[Effect of simplified formula of Jinfukang Oral Liquid on apoptosis of renal tubular epithelial cells induced by cisplatin].

In order to study the effect of the simplified formula of Jinfukang Oral Liquid(ALG-12) on renal tubular injury induced by cisplatin(DDP), 48 C57 mice were divided into control group, model group, DDP group, and DDP combined with low, medium, and high dose groups of ALG-12. The mice were administered for 16 days after the establishment of the subcutaneous Lewis lung cancer heterotopic transplant tumor model of mice. The pathological changes, serum creatinine(Scr), blood urea nitrogen(BUN), kidney injury molecule 1(Kim-1), neutrophil gelatinase-associated lipocalin(NGAL), malondialdehyde(MDA), and total superoxide dismutase(T-SOD) in renal tissue and the degree of renal tubular cell apoptosis were analyzed to investigate the effect of ALG-12 on renal injury induced by DDP treatment on non-small cell lung cancer(NSCLC).

Low-Toxicity and High-Efficiency Genome Editing Tool Based on the Miniature Type V-F CRISPR/Cas Nuclease AsCas12f1.

Genome editing tools based on SpCas9 and FnCpf1 have facilitated strain improvements for natural product production and novel drug discovery in . However, due to high toxicity, their editing requires high DNA transformation efficiency, which is unavailable in most streptomycetes. The transformation efficiency of an all-in-one editing tool based on miniature Cas nuclease AsCas12f1 was significantly higher than those of SpCas9 and FnCpf1 in tested streptomycetes, which is due to its small size and weak DNA cleavage activity.

GPCR signaling contributes to immune characteristics of microenvironment and process of EBV-induced lymphomagenesis.

Epstein-Barr virus (EBV) is the oncogenic driver of multiple cancers. However, the underlying mechanism of virus-cancer immunological interaction during disease pathogenesis remains largely elusive. Here we reported the first comprehensive proteogenomic characterization of natural killer/T-cell lymphoma (NKTCL), a representative disease model to study EBV-induced lymphomagenesis, incorporating genomic, transcriptomic, and in-depth proteomic data.

Development of a CRISPR/Cas9 Nickase (nCas9)-Mediated Genome Editing Tool in .

Streptomycetes have a strong ability to produce a vast array of bioactive natural products (NPs) widely used in agriculture and veterinary/human medicine. The recently developed CRISPR/Cas9-based genome editing tools have greatly facilitated strain improvement for target NP overproduction as well as novel NP discovery in . However, CRISPR/Cas9 shows high toxicity to the host, limiting its application in many strains with a low DNA transformation efficiency.

Objective: To analyze the relationship of the expression of transcription factor MYB targeted regulation by miR-96 to cell invasion and apoptosis in pediatric acute myeloid leukemia (AML).

Methods: A total of 65 children with AML in The 928 Hospital of PLA Joint Logistics Support Forces from January 2017 to November 2019 were selected, including 35 cases diagnosed as primary AML and 30 cases as complete remission AML. Thirty children with immune thrombocytopenia were selected as control group.

Biosynthesis of a ganoderic acid in Saccharomyces cerevisiae by expressing a cytochrome P450 gene from Ganoderma lucidum.

Ganoderic acid (GA), a triterpenoid from the traditional Chinese medicinal higher fungus Ganoderma lucidum, possesses antitumor and other significant pharmacological activities. Owing to the notorious difficulty and immaturity in genetic manipulation of higher fungi as well as their slow growth, biosynthesis of GAs in a heterologous host is an attractive alternative for their efficient bioproduction. In this study, using Saccharomyces cerevisiae as a host, we did a systematic screening of cytochrome P450 monooxygenase (CYP450) gene candidates from G.

HSP70-Hrd1 axis precludes the oncorepressor potential of N-terminal misfolded Blimp-1s in lymphoma cells.

B lymphocyte-induced maturation protein-1 (Blimp-1) ensures B-cell differentiation into the plasma cell stage, and its instability constitutes a crucial oncogenic element in certain aggressive cases of activated B cell-like diffuse large B-cell lymphoma (ABC-DLBCL). However, the underlying degradation mechanisms and their possible therapeutic relevance remain unexplored. Here, we show that N-terminal misfolding mutations in ABC-DLBCL render Blimp-1 protein susceptible to proteasome-mediated degradation but spare its transcription-regulating activity.

Evolution of saturated hydraulic conductivity with compression and degradation for municipal solid waste.

