The role of OIP5 in the carcinogenesis and progression of ovarian cancer.

Background: Opa interacting protein 5 (OIP5), which is a cancer/testis-specific gene, plays a cancer-promoting role in various types of human cancer. However, the role of OIP5 in the carcinogenesis and progression of ovarian cancer remains unknown.

Methods: We first analyzed the expression of OIP5 in ovarian cancer and various human tumors with the Sangerbox online analysis tool.

CG4968 positively regulates the immune deficiency pathway by targeting Imd protein in .

relies solely on innate immunity to defend against various microbial pathogens. Although it is well-known that the adaptor protein Imd undergoes K63-linked ubiquitination to activate the downstream signaling cascades, its involvement with K48-linked ubiquitination and what is responsible for controlling this modification remain largely unknown. In this study, we explored the immunological function of , which encodes a typical ovarian tumour-associated protease (OTU)-type deubiquitinase (Dub) in flies.

A Toll-dependent Bre1/Rad6-cact feedback loop in controlling host innate immune response.

The Toll signaling pathway was initially identified for its involvement in the control of early embryogenesis. It was later shown to be also part of a major innate immune pathway controlling the expression of anti-microbial peptides in many eukaryotes including humans; cactus, the essential negative regulator of this pathway in flies, was found to be induced in parallel to the Toll-dependent activation process during immune defenses. We were interested in the mechanisms of this dual effect and provide here evidence that upon pathogenic stimuli, dorsal, one of the transcription factors of the fly Toll pathway, can induce the expression of the E3 ligase Bre1.

E3 ligase Cul2 mediates Drosophila early germ cell differentiation through targeting Bam.

Drosophila ovary has been one of the most mature and excellent systems for studying the in vivo regulatory mechanisms of stem cell fate determination. It has been well-known that the bone morphogenetic protein (BMP) signaling released by the niche cells promotes the maintenance of germline stem cells (GSCs) through inhibiting the transcription of the bag-of-marbles (bam) gene, which encodes a key factor for GSC differentiation. However, whether Bam is regulated at the post-translational level remains largely unknown.

A conserved role of in maintaining metabolic homeostasis via regulating intestinal microbiota in .

Background: Previous studies have proven that () plays a pivotal role in promoting early germ cell differentiation in ovary. However, whether it functions in regulating the metabolic state of the host remains largely unknown.

Methods: We utilized GC-MS, qPCR, and some classical kits to examine various metabolic profiles and gut microbial composition in loss-of-function mutants and age-paired controls.

Corrigendum: A feedback regulatory loop involving dTrbd/dTak1 in controlling IMD signaling in .

[This corrects the article DOI: 10.3389/fimmu.2022.

A Feedback Regulatory Loop Involving dTrbd/dTak1 in Controlling IMD Signaling in .

Negative regulators of the inflammatory responses are essential for the maintenance of immune homeostasis and organismal fitness. In , the deubiquitinase (Dub) dTrbd selectively restricts the K63-linked ubiquitination modification of dTak1, a pivotal kinase of the IMD signaling pathway, to regulate the IMD innate immune response. However, which domain and how it functions to enable dTrbd's activity remain unexplored.

Salvianolic acid B inhibits the progression of liver fibrosis in rats via modulation of the Hedgehog signaling pathway.

Salvianolic acid B (Sal B) has previously reported anti-hepatic fibrosis effects, though it is not clear if it can inhibit hepatic fibrosis by regulating the hedgehog (Hh) signaling pathway. The aim of the present study was to explore the roles and mechanism of Sal B in preventing and treating liver fibrosis in rats. The study also aimed to determine the role of the Hh signaling pathway in this process.

Expression of nm23-H1, p53, and integrin β1 in endometriosis and their clinical significance.

To investigate the expression and clinical significance of nucleoside diphosphate kinase A (nm23-H1), p53, and integrin β1 in endometriosis, normal and ectopic endometrial tissues were collected and the levels of nm23-H1, p53, and integrin β1 proteins were detected by western blotting. We also measured the mRNA expression of nm23-H1, p53, and integrin β1 in endometrial epithelial cells by droplet digital PCR, based on endometrial tissues using laser capture microdissection. Moreover, primary stromal cells from normal and ectopic endometrial tissues were also cultured and treated with different concentrations of estrogen.

Molecular cloning, characterization, mRNA expression changes and nucleocytoplasmic shuttling during kidney embryonic development of SOX9 in Alligator sinensis.

SOX9 plays a crucial, extensive and conservative role in the process of somatic tissue development and adult regeneration through the positive self-regulation mediated by SOM across all vertebrates. In this study, we have cloned SOX9 from the kidney of hatchling Alligator sinensis. The full-length of SOX9 cDNA is 3878 bp with an open reading frame encoding 494 amino acids.
