Peptide L13S Derived from the BRN2 POU Domain Reduces Metastasis and Inhibits Cell Migration and Invasion .

Background/aim: The Brain-Specific Homeobox/POU Domain Protein 2 (BRN2) transcription factor supports melanoma progression by regulating the expression of several genes involved in cell migration and invasion. We hypothesized that a peptide designed based on the POU domain of BRN2 could block the BRN2 transcription activity and, consequently, reduce metastasis.

Materials And Methods: Cell viability was accessed by Trypan Blue exclusion dye assay and xCelligence platform.

Astaxanthin induces autophagy and apoptosis in murine melanoma B16F10-Nex2 cells and exhibits antitumor activity .

Countless efforts have been made to prevent and suppress the formation and spread of melanoma. Natural astaxanthin (AST; extracted from the alga ) showed an antitumor effect on various cancer cell lines due to its interaction with the cell membrane. This study aimed to characterize the antitumor effect of AST against B16F10-Nex2 murine melanoma cells using cell viability assay and evaluate its mechanism of action using electron microscopy, western blotting analysis, terminal deoxynucleotidyl transferase dUTP nick-end labelling (TUNEL) assay, and mitochondrial membrane potential determination.

In Vitro and In Vivo Inhibitory Activity of Limonene against Different Isolates of spp.

Commensal yeast from the genus is part of the healthy human microbiota. In some cases, spp. dysbiosis can result in candidiasis, the symptoms of which may vary from mild localized rashes to severe disseminated infections.

Peptide R18H from BRN2 Transcription Factor POU Domain Displays Antitumor Activity In Vitro and In Vivo and Induces Apoptosis in B16F10-Nex2 Cells.

Background: BRN2 transcription factor is associated with the development of malignant melanoma. The cytotoxic activities and cell death mechanism against B16F10-Nex2 cells were determined with synthetic peptide R18H derived from the POU domain of the BRN2 transcription factor.

Objective: To determine the cell death mechanisms and in vivo activity of peptide R18H derived from the POU domain of the BRN2 transcription factor against B16F10-Nex2 cells.

Cyclopalladated Compound 7a Induces Apoptosis- and Autophagy-Like Mechanisms in Paracoccidioides and Is a Candidate for Paracoccidioidomycosis Treatment.

Paracoccidioidomycosis (PCM), caused by Paracoccidioides species, is the main cause of death due to systemic mycoses in Brazil and other Latin American countries. Therapeutic options for PCM and other systemic mycoses are limited and time-consuming, and there are high rates of noncompliance, relapses, toxic side effects, and sequelae. Previous work has shown that the cyclopalladated 7a compound is effective in treating several kinds of cancer and parasitic Chagas disease without significant toxicity in animals.
