Nuphar lutea L. SM., leaf and rhizome extracts (NUP), contain nupharidines as active components. Nupharidines belong to the sesquiterpene lactones class of a naturally occurring plant terpenoids. This family of compounds has gained considerable interest for treating infection, inflammation and cancer. NF-κB is a central, downstream regulator of inflammation, cell proliferation and apoptosis. In our previous work we demonstrated strong inhibition of NF-κB activity and induction of apoptosis by NUP. In addition, NUP exhibited anti-inflammatory properties and partial protection from LPS-induced septic shock by modulating ERK pathway and cytokine secretion in macrophages...

Long non-coding RNAs can regulate gene transcription, modulate protein function, and act as competing endogenous RNA. Yet, their roles in systemic lupus erythematosus remain to be elucidated. We determined the expression profiles of lncRNAs in T cells of SLE patients and healthy controls using microarrays. Up to 1935 lncRNAs and 1977 mRNAs were differentially expressed. QRT-PCR showed downregulated uc001ykl.1 and ENST00000448942 in SLE patients. Expression of uc001ykl.1 correlated with erythrocyte sedimentation rate (ESR) and C-reactive protein, whereas ENST00000448942 level correlated with ESR and anti-Sm antibodies...

Aims: Sirtuin 1 (SIRT1) inhibits nuclear factor kappa B (NF-κB) activity in response to the inflammatory cytokine tumour necrosis factor alpha (TNF-α). Smooth muscle (SM) 22α is a phosphorylation-regulated suppressor of IKK-IκBα-NF-κB signalling cascades in vascular smooth muscle cells (VSMCs). Sm22α knockout results in increased expression of pro-inflammatory genes in the aortas which are controlled by NF-κB. This study aimed to investigate the relationship between SM22α and SIRT1 in the control of vascular inflammation...
