Effects of intragastrically-administered Tepary bean lectins on digestive and immune organs: Preclinical evaluation

Publication date: 2018Source: Toxicology Reports, Volume 5Author(s): Julia María Alatorre-Cruz, Wendoline Pita-López, Rosa Guadalupe López-Reyes, Roberto Augusto Ferriz-Martínez, Ricardo Cervantes-Jiménez, María de Jesús Guerrero Carrillo, Paola Jazmín Aranda Vargas, Gabriela López-Herrera, Adriana Jheny Rodríguez-Méndez, Aarón Zamora-Arroyo, Héctor Gutiérrez-Sánchez, Tércia Reis de Souza, Alejandro Blanco-Labra, Teresa García-GascaAbstractPrevious work showed that Tepary bean (Phaseolus acutifolius) lectins exhibit differential cytotoxic effects on cancer cell lines by apoptosis induction. In vivo studies using a Tepary bean lectin fraction (TBLF, 50 mg/kg of body weight) after colon cancer induction in rats showed that TBLF inhibited early precancerous lesions without systemic toxicity however, loss of body weight gain and activation of immune cells were observed. In order to know more about the possible adverse effects, we evaluated the administration of TBLF on digestive and immune organs. Sprague Dawley rats were administered TBLF for six weeks and allowed to recover for two weeks. Immune activation was observed through an increased lymphocyte-granulocyte ratio, an increased number of lymphoid follicles in intestinal Peyer’s patches and a slight expansion of the splenic white pulp. Atrophy was observed in small intestine villi and crypt foci of t...

ConclusionThe most common cancers were those associated with 'westernisation' of lifestyle. Our figures contrast with other Sub-Saharan Africa countries where infection related cancers are most predominant. The MNCR has also improved its data quality over time.

ow JH Abstract Dual oxidase 2 (DUOX2) generates H2O2 that plays a critical role in both host defense and chronic inflammation. Previously, we demonstrated that the proinflammatory mediators IFN-γ and LPS enhance expression of DUOX2 and its maturation factor DUOXA2 through STAT1- and NF-κB‒mediated signaling in human pancreatic cancer cells. Using a panel of colon and pancreatic cancer cell lines, we now report the induction of DUOX2/DUOXA2 mRNA and protein expression by the TH2 cytokine IL-4. IL-4 activated STAT6 signaling that, when silenced, significantly decreased induction of DUOX2. Furthermore, ...

CONCLUSIONS: Adequate and improved pain control in patients with cancer, even in advanced stages, with concurrent quality of life maintenance is attainable. Results from this large-scale, multicenter, single-group cohort supplement existing RCT data that support IDDS as a safe and effective therapeutic option with a positive benefit-risk ratio in the treatment of cancer pain.

Mutations in tumor protein p53 are expressed in a variety of human cancers such as colon, pancreatic, breast, and non-small cell lung cancer. P53 acts as a tumor suppressor by regulating cell division and DNA repair. Mutations of p53 reduce or eliminate its regulatory functions, contributing to cancer formation and progression. Novel therapeutics are needed that specifically target p53 mutations, as small molecule inhibitors lack sequence specificity.T cell receptors (TCRs) are proteins expressed on the surface of T lymphocytes that can recognize peptide antigens from infected and malignant cells in the context of human le...

r M Abstract Neuroendocrine tumors (NETs) show low but increasing incidence and originate in multiple organs, including the pancreas, midgut, caecum, rectum, appendix, colon, and lungs. Due to their stunning genetic, histological, and clinical variability, diagnosis and treatment of NETs are challenging. In addition, low incidence and high variability hamper the implementation of high evidence trials. Therefore, guidelines do not cover the complexity of NETs and, frequently, treatment decisions are taken by interdisciplinary tumor conferences at comprehensive cancer centers. Treatment aims are (i) control of tumor...

Authors: Mendoza-Almanza G, Ortíz-Sánchez E, Rocha-Zavaleta L, Rivas-Santiago C, Esparza-Ibarra E, Olmos J Abstract Cervical cancer (CC) is one of the leading causes of cancer-associated mortalities in women from developing countries. Similar to other types of cancer, CC is considered to be a multifactorial disease, involving socioeconomic, cultural, immunological and epigenetic factors, as well as persistent human papilloma virus (HPV) infection. It has been well established that cancer stem cells (CSCs) play an important role in defining tumor size, the speed of development and the level of regressi...
