Fascioliasis is an infectious parasitic disease distributed globally and caused by the liver fluke Fasciola hepatica or F. gigantica. This neglected tropical disease affects both animals and humans, and it represents a latent public health problem due to the significant economic losses related to its effects on animal husbandry. For decades, triclabendazole has been the unique anti-Fasciola drug that can effectively treat this disease. However, triclabendazole resistance in fascioliasis has more recently been reported around the world, and thus, the discovery of novel drugs is an urgent need. The aim of this study was to investigate the fasciocidal properties of 400 compounds contained in the Pathogen Box. The first stage of the screening was carried out by measuring the fasciocidal activity on metacercariae at a concentration of 33 M each compound (the standard dose). Subsequently, the ...

Introduction: Hepatocellular carcinoma (HCC) is the third most frequent cancer of digestive tract tumors in Peru, with a high mortality rate of 17.7 per 100,000 inhabitants. A significant number of HCC cases in Peru do not follow the classic clinical epidemiology of the disease described in other parts of the world. Those patients present with a distinct transcriptome profile and a singular tumor process, suggesting a particular type of hepatocarcinogenesis in a portion of the Peruvian population. Aim: Our aim was to understand the clinical and biologic involvement of the epigenetic profile (methylation) and gene expression (transcriptome) of HCC in Peruvian patients. Methods: HCC and liver transcriptome and DNA methylation profiles were evaluated in 74 Peruvian patients. Results: When grouped by age, there was greater DNA methylation in younger patients with HCC but no differences with ...

En Perú, el carcinoma hepatocelular (CHC) ocupa el tercer lugar en incidencia entre los tumores del sistema digestivo, y tiene una alta tasa de mortalidad, 17.7 por 100,000 habitantes. La mayoría de los casos reportados no presentan la epidemiología clínica clásica del CHC observado en otras partes del mundo. Además, se ha identificado que estos pacientes presentan un perfil transcriptómico distinto y un proceso tumoral singular, sugiriendo un proceso particular de hepatocarcinogénesis en una fracción de la población peruana. El presente estudio busca comprender la implicancia clínica y biológica del perfil epigenético (metilación) y de expresión de los genes (transcriptómico) del CHC en los pacientes peruanos. Se evaluó el perfil de transcriptómico y de metilación de ADN de hígado y CHC en 74 pacientes peruanos. El agrupamiento por edades mostró una mayor metilació...
