Pancreatic ductal adenocarcinoma (PDA) harbors an exceedingly poor prognosis, and is generally considered a therapy-recalcitrant disease due to poor response to conventional chemotherapy coupled with non-actionable genetic drivers (e.g. KRAS mutations). However, PDA frequently loses p16ink4a, thereby leading to deregulation of CDK4/6. Surprisingly, in established cell models and xenografts, CDK4/6 inhibition has a modest effect on proliferation and resistance develops rapidly. To determine if such weak response was an intrinsic feature of PDA, we developed primary tumor explants that maintain the tumor environment and recapitulate feuture of primary PDA. The CDK4/6 inhibitor PD-0332991 was highly efficient at suppressing proliferation in …

Background
Polybromo-1 (PBRM1), a targeting subunit of the SWI/SNF chromatin remodeling complex, is mutated at a rate of ~40% in clear cell Renal Cell Carcinoma (ccRCC), second only to VHL. Whether its mutation is correlated with tumor stage is controversial. As other components of the SWI/SNF complex were also reported to be mutated in ccRCC, we aim to examine the protein expression patterns of PBRM1, ARID1A, BRG1, and BRM in ccRCC, and to investigate possible association between their loss of expression and tumor stage, as well as survival. We also included a histone modifier, SETD2, which is recently discovered to …

Background
Chordoma is a rare but locally aggressive malignant neoplasm showing notochordal differentiation. The clinical differential diagnoses can be extensive, and definitive diagnosis often relies on histopathologic evaluation. Histologically, chordoma shows dual epithelial and mesenchymal differentiation, with various morphologies. Despite surgical resection and use of adjuvant radiation therapy, the local recurrence rate of chordoma remains high. We aim to establish factors associated with the increased risk of recurrence and help guide treatment decisions.
