Smart Design of Mitochondria-Targeted and ROS-Responsive CPI-613 Delivery Nanoplatform for Bioenergetic Pancreatic Cancer Therapy.

Mitochondria, as the powerhouse of most cells, are not only responsible for the generation of adenosine triphosphate (ATP) but also play a decisive role in the regulation of apoptotic cell death, especially of cancer cells. Safe potential delivery systems which can achieve organelle-targeted therapy are urgently required. In this study, for effective pancreatic cancer therapy, a novel mitochondria-targeted and ROS-triggered drug delivery nanoplatform was developed from the TPP-TK-CPI-613 () prodrug, in which the ROS-cleave thioketal functions as a linker connecting mitochondrial targeting ligand TPP and anti-mitochondrial metabolism agent CPI-613.

Uncovering potential single nucleotide polymorphisms, copy number variations and related signaling pathways in primary Sjogren's syndrome.

Primary Sjogren's syndrome (pSS) is a complex systemic autoimmune disease, which is difficult to accurately diagnose due to symptom diversity in patients, especially at earlier stages. We tried to find potential single nucleotide polymorphisms (SNPs), copy number variations (CNVs) and related signaling pathways. Genomic DNA was extracted from peripheral blood of 12 individuals (7 individuals from 3 pSS pedigrees and 5 sporadic cases) for whole-exome sequencing (WES) analysis.

Demethylzeylasteral (T-96) initiates extrinsic apoptosis against prostate cancer cells by inducing ROS-mediated ER stress and suppressing autophagic flux.

Mitigated reactive oxygen species generation leads to an improvement of cell proliferation on poly[glycidyl methacrylate-co-poly(ethylene glycol) methacrylate] functionalized polydimethylsiloxane surfaces.

In vitro cell-based analysis is strongly affected by material's surface chemical properties. The cell spreading, migration, and proliferation on a substrate surface are initiated and controlled by successful adhesion, particularly for anchor-dependent cells. Unfortunately, polydimethylsiloxane (PDMS), one of the most used polymeric materials for construction of microfluidic and miniaturized biomedical analytic devices, is not a cell-friendly surface because of its inherent hydrophobic property.

Involvement of superoxide and nitric oxide in BRAF(V600E) inhibitor PLX4032-induced growth inhibition of melanoma cells.

The BRAF(V600E) inhibitor PLX4032 (Vemurafenib) is an FDA-approved new drug for the treatment of metastatic melanomas, which specifically inhibits the RAS/MEK/ERK signaling pathway to control cell proliferation and adhesion. However, no study has been carried out to investigate the role of intracellular oxidative balance in PLX4032-induced tumor growth inhibition. Herein, for the first time, superoxide (O2˙(-)) and nitric oxide (NO) generated from PLX4032-challenged melanoma cells were monitored using electrochemical sensors and conventional fluorescein staining techniques.

Early biochemical response to ursodeoxycholic acid and long-term prognosis of primary biliary cirrhosis: results of a 14-year cohort study.

Unlabelled: The biochemical response to ursodeoxycholic acid (UDCA) in primary biliary cirrhosis is a strong predictor of long-term outcome and thus facilitates the rapid identification of patients needing new therapeutic approaches. Numerous criteria for predicting outcome of treatment have been studied based on biochemical response to UDCA at 1 year. We sought to determine whether an earlier biochemical response at 3 or 6 months could as efficiently identify patients at risk of poor outcome, as defined by liver-related death, liver transplantation, and complications of cirrhosis.

The clinical and laboratory data were collected at 0, 3, 6 and 12 months after treatment.

High mobility group box 1 induces synoviocyte proliferation in rheumatoid arthritis by activating the signal transducer and activator transcription signal pathway.

Recently, it was discovered that high mobility group box chromosomal protein 1 (HMGB1) acts as a potent pro-inflammatory cytokine that is released into the extracellular milieu. Signal transducer and activator of transcription (STAT) proteins play an important role in cytokine signaling. Some investigators have reported preferential activation of STAT1, and others have reported preferential activation of STAT3 in response to endogenous interleukin-6 (IL-6) in patients with rheumatoid arthritis.

Interstitial lung disease and Sjögren's syndrome in primary biliary cirrhosis: a causal or casual association?

Interstitial lung disease (ILD) has been reported in patients with primary biliary cirrhosis (PBC); however, its frequency and pathogenesis are still poorly documented. Sjogren's syndrome (SS) is fairly common among patients with PBC, but the relationship between SS and PBC also remains controversial. To determine whether ILD and SS in PBC is a causal or casual association, whether SS accompanying PBC, could be considered secondary to or associated with PBC.

Antimitochondrial antibody-negative primary biliary cirrhosis: a subset of primary biliary cirrhosis.

Objective: Antimitochondrial antibodies (AMA) are the hallmark in primary biliary cirrhosis (PBC); nevertheless, it has long been recognized that 5-10% patients with typical features compatible with PBC do not have detectable AMA, and they were referred to as 'AMA-negative PBC'. This study aimed to evaluate whether AMA-negative/positive PBC represents different clinical entities.

Methods: We compared the clinical, laboratory, percentage of regulatory T cells (Tregs) in peripheral blood, liver biopsy features and response to treatment of the two groups of patients.
