Peptide delays melanoma growth in animal trials
Publicado em 20 maio 2022
An article published in Scientific Reports describes a study demonstrating the effectiveness of a peptide developed by Brazilian scientists, called Rb4, in combating cancer progression in an animal model, especially malignant melanoma. The molecule holds promise for the treatment of drug-resistant tumors.
Preclinical in vitro and in vivo trials indicated that Rb4 triggers necrosis in murine melanoma cells, and inhibits the viability of human cancer cells. Tumor [...]

Researchers confirm a new way to develop drugs to treat multiple sclerosis, asthma
Publicado em 10 março 2021Brazilian researchers studying local poisonous fish have confirmed the path to developing drugs to treat chronic inflammatory diseases such as multiple sclerosis and asthma. The venomous toad Thalassophryne nattereri contains a peptide (TnP) that has anti-inflammatory and anti-allergic potential. Currently, confirmation of this potential has occurred with the zebrafish Danio rerio, a popular aquarium species native to South Asia that shares 70% of its genome with humans and is widely used as a [...]ver notícia -
Researchers confirm new drug development route for treating multiple sclerosis, asthma
Publicado em 10 março 2021Brazilian researchers who study a native venomous fish have confirmed a route to drug development for the treatment of chronic inflammatory diseases such as multiple sclerosis and asthma. The venomous toadfish Thalassophryne nattereri contains a peptide (TnP) with anti-inflammatory and anti-allergic potential. Confirmation of this potential has now come via the zebrafish Danio rerio, a popular aquarium species native to South Asia that shares 70% of its genome with humans and is widely used as [...]ver notícia -
Two novel viruses identified in Brazilian patients with suspected dengue
Publicado em 17 abril 2020Two new species of viruses have been identified in blood samples taken from patients in Brazil’s northern region who had similar symptoms to those of dengue or Zika, such as high fever, severe headache, rash and red skin spots. One belongs to the genus Ambidensovirus and was found in a sample collected in the state of Amapá. The other belongs to the genus Chapparvovirus and was found in blood from the state of Tocantins. The study was supported by São Paulo Research [...]ver notícia
