Excited to finally share our latest study on #TranslocationRCC #PEComas @NatureComms! We generated the first ever, murine transgenic kidney tumor models of SFPQ-TFE3 - the most common MiT/TFE gene fusion implicated in both, tRCC and PEComas (Perivascular Epitheloid neoplasms). We describe a novel role for this fusion in regulating #mTORC1-driven lineage plasticity, with transcriptional downregulation of critical nephric lineage transcription factors like PAX8, that perfectly recapitulate human renal PEComas. Additionally, we nominate the lysosomal V-ATPase complex as a central regulator of mTORC1 activity in tRCC, and a target-rich environment for therapeutic intervention in this deadly disease. Grateful to all the co-authors, collaborators, reviewers, editors and funding sources who made this study possible! @adriannaamendes @LotanLab @eddieimada @MasayaBaba2 @terry_watnickmd @WMarstonLinehan @PeterArgani @yasserged @rmelias2 @nirmishsingla @allaf_mo @Joeyswings @KidneyCancer @kidneycan @CDMRP nature.com/articles/s41467-0…

WH spokesperson Andrew Bates responds to this hearing yesterday: "It’s unbelievable that this needs to be said: calls for genocide are monstrous and antithetical to everything we represent as a country."
The presidents of @Harvard, @MIT, and @Penn were all asked the following question under oath at today’s congressional hearing on antisemitism: Does calling for the genocide of Jews violate [your university’s] code of conduct or rules regarding bullying or harassment? The answers they gave reflect the profound moral bankruptcy of Presidents Gay, Magill and Kornbluth. Representative @EliseStefanik was so shocked with the answers that she asked each of them the same question over and over again, and they gave the same answers over and over again. In short, they said: It ‘depends on the context’ and ‘whether the speech turns into conduct,’ that is, actually killing Jews. This could be the most extraordinary testimony ever elicited in the Congress, certainly on the topic of genocide, which to remind us all is: “the deliberate killing of a large number of people from a particular nation or ethnic group with the aim of destroying that nation or group” The presidents’ answers reflect the profound educational, moral and ethical failures that pervade certain of our elite educational institutions due in large part to their failed leadership. Don’t take my word for it. You must watch the following three minutes. By the end, you will be where I am. They must all resign in disgrace. If a CEO of one of our companies gave a similar answer, he or she would be toast within the hour. Why has antisemitism exploded on campus and around the world? Because of leaders like Presidents Gay, Magill and Kornbluth who believe genocide depends on the context. To think that these are the leaders of Ivy League institutions that are charged with the responsibility to educate our best and brightest. On the bright side, our congressional leaders deserve accolades for showing tremendous leadership and moral clarity in their statements, by the questions they asked, and the respectfulness with which they conducted the hearing. It was a masterclass of how our government and democracy should operate. If you have time, please watch the entire hearing. Throughout the hearing, the three behaved like hostile witnesses, exhibiting a profound disdain for the Congress with their smiles and smirks, and their outright refusal to answer basic questions with a yes or no answer.
