When BAP1 is lost, tumours become more aggressive, grow faster, and suppress the immune cells that would otherwise attack them. BAP1 loss is the most important molecular event in uveal melanoma progression, and it also plays a role in mesothelioma, renal cell carcinoma, and other cancers. However, scientists have been unable to study the consequences of BAP1 loss properly in the laboratory, because no suitable immune-competent model existed.\u00a0<\/p>\n<p>To address the issue, the research team used CRISPR-Cas9 gene editing to delete BAP1 from normal melanocyte cells, creating a new pre-clinical tumour model that behaves like human BAP1-deficient melanoma in an animal with a fully functioning immune system.\u00a0<\/p>\n<p>\u201cBAP1 loss is associated with poor prognosis and resistance to immunotherapy in melanoma. Until now, there has been no preclinical model that faithfully reproduces the tumour\u2013immune interactions seen in patients. Our model fills this gap, for the first time, by recapitulating the human tumour immune microenvironment in vivo. This provides a powerful platform to study how BAP1 loss drives immune evasion and to test novel immunotherapy combinations that may overcome treatment resistance,\u201d explains lead researcher of the study, Dr Mona Wang Meng from the University of Turku.\u00a0<\/p>\n<p>The absence of a proper laboratory model has been one of the biggest bottlenecks slowing down drug development for BAP1-deficient melanoma and related rare tumours. Previous models either lacked a functional immune system, making them useless for immunotherapy studies, or carry too many confounding mutations that obscure the specific role of BAP1.\u00a0<\/p>\n<p>\u201cThe implications go well beyond melanoma. BAP1 loss is a shared vulnerability across several hard-to-treat cancers. This platform allows us, and research groups worldwide, to rationally design and test new immunotherapy combinations \u2014 something that simply was not possible before,\u201d says Dr Carlos R. Figueiredo, the Principal Investigator of the study.\u00a0<\/p>\n<p>The study is part of the broader research programme of MIORG within the InFLAMES Research Flagship at the University of Turku, which focuses on harnessing the immune system to fight cancer.\u00a0<\/p>\n<p><strong>Source:<\/strong> University of Turku\u00a0<\/p>\n<\/div>\n<p><br \/>\n<br \/><a href=\"https:\/\/healthcare-in-europe.com\/en\/news\/laboratory-tool-bap1-melanoma.html\" target=\"_blank\" rel=\"noopener\">Source link <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>This provides a powerful platform to study how BAP1 loss drives immune evasion and to test novel immunotherapy combinations that may overcome treatment resistance Mona Wang Meng The key driver&hellip;<\/p>\n","protected":false},"author":1,"featured_media":188253,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_jetpack_newsletter_access":"","_jetpack_dont_email_post_to_subs":false,"_jetpack_newsletter_tier_id":0,"_jetpack_memberships_contains_paywalled_content":false,"_jetpack_feature_clip_id":0,"_jetpack_memberships_contains_paid_content":false,"footnotes":"","jetpack_publicize_message":"","jetpack_publicize_feature_enabled":true,"jetpack_social_post_already_shared":true,"jetpack_social_options":{"image_generator_settings":{"template":"highway","default_image_id":0,"font":"","enabled":false},"version":2},"jetpack_post_was_ever_published":false},"categories":[7],"tags":[],"class_list":["post-188252","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-national-news"],"jetpack_publicize_connections":[],"jetpack_featured_media_url":"https:\/\/newslink360.space\/wp-content\/uploads\/2026\/07\/rect-01-turku-laboratory.jpg","jetpack_likes_enabled":true,"jetpack-related-posts":[{"id":185518,"url":"https:\/\/newslink360.space\/?p=185518","url_meta":{"origin":188252,"position":0},"title":"Hidradenitis Suppurativa and ICIs &#8211; AMJ","author":"Ajay Kumar Verma","date":"June 25, 2026","format":false,"excerpt":"HIDRADENITIS suppurativa may newly develop or flare in some patients receiving immune checkpoint inhibitor therapy.
