BNIP3 in hypoxia-induced mitophagy: Novel insights and promising target for non-alcoholic fatty liver disease.

BNIP3 localizes to the outer mitochondrial membrane, has been demonstrated to be extensively involved in abnormalities to mitochondrial metabolic function and dynamicsand in non-alcoholic fatty liver disease (NAFLD). However, its role in NAFLD under hypoxia remains unclear. This study aimed to investigate the expression and the role of BNIP3 in NAFLD under hypoxia, and explore its involvement in regulating NAFLD mitophagy, fatty acid β-oxidation both in vivo and in vitro.

Expression of protein phosphatase 4 in different tissues under hypoxia.

Relevant research data shows that there is a certain degree of energy metabolism imbalance in highland residents. Protein phosphatase 4 (PP4) has been found as a new factor in the regulation of sugar and lipid metabolism. Here, we investigate the differential expression of PP4 at a simulated altitude of 4,500 m in the heart, lung, and brain tissues of rats.

protoscoleces enhance glycolysis to promote M2 Macrophages through PI3K/Akt/mTOR Signaling Pathway.

Alveolar Echinococcosis (AE) is a zoonotic parasitic disease caused by , but its pathogenesis remains unclear. The primary objective of this study is to explore whether protoscoleces (PSCs) regulate macrophage polarization and glucose metabolism by PI3K/Akt/mTOR signaling pathway. We found that large numbers of CD68 macrophages gathered in close liver issue from the lesion in AE patients.

The effects of hypoxia on mitochondrial function and metabolism in gastric cancer cells.

Background: A number of studies have found that metabolic disorders are the characteristic manifestations of tumor cells. However, the effects of hypoxic environment on mitochondrial function and glucose metabolism of tumor cells were still unclear. The study wanted to explore the regulatory mechanism of hypoxic environment on mitochondrial function and metabolism in gastric cancer cells.

Lactate Modulates Cellular Metabolism Through Histone Lactylation-Mediated Gene Expression in Non-Small Cell Lung Cancer.

Lactate has been observed to fuel TCA cycle and is associated with cancer progression in human lung cancer, the leading cause of cancer deaths worldwide, but the effect of lactate on lung cancer metabolism is rarely reported. In this study, disordered metabolism in non-small cell lung cancer was demonstrated by increased G6PD and SDHA protein levels immunofluorescence, and up-regulated lactate dehydrogenase was found to be associated with poor prognosis. Then flow cytometry and Seahorse XFe analyzer were utilized to detect the effect of lactate on glycolysis and mitochondrial function in non-small cell lung cancer cells.

High-concentration homocysteine inhibits mitochondrial respiration function and production of reactive oxygen species in neuron cells.

Objective: Homocysteine plays critical roles in cellular redox homeostasis, and hyperhomocysteinemia has been associated with multiple diseases, including neurological disorders involving reactive oxygen species-inducing and pro-inflammatory effects of homocysteine that are related to mitochondria. This study investigated the role of homocysteine in regulating mitochondria of neuron cell lines.

Methods: Neuron cells were pre-treated with homocysteine, and then flow cytometry was used to detect reactive oxygen species production and mitochondrial membrane potential, while Seahorse XFp Mito stress assay was used to comprehensively analyze mitochondrial function.

The association between homocysteine and ischemic stroke subtypes in Chinese: A meta-analysis.

Background: The findings on the association between elevated plasma homocysteine levels and the risk of the trial of org 10172 in acute stroke treatment (TOAST) of ischemic stroke have been inconsistent in Chinese. So far, there is no meta-analysis about the association between Hcy and the TOAST subtypes of ischemic stroke in Chinese. This study; therefore, aimed to evaluate whether elevated homocysteine levels are associated with the TOAST subtypes of ischemic stroke using a meta-analysis.

Identification of the tropomyosin (HL-Tm) in Haemaphysalis longicornis.

Haemaphysalis longicornis tropomyosin (HL-Tm) was amplified by RT-PCR. The cDNA contained a 825 bp open reading frame coding for 274 amino acids with a predicted theoretical isoelectric point (pI) of 4.55 and molecular weight of 31.

RPS8--a new informative DNA marker for phylogeny of Babesia and Theileria parasites in China.

Piroplasmosis is a serious debilitating and sometimes fatal disease. Phylogenetic relationships within piroplasmida are complex and remain unclear. We compared the intron-exon structure and DNA sequences of the RPS8 gene from Babesia and Theileria spp.

Discrimination between ovine Babesia and Theileria species in China based on the ribosomal protein S8 (RPS8) gene.

Ovine babesiosis and theileriosis are important hemoprotozoal diseases of sheep and goats in tropical and subtropical regions that lead to economic losses in these animals. PCR-restriction fragment length polymorphism (PCR-RFLP) is a reliable molecular diagnostic tool for discriminating Theileria or Babesia species in the same host. In this study, the DNA sequences of a ribosomal protein S8 (RPS8) gene from four species of piroplasms in China were used to develop a species-specific PCR-RFLP diagnostic tool.

Cytochrome c oxidase subunit III (COX3) gene, an informative marker for phylogenetic analysis and differentiation of Babesia species in China.

In this study a 552-bp region of the cytochrome c oxidase subunit III (COX3) was amplified by polymerase chain reaction (PCR) and sequenced from individual Babesia species. Sequence variation between Babesia species from China ranged between 0 and 32.4%.

Phylogenetic analysis of Babesia species in China based on Cytochrome b (COB) gene.

In this study, a mitochondrial marker consisting of an approximately 550-bp region of the Cytochrome b genes (COB) was amplified by polymerase chain reaction (PCR) and sequenced from individual Babesia species. Sequence variation between Babesia species from China was 1.6-30.

First report on the occurrence of Rickettsia slovaca and Rickettsia raoultii in Dermacentor silvarum in China.

Background: Rickettsioses are among both the longest known and most recently recognized infectious diseases. Although new spotted fever group rickettsiae have been isolated in many parts of the world including China, Little is known about the epidemiology of Rickettsia pathogens in ticks from Xinjiang Autonomous Region of China.

Methods: In an attempt to assess the potential risk of rickettsial infection after exposure to ticks in Xinjiang Uygur Autonomous Region of China, a total of 200 Dermacentor silvarum ticks collected in Xinyuan district were screened by polymerase chain reaction based on the outer membrane protein A gene.
