IS THE ERA OF CANDIDATE GENES X CANNABIS USE REALLY DEAD?
2019
Background: Historically, gene X environment examinations in psychotic disorders have employed candidate gene methods and environmental determinants impacting on similar biological mechanisms. However, genome wide association studies (GWAS) show that many variants associated with schizophrenia have a modest effect size on risk. In this respect, it is unclear whether the effect of cannabis on psychosis phenotypes is modified by a few genes, e.g. those involved in dopamine signalling, or by the overall genetic susceptibility to schizophrenia. Indeed, candidate gene approaches might be complementary to GWAS to test gene X cannabis interaction. We aimed to investigate the interactive effects of…
Estudio del receptor 2 de la dopamina en ovario humano y efecto de su modulación sobre el Síndrome de Hiperestimulación Ovárica
2012
El síndrome de hiperestimulación ovárica (SHO) es una complicación iatrogénica derivada del uso de gonadotropinas exógenas para la inducción de la ovulación que cursa durante la fase lútea o el embarazo, pudiendo causar graves efectos sobre la salud e incluso la muerte. El uso de agonistas del receptor 2 de la dopamina (DrD2) se ha visto efectivo en el tratamiento de SHO, sin embargo tan solo se obtienen resultados beneficiosos en el 50% de los casos de SHO temprano, mientras que es totalmente inefectivo en los casos de SHO tardío. Para tratar de establecer los mecanismos moleculares que dan lugar a esta situación, se ha llevado a cabo una descripción a nivel histológico de la expresión del…
Ankk1 Loss of Function Disrupts Dopaminergic Pathways in Zebrafish
2022
Ankyrin repeat and kinase domain containing 1 (ANKK1) is a member of the receptor-interacting protein serine/threonine kinase family, known to be involved in cell proliferation, differentiation and activation of transcription factors. Genetic variation within the ANKK1 locus is suggested to play a role in vulnerability to addictions. However, ANKK1 mechanism of action is still poorly understood. It has been suggested that ANKK1 may affect the development and/or functioning of dopaminergic pathways. To test this hypothesis, we generated a CRISPR-Cas9 loss of function ankk1 zebrafish line causing a 27 bp insertion that disrupts the ankk1 sequence introducing an early stop codon. We found that…
