Rodent models of tumours of the central nervous system. [PDF]

Mol Oncol
We describe the evolution of experimental systems, illustrated here in a timeline to show changing popularity over time. Starting with chemical and viral carcinogenesis, systems then developed into increasingly sophisticated genetically modified animal models.

SEMA4D Knockdown Attenuates β‐Catenin‐Dependent Tumor Progression in Colorectal Cancer

BioMed Research International, Volume 2021, Issue 1, 2021., 2021
Semaphorin 4D (SEMA4D), a protein originally demonstrated to regulate the immune system and axonal growth cone collapse in the developing central nervous system, is overexpressed in various human malignancies, including colorectal cancer (CRC). This investigation was undertaken to examine the effects of SEMA4D silencing on the biological properties of ...

Roles of Bile‐Derived Exosomes in Hepatobiliary Disease

BioMed Research International, Volume 2021, Issue 1, 2021., 2021
Exosomes are vesicles with a diameter of 30‐150 nm produced by living cells and secreted into the extracellular matrix. Exosomes mediate cellular communication by carrying active molecules, such as nucleic acids, proteins, and liposomes. Although exosomes are found in various body fluids, little is known about bile‐derived exosomes.

A case of leucosis in Heptapterus mustelinus (Siluriformes, Heptapteridae) among populations of streams in southern Brazil. Has leucosis in Heptapterus mustelinus an adaptive value in shaded streams? [PDF]

Neotropical Biology and Conservation, 2023
Fish populations in environments with a high degree of geographic isolation may be prone to mutations expressed in the phenotypes. These mutations may be related to color pattern, forming leucistic individuals.

Association of LEI0258 Marker Alleles and Susceptibility to Virulent Newcastle Disease Virus Infection in Kuroiler, Sasso, and Local Tanzanian Chicken Embryos

Journal of Pathogens, Volume 2020, Issue 1, 2020., 2020
Newcastle disease (ND) control by vaccination and an institution of biosecurity measures is less feasible in backyard chicken in developing countries. Therefore, an alternative disease control strategy like the genetic selection of less susceptible chicken genotypes is a promising option. In the present study, genetic polymorphism of LEIO258 marker and
