IL6-STAT3-C/EBPβ-IL6 positive feedback loop in tumor-associated macrophages promotes the EMT and metastasis of lung adenocarcinoma.

Background: Lung cancer is one of the most common tumors in the world, and metastasis is one of the major causes of tumor-related death in lung cancer patients. Tumor-associated macrophages (TAMs) are a major component of the tumor microenvironment (TME) and are frequently associated with tumor metastasis in human cancers. However, the regulatory mechanisms of TAMs in lung cancer metastasis remain unclear.

Dynamic effects of miR-20a-5p on hippocampal ripple energy after status epilepticus in rats.

To determine the dynamic effects of miR-20a-5p on hippocampal ripple energy in rats after status epilepticus (SE). A lithium pilocarpine (LiCl-PILO)-induced rat model of status epilepticus (SE) was established, and the rats were divided into the normal control (Control, CTL), epileptic control (PILO), valproic acid (VPA + PILO), miR-20a-5p overexpression lentivirus vector (miR + PILO), sponges blocking lentivirus vector (Sponges + PILO), and scramble sequence negative control (Scramble + PILO) groups (n = 6). Electroencephalograms (EEGs) were used to analyze changes in hippocampal ripple energy before and after SE.

FSCN1 induced PTPRF-dependent tumor microenvironment inflammatory reprogramming promotes lung adenocarcinoma progression via regulating macrophagic glycolysis.

Purpose: Macrophages (MΦs) play a dual role in the promotion and suppression of lung adenocarcinoma (LUAD), the function of which is influenced by the metabolic status. The role of protein tyrosine phosphatase receptor type F (PTPRF) in cancer has not been elucidated, and its role in MΦs remains to be seen.

Methods: The Seahorse XFe 96 Cell Flow Analyzer detected glucose metabolism in tumor cells and macrophages.

Anticonvulsant Effect of Carbenoxolone on Chronic Epileptic Rats and Its Mechanism Related to Connexin and High-Frequency Oscillations.

Objective: This study was designed to investigate the influence and mechanism of gap junction carbenoxolone (CBX) on dynamic changes in the spectral power of ripples and fast ripples (FRs) in the hippocampus of chronic epileptic rats.

Methods: The lithium-pilocarpine (PILO) status epilepticus (SE) model (PILO group) and the CBX pretreatment model (CBX + PILO group) were established to analyze dynamic changes in the spectral power of ripples and FRs, and the dynamic expression of connexin (CX)26, CX32, CX36, and CX43 in the hippocampus of chronic epileptic rats.

Results: Within 28 days after SE, the number of spontaneous recurrent seizures (SRSs) in the PILO group was significantly higher than that in the CBX + PILO group.

Pseudaestuariivita rosea sp. nov., isolated from Acmaea sp., a marine mollusk.

A Gram-stain-negative, pink-pigmented, aerobic, non-motile and rod-shaped bacterium, designated as strain H15, was isolated from Acmaea sp., collected from Weihai, Shandong Province, China. The novel isolate was able to grow at 4-37 °C (optimum 33 °C), pH 5.

Differences in genetics and microenvironment of lung adenocarcinoma patients with or without TP53 mutation.

Background: Differences in genetics and microenvironment of LUAD patients with or without TP53 mutation were analyzed to illustrate the role of TP53 mutation within the carcinogenesis of LUAD, which will provide new concepts for the treatment of LUAD.

Methods: In this study, we used genetics and clinical info from the TCGA database, including somatic mutations data, RNA-seq, miRNA-seq, and clinical data. More than one bioinformatics tools were used to analyze the unique genomic pattern of TP53-related LUAD.

Effect of gap junction blockers on hippocampal ripple energy expression in rats with status epilepticus.

Objectives: To study the effect of gap junction blockers, quinine (QUIN) and carbenoxolone (CBX), on hippocampal ripple energy expression in rats with status epilepticus (SE).

Methods: A total of 24 rats were randomly divided into four groups: model, QUIN, valproic acid (VPA), and CBX (=6 each). A rat model of SE induced by lithium-pilocarpine (PILO) was prepared.

[Directional breeding of high oil content peanut variety Yuhua 9 by in vitro mutagenesis and screening].

Leaf water potential of peanut subjected to drought stress is positively related to the oil content of peanut kernels. The aim of this study was to directly screen the high oil mutants of peanut and create the new peanut varieties using hydroxyproline as water potential regulator. In vitro mutagenesis was carried out with the embryonic leaflets of peanut variety Huayu 20 as explants and pingyangmycin as a mutagen added into the somatic embryo formation medium.

Constitutive expression of GmF6'H1 from soybean improves salt tolerance in transgenic Arabidopsis.

Coumarin plays a pivotal role in plant response to biotic stress, as well as in the mediation of nutrient acquisition. However, its functions in response to abiotic stresses are largely unknown. In this work, a homologous gene, GmF6'H1, of AtF6'H1, which encodes the enzyme catalyzing the final rate-limiting step in the biosynthesis pathway of coumarin, was isolated from soybean.

A novel NOTCH3 mutation identified in patients with oral cancer by whole exome sequencing.

Oral cancer is a serious disease caused by environmental factors and/or susceptible genes. In the present study, in order to identify useful genetic biomarkers for cancer prediction and prevention, and for personalized treatment, we detected somatic mutations in 5 pairs of oral cancer tissues and blood samples using whole exome sequencing (WES). Finally, we confirmed a novel nonsense single-nucleotide polymorphism (SNP; chr19:15288426A>C) in the NOTCH3 gene with sanger sequencing, which resulted in a N1438T mutation in the protein sequence.

Regulatory function of Arabidopsis lipid transfer protein 1 (LTP1) in ethylene response and signaling.

Ethylene as a gaseous plant hormone is directly involved in various processes during plant growth and development. Much is known regarding the ethylene receptors and regulatory factors in the ethylene signal transduction pathway. In Arabidopsis thaliana, REVERSION-TO-ETHYLENE SENSITIVITY1 (RTE1) can interact with and positively regulates the ethylene receptor ETHYLENE RESPONSE1 (ETR1).

Responses to copper by the moss Plagiomnium cuspidatum: hydrogen peroxide accumulation and the antioxidant defense system.

Using both histochemical and cytochemical methods, we investigated the effects of copper (Cu) on the production of hydrogen peroxide (H2O2) and superoxide anion (O2(.-)) in the leaves of the moss Plagiomnium cuspidatum. Cu treatment significantly increased the contents of total thiobarbituric acid-reactive substances and H2O2, as well as the activity of guaiacol peroxidase and superoxide dismutase (SOD).
