miR-33a expression decreased in HPR and was negatively correlated with ABCA1 and Apo A-1 levels at 4th hour of the postprandial period in both groups.
Increased miR-122 and decreased miR-30c expression levels in HPR may play critical roles in elevated or prolonged postprandial lipemia. The miR122/30c ratio exhibited good association with MTTP, Apo B-48 and TG levels, and with CM particle size, and may be a reliable marker for evaluating postprandial lipemia. miR-33a may also play a key role in decreased HDL-C in postprandial lipemia.

In recent years, a new class of regulatory RNAs, long noncoding RNAs (lncRNAs), has been demonstrated to play an essential role in host gene expression. Growing literature indicate that lncRNAs function as positive or negative effectors on antibacterial immunity. On the one hand, the host regulates immune-related genes at epigenetic, transcriptional, and post-transcriptional levels by lncRNAs, thereby protecting itself from pathogen invasion. On the other hand, bacteria can manipulate the host signaling pathways by regulating the host lncRNAs to escape immune clearance. In addition, some bacteria even produce lncRNAs, which are involved in the pathogenic process of pathogens. Some dysregulated lncRNAs during bacterial infections can be used as a potential diagnostic marker for infection. Understanding of gene expression regulation through lncRNAs helps illustrate bacterial pathogenesis. Here, we summarize the functions of lncRNAs and current advances of lncRNAs in different bacterial infections and look forward to the future research orientation.
To investigate the role and prognostic value of mH2A1 in the progression of hepatocellular carcinoma (HCC).
Basing on the Cancer Genome Atlas-Liver Hepatocellular Carcinoma (TCGA-LIHC) and GEO datasets, the gene expression of mH2A1 and relative clinical characteristics were analyzed to assess the prognostic significant of mH2A1 in HCC. The protein expression of mH2A1 was measured by immunohistochemistry. Stable cell lines and nude mice model were used to investigate the role of mH2A1 in the progression of HCC.
In this study, using TCGA-LIHC data and HCC tissue microarray, we found that expression of mH2A1 was higher in tumor tissues than in adjacent normal tissues. These results were validated using the GEO database. Patients with high levels of mH2A1 were predicted to have larger tumor size and more advanced tumor stage and grade. Multivariate analysis revealed that increased mH2A1 expression was an independent prognostic risk factor of shorter overall survival (OS). Experimental results showed that elevated mH2A1 expression promoted the progression of HCC while reduced mH2A1 expression lead to opposite effects in vitro and in vivo. mH2A1 promoted the progression of HCC by regulating cell cycle via AKT. Dysregulated expression of mH2A1 was associated with its DNA methylation status. Two CpG sites (cg01466741 and cg02614129) were negatively correlated with mH2A1 expression. Notably, high methylation of both CpG sites was associated with better OS.
Based on the above results, we concluded that upregulated mH2A1 in HCC promoted tumor progression and could serve as an unfavorable prognostic indicator.

Fingolimod (FTY720), a sphingosine analogue approved for the treatment of multiple sclerosis, has a significant neuroprotective effect on the central nervous system. The aim of this study was to determine the potential therapeutic effect of FTY720 on the behavior and cognitive function of rats exposed daily to chronic unpredictable mild stress (CUMS), and elucidate the underlying mechanisms. The 42-day CUMS modeling induced depression-like behavior as indicated by the scores of sugar water preference, forced swimming, open field and Morris water maze tests. Mechanistically, CUMS caused significant damage to the hippocampal neurons, increased inflammation and oxidative stress, activated the NF-κB/NLRP3 axis, and skewed microglial polarization to the M1 phenotype. FTY720 not only alleviated neuronal damage and oxidative stress, but also improved the depression-like behavior and cognitive function of the rats. It also inhibited NF-κB activation and blocked NLRP3 inflammasome assembly by down-regulating NLRP3, ACS and caspase-1. Furthermore, FTY720 inhibited the microglial M1 polarization markers iNOS and CD16, and promoted the M2 markers Arg-1 and CD206. This in turn reduced the levels of TNF-α, IL-6 and IL-1β, and increased that of IL-10 in the hippocampus. In conclusion, FTY720 protects hippocampal neurons from stress-induced damage and alleviates depressive symptoms by inhibiting neuroinflammation.

However, the understanding of immune mechanisms during Ehrlich carcinogenesis is still limited. In this review, we seek to describe the immune response during Ehrlich's tumor growth, and natural response without the influence of pharmacological administration, immunotherapies or concomitant challenges. The study followed the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA). A systematic review was carried out that included experimental trials with mice challenged with Ehrlich's tumor. The research was carried out in three databases including MEDLINE/PubMed, Scopus, Latin American and Caribbean Literature in Health Sciences (LILACS). The searches resulted in 913 papers being found, of which 55 articles were considered eligible, and of these 55, 29 were selected for analysis.
