Exosome Component 4 Promotes Epithelial Ovarian Cancer Cell Proliferation, Migration, and Invasion the Wnt Pathway.

Background: Of gynecologic malignancies, ovarian cancer is the leading cause of death, mainly due to the lack of sensitive tumor markers, which means it almost always presents at an advanced stage. Exosome Component 4 (EXOSC4) is involved in RNA degradation, but its role in epithelial ovarian cancer (EOC) is unclear.

Methods: The expression levels of EXOSC4 in EOC and normal ovarian tissue specimens were determined by immunohistochemical staining.

Natural variation at OsCERK1 regulates arbuscular mycorrhizal symbiosis in rice.

The symbiotic interaction between arbuscular mycorrhizal fungi (AMF) and land plants is essential for efficient nutrient acquisition and utilisation. Our understanding of key processes controlling the AMF colonisation in rice is still limited. Dongxiang wild rice (DY) exhibited a stronger colonisation with Rhizophagus irregularis than the rice cultivar Zhongzao 35 (ZZ35).

Genome Editing in Cowpea Using CRISPR-Cas9.

Cowpea () is widely cultivated across the world. Due to its symbiotic nitrogen fixation capability and many agronomically important traits, such as tolerance to low rainfall and low fertilization requirements, as well as its high nutrition and health benefits, cowpea is an important legume crop, especially in many semi-arid countries. However, research in is dramatically hampered by the lack of mutant resources and efficient tools for gene inactivation in vivo.

Arbuscular Mycorrhizal Fungal 14-3-3 Proteins Are Involved in Arbuscule Formation and Responses to Abiotic Stresses During AM Symbiosis.

Arbuscular mycorrhizal (AM) fungi are soil-borne fungi belonging to the ancient phylum Glomeromycota and are important symbionts of the arbuscular mycorrhiza, enhancing plant nutrient acquisition and resistance to various abiotic stresses. In contrast to their significant physiological implications, the molecular basis involved is poorly understood, largely due to their obligate biotrophism and complicated genetics. Here, we identify and characterize three genes termed , and that encode 14-3-3-like proteins in the AM fungi and , respectively.

Arbuscular Mycorrhizal Symbiosis Requires a Phosphate Transceptor in the Gigaspora margarita Fungal Symbiont.

The majority of terrestrial vascular plants are capable of forming mutualistic associations with obligate biotrophic arbuscular mycorrhizal (AM) fungi from the phylum Glomeromycota. This mutualistic symbiosis provides carbohydrates to the fungus, and reciprocally improves plant phosphate uptake. AM fungal transporters can acquire phosphate from the soil through the hyphal networks.

Streptomyces alfalfae sp. nov. and comparisons with its closest taxa Streptomyces silaceus, Streptomyces flavofungini and Streptomyces intermedius.

A novel streptomycete strain, designated XY25T, was isolated from the rhizosphere soil in an alfalfa field in Jingyang, Shanxi, China. The isolate showed optimal growth at 37 °C, and was capable of growing at pH 6-10 and in the presence of 0-6 % (w/v) NaCl. Mycelia of strain XY25T appeared spiral and developed into white spore chains with long-rod spores and a smooth surface.

HDAC9 promotes glioblastoma growth via TAZ-mediated EGFR pathway activation.

Histone deacetylase 9 (HDAC9), a member of class II HDACs, regulates a wide variety of normal and abnormal physiological functions. We found that HDAC9 is over-expressed in prognostically poor glioblastoma patients. Knockdown HDAC9 decreased proliferation in vitro and tumor formation in vivo.

Characterization and identification of the integrin family in silkworm, Bombyx mori.

As an important economic insect, Bombyx mori is also a useful model organism for lepidopteran insect. Integrins are evolutionarily conserved from sponges to humans, and play vital roles in many physiological and pathological processes. To explore their diverse functions of integrins in insect, eleven integrins including six α and five β subunits were cloned and characterized from silkworm.
