Effects of baicalin on inflammatory reaction, oxidative stress and PKDl and NF-kB protein expressions in rats with severe acute pancreatitis

Acta cir. bras; 33 (7), 2018
Abstract Purpose: To investigate the effects of baicalin on inflammatory reaction, oxidative stress and protein kinase D1 (PKD1) and nuclear factor-kappa B (NF-κB) protein expressions in severe acute pancreatitis (SAP) rats. Methods: Sixty rats were divided into sham operation, model, and low-, m...

Interleukin-4 protects from chemotherapy-induced peripheral neuropathy in mice modal via the stimulation of IL-4/STAT6 signaling

Acta cir. bras; 33 (6), 2018
Abstract Purpose: To investigate the possible role of IL-4 signaling pathway in vincristine-induced peripheral neuropathy. Methods: The mouse model of vincristine-induced peripheral neuropathy and interleukin (IL)-4 knockout mice were utilized to investigate the possible role of IL-4 signaling pathwa...

Impact of Bacille Calmette-Guérin revaccination on serum IgE levels in a randomized controlled trial

Abstract INTRODUCTION: Bacille Calmette-Guérin (BCG) downmodulates allergen-specific IgE levels and prevents other atopic responses in experimental models but fails to protect against respiratory allergies. Human responsiveness to BCG is variable and may interfere with protection. METHODS: Multivari...

Insights on the epigenetic mechanisms underlying pulmonary arterial hypertension

Braz. j. med. biol. res; 51 (12), 2018
Pulmonary arterial hypertension (PAH), characterized by localized increased arterial blood pressure in the lungs, is a slow developing long-term disease that can be fatal. PAH is characterized by inflammation, vascular tone imbalance, pathological pulmonary vascular remodeling, and right-sided heart fail...

Baicalein alleviates tubular-interstitial nephritis in vivo and in vitro by down-regulating NF-κB and MAPK pathways

Braz. j. med. biol. res; 51 (10), 2018
Tubular-interstitial nephritis (TIN) is characterized by tubular cell damage and inflammatory lesions of kidneys. Baicalein (BAI) is a flavonoid compound found in the roots of Scutellaria baicalensis Georgi. The present study was undertaken to explore the anti-inflammatory and anti-oxidative effects of B...

Knockdown of long non-coding RNA ANRIL inhibits tumorigenesis in human gastric cancer cells via microRNA-99a-mediated down-regulation of BMI1

Braz. j. med. biol. res; 51 (10), 2018
Long non-coding RNA antisense non-coding RNA in the INK4 locus (ANRIL) has been reported to promote tumorigenesis via regulating microRNA (miR)-99a in gastric cancer cells. However, the role of each component involved in it is still not well understood. This study aimed to verify the role of ANRIL in gas...

Down-regulated miR-448 relieves spinal cord ischemia/reperfusion injury by up-regulating SIRT1

Braz. j. med. biol. res; 51 (5), 2018
MicroRNAs play a crucial role in the progression of spinal cord ischemia/reperfusion injury (SCII). The role of miR-448 and SIRT1 in SCII was investigated in this study, to provide further insights into prevention and improvement of this disorder. In this study, expressions of miR-448 and SIRT1 protein w...

Expression of tumor suppressors miR-195 and let-7a as potential biomarkers of invasive breast cancer

Clinics; 73 (), 2018
OBJECTIVE: MicroRNAs (miRNAs) are small non-coding RNAs that regulate gene expression at the posttranscriptional level. Some miRNAs, including let-7a and miR-195, have been described as tumor suppressors. However, the roles of these microRNAs in breast cancer progression remain controversial. The aim of ...

Independent prognostic genes and mechanism investigation for colon cancer

Biol. Res; 51 (), 2018
PROPOSE: We aimed to explore the potential molecular mechanism and independent prognostic genes for colon cancer (CC). METHODS: Microarray datasets GSE17536 and GSE39582 were downloaded from Gene Expression Omnibus. Meanwhile, the whole CC-related dataset were downloaded from The Cancer Genome Atlas (TCG...

MicroRNA-1247 inhibits cell proliferation by directly targeting ZNF346 in childhood neuroblastoma

Biol. Res; 51 (), 2018
BACKGROUND: Neuroblastoma (NB) represents the most common extracranial solid tumor in children. Accumulating evidence shows that microRNAs (miRs) play an important role in the carcinogenesis of NB. Here, we investigated the biological function of miR-1247 in NB in vitro. METHODS/RESULTS: We found miR-12...
