MicroRNA 421 induces the formation of high-invasive cell subsets of ovarian cancer from low-invasive cell subsets mediated by exosomes by activating the PI3K/AKT pathway.

Intratumoral heterogeneity (ITH) results in treatment failure in ovarian cancer (OC). Exosomes are related to the formation of a heterogeneous tumor microenvironment, and microRNAs play a crucial role in the progression of OC. Therefore, we aimed to explore the effect of exosomes and microRNA 421 (miR-421), which is mediated by exosomes, on ITH and the diagnosis of OC.

A nonclassically secreted effector of Magnaporthe oryzae targets host nuclei and plays important roles in fungal growth and plant infection.

Rice blast caused by Magnaporthe oryzae is one of the most destructive diseases and poses a growing threat to food security worldwide. Like many other filamentous pathogens, rice blast fungus releases multiple types of effector proteins to facilitate fungal infection and modulate host defence responses. However, most of the characterized effectors contain an N-terminal signal peptide.

Open Reading Frame 4 Is Not Essential in the Replication and Infection of Genotype 1 Hepatitis E Virus.

Genotype 1 hepatitis E virus (HEV-1), unlike other genotypes of HEV, has a unique small open reading frame known as ORF4 whose function is not yet known. ORF4 is located in an out-framed manner in the middle of ORF1, which encodes putative 90 to 158 amino acids depending on the strains. To explore the role of ORF4 in HEV-1 replication and infection, we cloned the complete genome of wild-type HEV-1 downstream of a T7 RNA polymerase promoter, and the following ORF4 mutant constructs were prepared: the first construct had TTG instead of the initiation codon ATG (A2836T), introducing an M→L mutation in ORF4 and a D→V mutation in ORF1.

Parametric Investigation into the Shear Strength of Adhesively Bonded Single-Lap Joints.

In this paper, the shear strength of adhesively bonded single-lap joints were experimentally and numerically investigated. Based on the validated simulation, the effects of lap length, adhesive layer thickness, adhesive layer shape, adhesive layer overflow length, and laminate lay-up on the shear strength of adhesively bonded single-lap joints were studied. The load-displacement curves and shear strength under different parameters were compared.

Routine blood test results and clinical information of patients with serous ovarian carcinoma were retrospectively collected.

Oral Microbiota-Driven Cell Migration in Carcinogenesis and Metastasis.

The oral cavity harbors approximately 1,000 microbial species, and both pathogenic and commensal strains are involved in the development of carcinogenesis by stimulating chronic inflammation, affecting cell proliferation, and inhibiting cell apoptosis. Moreover, some substances produced by oral bacteria can also act in a carcinogenic manner. The link between oral microbiota and chronic inflammation as well as cell proliferation has been well established.

Induces Increases in Branched-Chain Amino Acid Levels and Exacerbates Liver Injury Through .

, a keystone periodontal pathogen, has emerged as a risk factor for systemic chronic diseases, including non-alcoholic fatty liver disease (NAFLD). To clarify the mechanism by which this pathogen induces such diseases, we simultaneously analyzed the transcriptome of intracellular and infected host cells dual RNA sequencing. Pathway analysis was also performed to determine the differentially expressed genes in the infected cells.

Soy isoflavones alleviate periodontal destruction in ovariectomized rats.

Objective: The purpose of this study was to investigate whether soy isoflavone supplementation is effective in preventing periodontal destruction exacerbated by estrogen deficiency (ED) and its potential mechanism.

Background: The progression of periodontitis is affected by host factors, such as smoking, diabetes mellitus, and steroid use. Bone loss in periodontitis can be aggravated by ED.

Clinicopathological characteristics and treatment of patients with high-grade endometrial stromal sarcoma: A retrospective study of 40 cases.

Immunogenicity and Antigenicity of Rabbit Hepatitis E Virus-Like Particles Produced by Recombinant Baculoviruses.

Rabbit hepatitis E virus (HEV) is a novel HEV belonging to genotype 3 (HEV-3) in the species of the genus , family . Rabbit HEV was originally isolated from rabbits and found to cause zoonotic infection. Although rabbit HEV can be successfully grown in culture with several cell lines, including the human carcinoma cell line PLC/PRF/5, it is difficult to obtain the large amounts of viral antigen required for diagnosis and vaccine development.

Effects of CRM1-dependent nuclear export inhibition on viral structural protein nuclear accumulation during Autographa californica multiple nucleopolyhedrovirus infection.

Autographa californica multiple nucleopolyhedrovirus (AcMNPV) assembles its nucleocapsids and occlusion-derived virions (ODVs) in the nucleus, which requires AcMNPV regulation for viral structural proteins to accumulate in the nucleus during its replication in cells. It is generally accepted that the nuclear import receptor plays a predominant role in this process. CRM1 is a nuclear export receptor that forms an export complex with its cargo protein to exit the nucleus.

A Polyethylene Glycol-Based Method for Enrichment of Extracellular Vesicles from Culture Supernatant of Human Ovarian Cancer Cell Line A2780 and Body Fluids of High-Grade Serous Carcinoma Patients.

Objective: This study tried to evaluate whether 8% polyethylene glycol (PEG) 6000 precipitation combined with differential ultracentrifugation (PPDU) was an efficient and practical method for the enrichment and purification of extracellular vesicles (EVs) derived from the culture supernatant of human ovarian cancer cell line A2780 and from body fluids of patients with high-grade serous carcinoma (HGSC).

Methods: PPDU was used to enrich and purify the EVs derived from body fluids of patients with HSGC and cell culture supernatant of subclones of human ovarian cancer cell line A2780 with high/low invasive capacity (named as A-H/A-L, respectively). Transmission electron microscope (TEM) and nanoparticle tracking analysis (NTA) were used to identificate the EVs size and distribution.

Potential interaction between lysophosphatidic acid and tumor-associated macrophages in ovarian carcinoma.

Ovarian carcinoma is the deadliest type of gynecological cancer. The unique tumor microenvironment enables specific and efficient metastasis, weakens immunological monitoring, and mediates drug resistance. Tumor associated macrophages (TAMs) are a crucial part of the TME and are involved in various aspects of tumor behavior.

The Role of Lysophosphatidic Acid Receptors in Ovarian Cancer: A Minireview.

Lysophosphatidic acid (LPA) is a bioactive lipid component of ovarian cancer activating factor, which is present at a high concentration in the ascitic fluid and plasma of patients with ovarian cancer. A group of six lysophosphatidic acid receptors (LPARs), LPAR1 through LPAR6, which belong to the G protein-coupled receptor superfamily (GPCR), mediate cellular activities of LPA and activates a series of downstream molecules and cellular responses, including biological and pathological effects. LPARs are widely expressed in normal ovary, benign tumor, and ovarian cancer tissues and cancer cell lines with a broad range of levels.
