Melanoma stem cells promote metastasis via exosomal miR-1268a inactivation of autophagy

Biol. Res; 55 (), 2022
BACKGROUND: Metastatic melanoma has a high mortality rate and poor survival. This is associated with efficient metastatic colonization, but the underlying mechanisms remain elusive. Communication between cancer stem cells (CSCs) and cancer cells plays an important role in metastatic dissemination. Whethe...

NOP14 inhibits melanoma proliferation and metastasis by regulating Wnt/β-catenin signaling pathway

Braz. j. med. biol. res; 52 (1), 2019
Malignant melanoma is an aggressive skin cancer with a high mortality rate. Nucleolar protein 14 (NOP14) has been implicated in cancer development. However, the role of NOP14 in malignant melanoma progression remains largely unclear. In this study, we observed that malignant melanoma tissue showed NOP14 ...

Evaluation of nicotinamide as an anti-inflammatory and anti-angiogenic agent in uveal melanoma cell lines

Arq. bras. oftalmol; 80 (2), 2017
ABSTRACT Purpose: To investigate the effect of nicotinamide on the secretion of pro-an giogenic and pro-inflammatory cytokines in uveal melanoma cell lines. Methods: Two human uveal melanoma cell lines (92.1 and OCM-1) were treated with nicotinamide (10 mmol/L) or control media for 48 hours in culture....

Piceatannol induced apoptosis through up-regulation of microRNA-181a in melanoma cells

Biol. Res; 50 (), 2017
BACKGROUND: Melanoma took top position among the lethal cancers and, despite there have been some great attempts made to increase the natural life of patients with metastatic disease, long-lasting and complete remissions are few. Piceatannol, owns the similar function as resveratrol, has been defined as ...

Proton NMR characterization of intact primary and metastatic melanoma cells in 2D & 3D cultures

Biol. Res; 50 (), 2017
OBJECTIVE: To characterize the differences between the primary and metastatic melanoma cell lines grown in 2D cultures and 3D cultures. METHODS: Primary melanoma cells (WM115) and metastatic melanoma cells (WM266) extracted from a single donor was cultured in 2D as well as 3D cultures. These cells were c...

Evaluación de reactividad inmunohistoquímica con método del Complejo Avidina–Biotina (ABC)

Inmunohistoquímica es toda técnica que permite detectar in situ componentes celulares y extracelulares por medio de anticuerpos específicos, empleando sistemas de detección enzimáticos. Dentro de los métodos inmunohistoquímicos, la técnica del complejo avidina–biotina(ABC) es ampliamente utiliz...
