How inflammatory stimuli signal to the nucleus to restrict inflammation is poorly understood. Protein inhibitor of activated STAT1 (PIAS1), a transcriptional regulator that possesses small ubiquitin-related modifier (SUMO) E3 ligase activity, inhibits immune responses by selectively blocking the binding of NF-kappaB and STAT1 to gene promoters. We report(More)
Primary biliary cirrhosis (PBC) is a chronic autoimmune liver disease of unknown etiology characterized by high-titer anti-mitochondrial antibodies. The major autoantigen has been identified as the E2 subunit of the pyruvate dehydrogenase complex (PDC-E2). The fact that PDC-E2 is present in all nucleated cells, but autoimmune damage is confined to biliary(More)
Purpose To identify quantitative imaging biomarkers at fluorine 18 ((18)F) positron emission tomography (PET) for predicting distant metastasis in patients with early-stage non-small cell lung cancer (NSCLC). Materials and Methods In this institutional review board-approved HIPAA-compliant retrospective study, the pretreatment (18)F fluorodeoxyglucose PET(More)
The most common chromosomal translocation in acute promyelocytic leukemia (APL), t15;17(q22;q21), creates PMLRARalpha and RARalphaPML fusion genes. We previously developed a mouse model of APL by expressing PMLRARalpha in murine myeloid cells. In order to examine the mechanisms by which PMLRARalpha can initiate leukemia, we have now generated transgenic(More)
We utilized a mouse model of acute promyelocytic leukemia (APL) to investigate how aberrant activation of cytokine signaling pathways interacts with chimeric transcription factors to generate acute myeloid leukemia. Expression in mice of the APL-associated fusion, PML-RARA, initially has only modest effects on myelopoiesis. Whereas treatment of control(More)
PURPOSE To identify clinical and dosimetric factors associated with vagus nerve (VN) and recurrent laryngeal nerve (RecLN) injury following stereotactic ablative radiation therapy (SABR) in the chest. METHODS AND MATERIALS We examined the clinical courses and SABR plans of 67 patients treated for T1 or T2 non-small cell lung cancer of the upper right or(More)
The promyelocytic leukemia retinoic acid receptor alpha (PMLRARalpha) chimeric protein is associated with acute promyelocytic leukemia (APL). PMLRARalpha transgenic mice develop leukemia only after several months, suggesting that PMLRARalpha does not by itself confer a fully malignant phenotype. Suppression of apoptosis can have a central role in(More)
An increasing body of experience suggests that oligometastasis represents a minimal metastatic state with the potential for cure or prolonged survival in selected patients treated with radical local therapy to all identified sites of disease. The main clinical scenarios managed by thoracic oncology specialists are pulmonary oligometastases from primary(More)
PURPOSE Stereotactic ablative radiation therapy (SABR) is increasingly used to treat lung oligometastases. We set out to determine the safety and efficacy of this approach and to identify factors associated with outcomes. METHODS AND MATERIALS We conducted a retrospective study of patients treated with SABR for metastatic lung tumors at our institution(More)
OBJECTIVES/HYPOTHESIS Postoperative radiation therapy is often used in patients with high-risk salivary gland carcinomas. In this study we evaluated the outcomes and prognostic factors in patients with minor salivary gland cancers treated with adjuvant radiation therapy. STUDY DESIGN Retrospective cohort study. METHODS We performed a retrospective(More)
