Schistosomes are flatworm parasites that undergo a complex life cycle involving two hosts. The regulation of the parasite's developmental processes relies on both coding RNAs and non-coding RNAs. However, the roles of non-coding RNAs, including long non-coding RNAs (lncRNAs) in schistosomes remain largely unexplored.

Schistosomiasis is a zoonotic parasitic disease caused by schistosome infection that severely threatens human health. Therapy relies mainly on single drug treatment with praziquantel. Therefore, there is an urgent need to develop alternative medicines.

Article Synopsis
  • Schistosomiasis is a serious parasitic disease that negatively affects health in tropical and subtropical areas, with Schistosoma japonicum having different ferritin isoforms (SjFer0, SjFer1, SjFer2) whose roles in parasite growth are not well understood.
  • Researchers constructed a phylogenetic tree to examine the evolutionary relationships of these ferritins, used RNA interference to study the effect of SjFer0 on parasite development, and employed immunofluorescence and RNA-sequencing for further analysis.
  • The findings showed that SjFer0 is distinct from the other isoforms and plays a crucial role in schistosomula growth, while SjFer1 and SjFer2 do not significantly influence growth or egg production

Schistosoma japonicum is prevalent in Asia with a wide mammalian host range, which leads to highly harmful zoonotic parasitic diseases. Most previous transcriptomic studies have been performed on this parasite, but mainly focus on stages inside the mammalian host. Moreover, few larval transcriptomic data are available in public databases.

T cell immunoglobulin and mucin domain 3 (TIM-3) was originally found to be expressed on the surface of Th1 cells, acting as a negative regulator and binding to the ligand galectin-9 to mediate Th1 cell the apoptosis. Recent studies have shown that TIM-3 is also expressed on other immune cells, such as macrophages, dendritic cells, and monocytes. In addition, TIM-3 ligands also include Psdter, High Mobility Group Box 1 (HMGB1) and Carcinoembryonic antigen associated cell adhesion molecules (Ceacam-1), which have different effects upon biding to different ligands on immune cells.

() is one of the etiological agents of schistosomiasis, a widespread zoonotic parasitic disease. However, the mechanism of the balanced co-existence between the host immune system and as well as their complex interaction remains unclear. In this study, rRNA gene sequencing, combined with metagenomic sequencing approach as well as ultraperformance liquid chromatography-mass spectrometry metabolic profiling, was applied to demonstrate changes in the gut microbiome community structure during schistosomiasis progression, the functional interactions between the gut bacteria and infection in BALB/c mice, and the dynamic metabolite changes of the host.

Schistosomiasis is a zoonotic and debilitating parasitic disease caused by . Praziquantel remains the choice for treating schistosomiasis, but its efficacy could be hampered by emergence of resistance. In this study, using large-scale drug screening, we selected out myricetin, a natural flavonol compound, having a good anti-schistosome effect.

Article Synopsis
  • Triatoma rubrofasciata, an invasive insect species, has been increasingly found in southern China, but its origin in the region is still unclear.
  • Researchers collected triatomine specimens from Guangdong and Fujian provinces and conducted morphological and genetic analyses, identifying them as T. rubrofasciata.
  • The findings suggest that the Chinese populations of T. rubrofasciata share genetic links with strains from Vietnam and Brazil, marking the first record of this species in those specific regions of China.

ANO1 is a calcium-activated chloride channel protein that has been used to diagnose GISTs after tissue biopsy. Recently, ANO1 mRNA amplification in the blood has received considerable attention as a useful method for the diagnosis of GISTs. The aim of this study was to evaluate the diagnostic ability of ANO1 mRNA in distinguishing GIST patients from healthy subjects.

Accumulating evidence has suggested that microRNAs play important roles in the development of hepatocellular carcinoma (HCC) and are involved in drug resistance. miR-21-5p was overexpressed in a variety of cancers and promoted the tumorigenesis; however, the function of miR-21-5p in HCC still remains unknown. In this study, our results showed that miR-21-5p was highly expressed in HCC tissues and cell lines.

Objective: MicroRNAs (miRNAs) have emerged as promising regulators of diabetes mellitus (DM)-induced angiogenic dysfunction in endothelial cells (ECs), but information vis-à-vis the functional roles of distinct miRNAs remain surprisingly scarce. The current study was designed to elucidate the expression and function of miR-140-3p in diabetic ECs.

Methods: miR-140-3p expression was evaluated in DM mouse model and in human ECs using RT-qPCR, Northern blot and RNA fluorescent in situ hybridization.

Understanding the function and molecular relevance of distinct miRNAs in endothelial cells (ECs) paves avenues for possible therapeutic intervention by targeting epigenetic mechanisms in vascular endothelial dysfunction, one of the major complications of type 2 diabetes mellitus (T2DM). MiR-342-3p, an obesity-associated miRNA, has recently been shown to be significantly upregulated in human angiosarcoma compared to benign hemangioma, indicating its potential involvement as a proangiogenic factor. Herein, we show that endothelial miR-342-3p expression was significantly compromised in T2DM organisms and this inhibition powerfully blocked vasculogenesis in vivo by repressing endothelial proliferation and migration.

Objective: To explore the human papilloma virus (HPV) infection and genotypes distribution in female patients with cervical intraepithelial neoplasia so as to provide rationales for preventing and treating HPV and developing HPV vaccine.

Methods: Polymerase chain reaction (PCR) amplification, flow-through hybridization and gene chip were used to identify 23 HPV genotypes in cervical cells collected from 823 female patients with cervical intraepithelial neoplasia at Third Municipal People's Hospital and Central Municipal Hospital during January 2011 and December 2013.

Results: Among them, HPV infections were detected in 47.
