Efecto terapéutico del compuesto BO-110 en un modelo animal de leiomioma

2023

Los miomas son los tumores benignos más frecuentes en las mujeres en edad reproductiva y pueden asociar numerosos síntomas como dolor, sangrado y problemas reproductivos. Sin embargo, actualmente no existe una terapia totalmente satisfactoria por lo que es de suma importancia la evaluación de nuevos tratamientos. En la búsqueda de opciones terapéuticas alternativas, hemos seleccionado el ácido poliinosina-policitidílico (pIC) conjugado con polietilenimina (PEI) [pICPEI], cuyo nombre comercial es BO-100. El compuesto pIC es un ARN sintético de doble cadena sin toxicidad asociada, que induce de manera selectiva la autofagia y apoptosis en un gran espectro de células tumorales. Presen…

Downregulation of thioredoxin-1-dependent CD95 S-nitrosation by Sorafenib reduces liver cancer

2020

Hepatocellular carcinoma (HCC) represents 80% of the primary hepatic neoplasms. It is the sixth most frequent neoplasm, the fourth cause of cancer-related death, and 7% of registered malignancies. Sorafenib is the first line molecular targeted therapy for patients in advanced stage of HCC. The present study shows that Sorafenib exerts free radical scavenging properties associated with the downregulation of nuclear factor E2-related factor 2 (Nrf2)-regulated thioredoxin 1 (Trx1) expression in liver cancer cells. The experimental downregulation and/or overexpression strategies showed that Trx1 induced activation of nitric oxide synthase (NOS) type 3 (NOS3) and S-nitrosation (SNO) of CD95 rece…

Pharmacological blockade of the fatty acid amide hydrolase (FAAH) alters neural proliferation, apoptosis and gliosis in the rat hippocampus, hypothal…

2015

Endocannabinoids participate in the control of neurogenesis, neural cell death and gliosis. The pharmacological effect of the fatty acid amide hydrolase (FAAH) inhibitor URB597, which limits the endocannabinoid degradation, was investigated in the present study. Cell proliferation (phospho-H3(+) or BrdU(+) cells) of the main adult neurogenic zones as well as apoptosis (cleaved caspase-3(+)), astroglia (GFAP(+)), and microglia (Iba1(+) cells) were analyzed in the hippocampus, hypothalamus and striatum of rats intraperitoneally treated with URB597 (0.3 mg/kg/day) at one dose/4-days resting or 5 doses (1 dose/day). Repeated URB597 treatment increased the plasma levels of the N-acylethanolamine…
