    摘要: This process, which essentially comprises the following steps:esterification of the free acid groups of the collagen,transformation of the esterified groups into hydrazides groups,transformation of the hydrazide groups into azide groups by the action of nitrous acid, is characterized in that each step is separated by a rinsing in an aqueous salt solution, and in that the step of transformation of esterified groups into azide groups and the step of transformation of hydrazide groups into azide groups by the action of nitrous acid, are performed in the presence of salt.

    摘要: Methods and pharmaceutical compositions for the treatment of BAP1 deficient cancer are based on investigation of the role of BET (Bromodomain and Extra-Terminal motif proteins) in BAP1 deficient cancer and screened isogenic cells (BAP1 WT vs KO). BET inhibitors show more anti-proliferative activity against cells KO for BAP1. Using isogenic cell lines and uveal melanoma PDX derived cell lines with different status of expression for BAP1 showed a highest dose response to a BET inhibitors (OTX015 and BI894999) in BAP1 KO isogenic cells compared to WT cells and an enhanced dose response to OTX015 in a BAP1 mutated uveal melanoma (UM) derived cells compared to UM cells expressing BAP1. BET inhibitors have a role in BAP1 deficient cancer, and BET inhibitors are useful in the treatment of BAP1 deficient cancer, particularly BAP1 deficient Uveal Melanoma, clear cell Renal Carcinoma, cholangiocarcinoma and mesothelioma.
