Alteração na representação de subpopulações de neurônios no epitélio olfatório de camundongos Ric8b cKO

O objetivo desse trabalho foi identificar as consequências moleculares e funcionais da falta da proteína Ric8b no epitélio olfatório de camundongos. Para esse fim, comparamos o transcriptoma de epitélio olfatório de camundongos knock-out tecido específico para a proteína RIC8B (Ric8b cKO) com o d...

Effect of long-term consumption of oxidized polyunsaturated fatty acids on atherosclerotic lesion in LDL receptor knockout mice

Polyunsaturated fatty acids (PUFA) are susceptible to enzymatic and non-enzymatic oxidation, leading to the production of secondary compounds that present different physiological effects. Among the PUFA, the products formed from Omega 6 (n-6 FA) and Omega 3 (n-3 FA) fatty acids oxidation can modulate inf...

Remodelado cardíaco en el modelo preclínico de falla cardíaca isquémica experimental por dislipidemia en el ratón SR-B1 KO/ApoER6 1h/h

Rev. chil. cardiol; 39 (1), 2020
INTRODUCCIÓN: Los ratones SR-B1 KO/ApoER6 1h/h que son alimentados con una dieta rica en grasas saturadas, desarrollan enfermedad coronaria aterosclerótica severa, complicaciones isquémicas e insuficiencia cardíaca, con alta mortalidad. Los estudios con este modelo se han enfocado fundamentalmente e...

Effects of Physical Training on the Myocardium of Oxariectomized LDLr Knockout Mice: MMP 2/9, Collagen I/III, Inflammation and Oxidative Stress

Arq. bras. cardiol; 114 (1), 2020
Abstract Background: The emergence of coronary heart disease is increased with menopause, physical inactivity and with dyslipidemia. Physical training is known to promote the improvement of cardiovascular functions. Objective: To investigate the effects of aerobic physical training on the left ventricl...

Effects of Rab7 gene up-regulation on renal fibrosis induced by unilateral ureteral obstruction

Braz. j. med. biol. res; 53 (4), 2020
Rab7, an important member of the Rab family, is closely related to autophagy, endocytosis, apoptosis, and tumor suppression but few studies have described its association with renal fibrosis. In the early stage, our group studied the effects of Rab7 on production and degradation of extracellular matrix i...

Knockdown of lncRNA TUG1 inhibits hippocampal neuronal apoptosis and participates in aerobic exercise-alleviated vascular cognitive impairment

Biol. Res; 53 (), 2020
OBJECTIVES: Our previous study indicated that aerobic exercise relieves cognitive impairment in patients with vascular cognitive impairment (VCI) via regulating brain-derived neurotrophic factor (BDNF), but the mechanism is not yet clear. This study aimed to explore whether lncRNA taurine upregulated gen...

New insights of growth hormone (GH) actions from tissue-specific GH receptor knockouts in mice

ABSTRACT In order to provide new insights into the various activities of GH in specific tissues, recent advances have allowed for the generation of tissue-specific GHR knockout mice. To date, 21 distinct tissue-specific mouse lines have been created and reported in 28 publications. Targeted tissues inclu...

The liver injury following ischemia and reperfusion is worse in experimental knockout heterozygote mouse model for expression of connexin 43

Acta cir. bras; 34 (10), 2019
Abstract Purpose: To evaluate that Connexin (Cx43) plays a role in lesions after hepatic ischemia/reperfusion (IR) injury. Methods: We use Cx43 deficient model (heterozygotes mice) and compared to a wild group. The groups underwent 1 hour ischemia and 24 hours reperfusion. The heterozygote genotype was...

Knockdown of transglutaminase-2 prevents early age-induced vascular changes in mice

Acta cir. bras; 33 (11), 2018
Abstract Purpose: To determine whether the absence of transglutaminase 2 enzyme (TG2) in TG2 knockout mice (TG2-/-) protect them against early age-related functional and histological arterial changes. Methods: Pulse wave velocity (PWV) was measured using non-invasive Doppler and mean arterial pressure...
