Although anti-PD-1/PD-L1 antibodies represent a major breakthrough in NSCLC patients’ survival, this treatment efficacy is highly dependent on tumor PD-L1 expression. We reported the role of Id1 and combined blockade PD-1-Id1 KRAS mutant mouse model [Baraibar, Cancers 2020]. Trametinib, an oral MEK1/2 inhibitor, acts downstream KRAS. Here we evaluate trametinib as inhibitor able to enhance immu...

Abstract Introduction Neurons in the pre-Bötzinger complex are critical for generation of inspiratory rhythm and control activity genioglossus muscle via activation hypoglossal motoneurons. Activation causes anterior movement tongue widens upper airway. As obstructive sleep apnea (OSA) is associated with obstruction airway, this neuronal pathway may be a novel therapeutic approach. Orexins have...

Aquaporin-1 (AQP1) is a proangiogenic water channel protein promoting endothelial cell migration. We previously reported that AQP1 silencing by RNA interference reduces angiogenesis-dependent primary tumour growth in a mouse model of melanoma. In this study, we tested the hypothesis that AQP1 inhibition also affects animal survival and lung nodule formation. Melanoma was induced by injecting B1...

Insulin exerts its potent effects on hepatic glucose fluxes via direct and indirect mechanisms. Whereas a liver-specific insulin receptor (IR) knockout (LIRKO) mouse exhibits glucose intolerance as well as insulin resistance, it is unclear whether a more acute decrease in the expression of hepatic IR would be sufficient to induce hepatic insulin resistance. Here we report that the downregulatio...

A diet high in fat induces cardiac hypertrophy, inflammation, and oxidative stress. Although such actions have largely been ascribed to fat deposition, the accumulation of advanced glycation end products (AGEs) and subsequent activation of the receptor for AGEs (RAGE) may also represent important mediators of cardiac injury following exposure to a Western diet. In this study, male C57BL6J and R...

Circadian rhythms are integral to the normal functioning of numerous physiological processes. Evidence from human and mouse studies suggests that loss of rhythm occurs in obesity and cardiovascular disease and may be a neglected contributor to pathophysiology. Obesity has been shown to impair the circadian clock mechanism in liver and adipose tissue but its effect on cardiovascular tissues is u...

BACKGROUND Gal-geun-dang-gwi-tang (GGDGT), an herbal medicine, is used to treat hypertension, stroke, and other inflammatory disorders in the clinical setting. Recently, GGDGT was recognized by the Korea Institute of Oriental Medicine. This study aimed to evaluate the effects of GGDGT in a diabetic atherosclerosis model using apolipoprotein E knockout (ApoE-/-) mice fed a Western diet. METHOD...

Intestinal epithelial cell damage is frequently seen in the mucosal lesions of inflammatory bowel diseases such as ulcerative colitis or Crohn's disease. Complete remission of these diseases requires both the cessation of inflammation and the migration of enterocytes to repair the damaged epithelium. Lyophilized Saccharomyces boulardii (Sb, Biocodex) is a nonpathogenic yeast widely used as a th...
