Biology of advanced uveal melanoma and next steps for clinical therapeutics [PDF]

open access: yes, 2014
Uveal melanoma is the most common intraocular malignancy although it is a rare subset of all melanomas. Uveal melanoma has distinct biology relative to cutaneous melanoma, with widely divergent patient outcomes.

Rational design of an N-terminal cysteine-containing tetrapeptide that inhibits tyrosinase and evaluation of its mechanism of action

open access: yesCurrent Research in Food Science, 2023
There has been a resurgence of interest in bioactive peptides as therapeutic agents. This is particularly interesting for tyrosinase, which can be inhibited by thiol-containing peptides.

Tyrosinase Inhibitors from Crude Drugs.

open access: yesBiological and Pharmaceutical Bulletin, 1994
Various crude drugs were examined for their tyrosinase inhibitory activity. Marked activity was observed in Chouji and Yakuchi extracts and the active substances in these extracts were identified as eugenol and yakuchinone A, respectively. Other vanillyl compounds such as ferulic acid, curcumin and yakuchinone B also had higher activities than eugenol ...

Immunological backbone of uveal melanoma: is there a rationale for immunotherapy? [PDF]

open access: yes, 2019
No standard treatment has been established for metastatic uveal melanoma (mUM). Immunotherapy is commonly used for this disease even though UM has not been included in phase III clinical trials with checkpoint inhibitors.

A Competitive Inhibitor of Tyrosinase [PDF]

open access: yesAustralian Journal of Biological Sciences, 1951
The kinetics of the activation of catechol by tyrosinase prepared from the potato and the mushroom, and of its inhibition by sodium m-hydroxybenzoate, have been studied. The enzyme-substrate dissociation constants differed markedly between the two enzyme sources (K.

Novel tyrosinase inhibitory peptide with free radical scavenging ability

open access: yesJournal of Enzyme Inhibition and Medicinal Chemistry, 2019
Tyrosinase is a key enzyme involved in melanin synthesis. Therefore, various tyrosinase inhibitors have been screened by researchers in recent years. In the present study, we discovered a novel tyrosinase inhibitor, a peptide ECGYF (named EF-5), with ...

Loss of strumpellin in the melanocytic lineage impairs the WASH Complex but does not affect coat colour [PDF]

open access: yes, 2016
The five-subunit WASH complex generates actin networks that participate in endocytic trafficking, migration and invasion in various cell types. Loss of one of the two subunits WASH or strumpellin in mice is lethal, but little is known about their role in
