Hypoxia inducible factor-1 (HIF-1α) reduced inflammation in spinal cord injury via miR-380-3p/ NLRP3 by Circ 0001723

Biol. Res; 53 (), 2020
BACKGROUND: Spinal cord injury (SCI) is a severe central nervous system trauma. The present study aimed to evaluate the effect of HIF-1α on inflammation in spinal cord injury (SCI) to uncover the molecular mechanisms of anti-inflammation. RESULTS: HIF-1α was reduced in SCI model rats and HIF-1α activa...

Characterising ISWI chromatin remodeler in Trypanosoma cruzi

Mem. Inst. Oswaldo Cruz; 115 (), 2020
BACKGROUND Imitation SWItch (ISWI) ATPase is the catalytic subunit in diverse chromatin remodeling complexes. These complexes modify histone-DNA interactions and therefore play a pivotal role in different DNA-dependent processes. In Trypanosoma cruzi, a protozoan that controls gene expression principall...

Silicon Mediated Alleviation of Salinity Stress Regulated by Silicon Transporter Genes (Lsi1 and Lsi2) in Indica Rice

Abstract Silicon accumulation is known to improve tolerance of plants under both biotic and abiotic stress. Salinity stress is an inevitable crisis causing wide spread damage to rice leading to food insecurity. The influence of Si (1mM) on two rice cultivars cv. Ghanteswari (high accumulator) and cv.Bada...

Nrf2, NF-κB and PPARβ/δ mRNA Expression Profile in Patients with Coronary Artery Disease

Arq. bras. cardiol; 113 (6), 2019
Abstract Background: Oxidative stress and inflammation are present in coronary artery disease (CAD) and are linked to the activation of the transcription nuclear factor kappa B (NF-κB). To attenuate these complications, transcription factors like nuclear factor erythroid 2-related factor 2 (Nrf2) a...

RNA-seq analysis of the response of plant-pathogenic oomycete Phytophthora parasitica to the fungicide dimethomorph

Rev. argent. microbiol; 51 (3), 2019
Phytophthora parasitica is an important oomycete that causes disease in a variety of plants, dimethomorph fungicides being specific for oomycetes. The aim of this study was to use RNA-seq to rapidly discover the mechanism by which dimethomorph acts in the treatment of P. parasitica. We found that the exp...

Therapeutic effects of dimethyldiguanide combined with clomifene citrate in the treatment of polycystic ovary syndrome

SUMMARY OBJECTIVE In view of the high incidence of polycystic ovary syndrome (PCOS) and the unsatisfactory therapeutic effects of dimethyldiguanide or clomifene citrate alone, our study aimed to investigate the therapeutic effects of dimethyldiguanide combined with clomifene citrate in the treatment of...

Inhibición del crecimiento y modificación genética de Phytophthora capsici usando quitosano de bajo grado de polimerización
Growth inhibition and genetic modification of Phytophthora capsici using chitosan with low degree of polymerization

Rev. argent. microbiol; 51 (1), 2019
Phytophtora capsici es un patógeno que incide sobre cultivos de la familia de las solanáceas causando pérdidas económicas en cultivos de pimientos, tomates, berenjenas y cur-cubitáceas. En este trabajo evaluamos el efecto del quitosano de bajo grado de polimerización (QBP) sobre el crecimiento de P...

MicroRNA en enfermedades autoinmunes

Gac. méd. Méx; 155 (1), 2019
Resumen Los microRNA (miRNA) son pequeños RNA no codificantes de aproximadamente 17 a 24 nucleótidos de longitud, los cuales se unen complementaria y principalmente en las regiones 3' UTR (región no traducida) de diversos RNA mensajeros (mRNA, messenger RNA). Su función general es regular negativamen...

Regulação da expressão de pioverdina dependente de contato em pseudomonas aeruginosa

A gama-proteobactéria Pseudomonas aeruginosa é um patógeno oportunista humano frequentemente associado a pacientes com queimadura grave e aos portadores de fibrose cística. O estabelecimento de infecção depende de uma série de fatores que contribuem para a virulência deste patógeno, dentre eles ...

Calpains of Leishmania braziliensis: genome analysis, differential expression, and functional analysis

Mem. Inst. Oswaldo Cruz; 114 (), 2019
BACKGROUND Calpains are proteins belonging to the multi-gene family of calcium-dependent cysteine peptidases that undergo tight on/off regulation, and uncontrolled proteolysis of calpains is associated with severe human pathologies. Calpain orthologues are expanded and diversified in the trypanosomatids...
