Article Synopsis
  • * Tyrosine kinase inhibitors (TKIs) are a key treatment for advanced RCC, but some patients develop resistance, prompting research into combining TKIs with targeted metabolic therapies.
  • * The study identified DEPDC1 as a significant factor in promoting RCC progression and resistance, suggesting it could be a new target for improved treatment strategies in resistant cases.

Article Synopsis
  • Multiwalled carbon nanotubes (MWCNTs) are being studied for their potential use in drug delivery and medical imaging, but their impact on blood vessel cells (endothelial cells) hasn't been fully understood.
  • The research revealed that MWCNTs can enter these cells and disrupt their functions, specifically hindering their ability to form new blood vessels (angiogenesis) in both lab and animal studies.
  • The study found that the harmful effects of MWCNTs on endothelial cells are linked to decreased levels of vascular endothelial growth factor (VEGF), but introducing recombinant VEGF can help restore cell function and promote angiogenesis.

Psoriasis is characterized by keratinocyte proliferation and immune cell infiltration. M2 isoform of pyruvate kinase (PKM2) was reported to have an important role in cell proliferation, which is a rate-limiting enzyme that regulates the final step of glycolysis. However, how PKM2 regulates cell metabolism and proliferation in psoriatic keratinocytes is still poorly understood.

Background: Renal cell carcinoma (RCC) is one of the most common malignant tumors originating from the renal parenchymal urinary epithelial system. Tripartite motif 47 (TRIM47) is a member of the TRIM family proteins, which has E3 ligase activity and has been demonstrated to be involved in the occurrence and prognosis of many tumors. The main purpose of this study is to explore the role and potential mechanism of TRIM47 in promoting malignant biological behavior of RCC.

This study tested the hypothesis that endothelium-specific GTP cyclohydrolase I (GTPCH I) overexpression (Tg-GCH) restores age-associated endothelial dysfunction in vivo. Aortic GTPCH I expression and serum nitric oxide (NO) release were measured in young and aged mice. Aortic rings from young and aged wild-type (WT) mice and aged Tg-GCH mice were suspended for isometric tension recording.

Added risk portended by diabetes in addition to hypertension has been related to an amplification of endothelial dysfunction. β-blockers are widely used for cardiovascular diseases and improve the endothelial function compared with a placebo. However, the effect of β-blockers on the endothelial progenitor cells (EPCs) function in diabetes is still unknown.

Resistance to radiotherapy causes non-small cell lung cancer (NSCLC) treatment failure associated with local recurrence and metastasis. Thus, understanding the radiosensitization of NSCLC cells is crucial for developing new treatments and improving prognostics. mTORC1 has been shown to regulate tumor cell radiosensitivity, but the underlying mechanisms are unclear.

Functional characterization of disease-causing variants at risk loci has been a significant challenge. Here we report a high-throughput single-nucleotide polymorphisms sequencing (SNPs-seq) technology to simultaneously screen hundreds to thousands of SNPs for their allele-dependent protein-binding differences. This technology takes advantage of higher retention rate of protein-bound DNA oligos in protein purification column to quantitatively sequence these SNP-containing oligos.

Objective: To observe the clinical effects of arthroscopy-guided core decompression and bone grafting combined with selective arterial infusion for early stage avascular necrosis of femoral head.

Methods: From January 2010 to December 2014, 76 patients(76 hips) diagnosed as Ficat II stage avascular necrosis of femoral head were randomly divided into experimental group and control group. In the experimental group, there were 27 males and 8 females aged from 24 to 55 years old with an average of (43.

Background: Proprotein convertase subtilisin/kexin type 9 (PCSK9) is a protein expressed primarily in the liver, formerly known to maintain plasma lipid homeostasis by regulating low-density lipoprotein receptor levels, and its exact role in the radioresistance of prostate cancer (PCa) remains unclear. We aim to investigate the function of PCSK9 in the radioresistance of PCa cells.

Methods: PCSK9 small interfering RNA (siRNA) was introduced into the PCa cells by transient transfection.

Sineoculis homeobox homolog (SIX) family proteins, including SIX1, SIX2, SIX3, SIX4, SIX5, and SIX6, have been implicated in the initiation and progression of breast cancer, but the role of each member in breast tumor is not fully understood. We conducted a systematic review and meta-analysis to evaluate the association between the mRNA levels of all 6 members and clinic-pathological characteristics and clinical outcome of breast cancer patients based on the PRISMA statement criteria.ArrayExpress and Oncomine were searched for eligible databases published up to December 10, 2015.

Background: We have recently proved electroacupuncture (EA) ST36 exerted an anti-inflammatory effect in the early phase of intra-abdominal adhesion formation. Evidences indicate that the anti-inflammatory effect of EA ST36 involves a cholinergic anti-inflammatory pathway-dependent mechanism via the vagus nerve. However, the exact effects and accurate vagal modulation of acupuncture in prevention of postoperative intra-abdominal adhesion formation has not been thoroughly evaluated.

The cis-epoxysuccinate hydrolases (CESHs), members of epoxide hydrolase, catalyze cis-epoxysuccinic acid hydrolysis to form D: (-)-tartaric acid or L: (+)-tartaric acid which are important chemicals with broad scientific and industrial applications. Two types of CESHs (CESH[D: ] and CESH[L: ], producing D: (-)- and L: (+)-tartaric acids, respectively) have been reported with low yield and complicated purification procedure in previous studies. In this paper, the two CESHs were overexpressed in Escherichia coli using codon-optimized genes.

Aim: To investigate the effect of carbachol on gastrointestinal function in a dog model of oral resuscitation for burn shock.

Methods: Twenty Beagle dogs with intubation of the carotid artery, jugular vein and jejunum for 24 h were subjected to 35% total body surface area full-thickness burns, and were divided into three groups: no fluid resuscitation (NR, n = 10), in which animals did not receive fluid by any means in the first 24 h post-burn; oral fluid resuscitation (OR, n = 8), in which dogs were gavaged with glucose-electrolyte solution (GES) with volume and rate consistent with the Parkland formula; and oral fluid with carbachol group (OR/CAR, n = 8), in which dogs were gavaged with GES containing carbachol (20 μg/kg), with the same volume and rate as the OR group. Twenty-four hours after burns, all animals were given intravenous fluid replacement, and 72 h after injury, they received nutritional support.
