TGFbeta regulates cellular processes by binding to type I and type II TGFbeta receptors (TbetaRI and TbetaRII, respectively). In addition to these signaling receptors, endoglin is an accessory TGFbeta receptor that regulates TGFbeta signaling. Although there are two different alternatively spliced isoforms of endoglin, L-endoglin (L, long) and S-endoglin(More)
A study was undertaken to examine the effects of inulin, alone or in combination with enzyme complex (primarily xylanase and beta-glucanase), on growth performance, ileal and cecal microflora, cecal short-chain fatty acids, and d-lactic acid and jejunal histomorphology of broiler chickens fed a wheat- and barley-based diet from 7 to 35 d of age. A total of(More)
Senescence of endothelial cells (ECs) may contribute to age-associated cardiovascular diseases, including atherosclerosis and hypertension. The functional and gene expression changes associated with cellular senescence are poorly understood. Here, we have analyzed the expression, during EC senescence, of 2 different isoforms (L, long; S, short) of endoglin,(More)
Sirtuin 1 (Sirt1) and Sirtuin 2 (Sirt2) belong to the family of NAD+ (nicotinamide adenine dinucleotide-positive)-dependent class III histone deacetylases and are involved in regulating lifespan. As cancer is a disease of ageing, targeting Sirtuins is emerging as a promising antitumour strategy. Here we present Salermide(More)
Transforming growth factor-beta1 (TGF-beta1) plays a fundamental role in the progression of renal diseases. Accumulating evidence has suggested that eicosanoids derived from cyclooxygenase-2 (COX-2) participate in a number of pathological processes in immune-mediated renal diseases. Mesangial cells (MC) play a major role in physiological and(More)
Low-level lead exposure is a known cause of hypertension that has been associated with increased reactive oxygen species activity and endothelial-dependent vasorelaxation impairment. The effect of lead exposure on the vascular nitric oxide (NO)/cyclic guanocine monophosphate (cGMP) system was analyzed. Wistar rats were exposed to 5 ppm lead acetate in the(More)
A study was conducted to evaluate the effect of adding inulin to diets containing 2 different types of fat as energy sources on performance, blood serum metabolites, liver lipids, and fatty acids of abdominal adipose tissue and breast and thigh meat. A total of 240 one-day-old female broiler chicks were randomly allocated into 1 of 6 treatments with 8(More)
Two kinds of feed (commercial concentrate vs whole supplemented barley) were compared in unweaned lambs and lambs weaned at 40 days of age, fattened at pasture and slaughtered at 28 kg live weight, in order to observe their effects on meat quality and fatty acid composition. The weaning status influenced fatness; unweaned lambs displayed a greater carcass(More)
BACKGROUND Mesangial activation occurs in many forms of renal disease that progress to renal failure. Mitogen-activated protein kinases (MAPKs) are important mediators involved in the intracellular network of interacting proteins that transduce extracellular stimuli to intracellular responses. The extracellular signal-regulated kinases 5 (Erk5) MAPK pathway(More)
Eighty-six male light lambs of Manchego breed were used in this study. Principal component (PC) analysis was performed to study the relationship between carcass quality variables (n=22) and between meat quality measures (n=21). The carcass quality was assessed using objective and subjective measurements of conformation and fatness besides the joints(More)