Municipal solid waste (MSW) specimens were created from synthetic fresh MSW degraded in a laboratory scale enhanced degradation reactor. The degree of degradation and saturated hydraulic conductivity k were measured to study the effects of compression and degradation on k of MSW. The degree of degradation was characterized through the ratio of cellulose content to lignin content (i.

Rosiglitazone elevates sensitization of drug-resistant oral epidermoid carcinoma cells to vincristine by G2/M-phase arrest, independent of PPAR-γ pathway.

Rosiglitazone (ROSI), an oral antidiabetic agent, has been reported the anti-cancer properties recent years. In this paper, the potency of ROSI as a synergistic drug for vincristine (VCR) on resistant oral cancer cells was investigated. We found that ROSI potently enhanced the susceptibility of KB cells or KB/V cells to VCR in a dose manner and the synergy in KB/V cells was much more prominent than that in KB cells.

Reactive oxygen species mediate oridonin-induced apoptosis through DNA damage response and activation of JNK pathway in diffuse large B cell lymphoma.

This study investigated the cytotoxic effect of oridonin (ORI), a diterpenoid isolated from Rabdosia rubescens, in human diffuse large B cell lymphoma (DLBCL) in vitro and in vivo and the potential molecular mechanisms for ORI-induced cell apoptosis. ORI treatment caused reactive oxygen species (ROS)-mediated oxidative DNA damage response (DDR) and the c-Jun N-terminal kinase (JNK) pathway activation, leading to an induction of intrinsic apoptosis. ROS abolition blocked ORI-induced apoptosis and attenuated the expression of phospho-histone H2AX and phospho-JNK, indicating that ROS-mediated DNA damage and JNK pathway activation were involved in ORI-induced apoptosis.

Effect of one month duration ketogenic and non-ketogenic high fat diets on mouse brain bioenergetic infrastructure.

Diet composition may affect energy metabolism in a tissue-specific manner. Using C57Bl/6J mice, we tested the effect of ketosis-inducing and non-inducing high fat diets on genes relevant to brain bioenergetic infrastructures, and on proteins that constitute and regulate that infrastructure. At the end of a one-month study period the two high fat diets appeared to differentially affect peripheral insulin signaling, but brain insulin signaling was not obviously altered.

A tetramethylpyrazine piperazine derivate CXC137 prevents cell injury in SH-SY5Y cells and improves memory dysfunction of rats with vascular Dementia.

We investigated the effects of CXC137, a tetramethylpyrazine piperazine derivate, on cell damage induced by N-methyl-D-aspartate (NMDA) in human derived neuroblastoma cells (SH-SY5Y) and its effect on memory dysfunction of rats with vascular dementia. It was found that the presence of CXC137 increased SH-SY5Y cells viability by inhibition of cell apoptosis induced by NMDA. These effects of CXC137 were accompanied by increases of the antioxidant superoxide dismutase activity and the level of reduced glutathione, and a decrease of lipid peroxidation product, malondialdehyde.

Combination of rituximab and mammalian target of rapamycin inhibitor everolimus (RAD001) in diffuse large B-cell lymphoma.

Abstract We evaluated the efficacy of the anti-CD20 monoclonal antibody rituximab in combination with the mammalian target of rapamycin (mTOR) inhibitor everolimus for treating diffuse large B-cell lymphoma (DLBCL). The combination of rituximab and everolimus was more effective for inhibiting cell growth compared with single-agent therapy. An increase in G0/G1 cell cycle arrest and an increased population of cells in apoptosis were observed in the combination treatment group.

Activation of the PI3K/AKT/mTOR pathway in diffuse large B cell lymphoma: clinical significance and inhibitory effect of rituximab.

Diffuse large B cell lymphoma (DLBCL) represents the most common subtype of non-Hodgkin lymphoma and accounts for approximately 30% of newly diagnosed lymphoid neoplasms in Western countries, and 40-50% in China. A better understanding of the biology of DLBCL is needed for the development of potential therapeutic agents that target specific intracellular pathways. In this study, expression of the important components of the phosphatidylinositol 3-kinase (PI3K)/AKT/mammalian target of rapamycin (mTOR) signaling pathway and their clinical significance were investigated in 73 DLBCL cases.

Ncb5or deficiency increases fatty acid catabolism and oxidative stress.

The endoplasmic reticulum-associated NADH cytochrome b(5) oxidoreductase (Ncb5or) is widely distributed in animal tissues. Ncb5or(-/-) mice develop diabetes at age 7 weeks and have increased susceptibility to the diabetogenic oxidant streptozotocin. Ncb5or deficiency also results in lipoatrophy and increased hepatocyte sensitivity to cytotoxic effects of saturated fatty acids.
