(2018)"Regulating activities of -amylase and -glucosidase through the use of specific inhibitors is a main strategy for controlling type 2 diabetes. Smilax aristolochiifolia root decoctions are traditionally used in Mexico as ... -
Identificación de los sitios de unión al ATP en receptores P2X1 de humanos.
(2018-12)"Los receptores P2X son canales catiónicos no selectivos activados por trifosfato de adenosina (ATP), involucrados en diversos procesos fisiológicos como neurotransmisión, nocicepción e inflamación. La determinación de ... -
Caracterización electrofisiológica de receptores hP2X1 y hP2X1del coexpresados en ovocitos de Xenopus laevis
(2018-12)"Los leucocitos humanos liberan nucleótidos, incluyendo ATP, que al unirse a receptores purinérgicos, son capaces de desencadenar diferentes procesos celulares, incluyendo la muerte de patógenos. El estudio de los ... -
Microbiome characterization of the escamolera ants unveils microorganisms with high biotechnological potential
(2018-12)"Insects have adapted to several ecosystems through the versatility of their feeding habits, wherein their intestinal microbiota has played a key role in the biological processes canalization. Liometopum apiculatum ant is ... -
Detección molecular de cuatro especies comunes de Candida a partir de hemocultivos
(2018-11)"En este trabajo empleamos oligonucleótidos diseñados en el IPICYT para amplificar secuencias genómicas específicas de las cuatro especies principales causantes de candidemia. Realizamos la identificación de 194 aislados ... -
Caracterización bioquímica y estructural del factor de transcripción Clp y del complejo Clp/ADN
(2018-11)"Las bacterias del género Xanthomonas son de un alto interés agrícola y económico, a causa de que son bacterias fitopatógenas y por lo tanto responsables de enfermedades en plantas como la podredumbre negra o cáncer, en ... -
Expresión heteróloga de péptidos antiangiogénicos en Pichia pastoris
(2018-09)"La vasostatina (Vs30) y la vasoinhibina (Vi-II-14.1) son péptidos inhibidores de la angiogénesis que son derivados de la región N-terminal de la calreticulina y la prolactina humana, respectivamente. Anteriormente, Vs30, ... -
Hetero- and homodimerization of Arabidopsis thaliana arginine decarboxylase AtADC1 and AtADC2
(Elsevier B.V., 2017-03)"The arginine decarboxylase enzyme (ADC) carries out the production of agmatine from arginine, which is the precursor of the first polyamine (PA) known as putrescine; subsequently, putrescine is turned into the higher PAs, ... -
Modification of AtGRDP1 gene expression affects silique and seed development in Arabidopsis thaliana
(Elsevier B.V., 2017-04)"Glycine Rich Proteins (GRPs) are induced at different developmental stages and in specific plant tissues. Recently, we described a novel Arabidopsis gene encoding a short glycine-rich domain protein (AtGRDP1). This gene ... -
Arabidopsis thaliana sucrose phosphate synthase (sps) genes are expressed differentially in organs and tissues, and their transcription is regulated by osmotic stress
(Elsevier B.V., 2017-11)"Sucrose is synthesized from UDP-Glc and Fru-6-phosphate via the activity of sucrose-phosphate synthase (SPS) enzymes, which produce Suc-6-phosphate. Suc-6-phosphate is rapidly dephosphorylated by phosphatases to produce ... -
