Suppressing NRIP1 inhibits growth of breast cancer cells in vitro and in vivo.

Earlier age at menarche is a major risk factor for breast cancer. Our previous study identified Nrip1 (also known as Rip140) as a candidate gene for delaying female sexual maturation (FSM) and found that knocking out Nrip1 could significantly delay FSM in mice. To investigate the effects of NRIP1 in breast cancer we used human cell lines and tissue arrays along with an in vivo study of DMBA-induced carcinogenesis in Nrip1 knockout mice.

Two Unexpected Tumors in a Laparoscopic Nephrectomy Specimen, Including a Rare Tubulocystic Renal-Cell Carcinoma: A Case Report.

We present a case of a 52-year-old Caucasian male who underwent a laparoscopic nephrectomy for an atrophic kidney and was found to have two unexpected, synchronous kidney cancers. He had a remote history of testicular cancer complicated by lymphadenopathy and external ureteral compression. Over time, he developed an atrophic left kidney from obstructive uropathy.

Cytologic features and diagnostic pitfalls of primary ampullary tumors by endoscopic ultrasound-guided fine-needle aspiration biopsy.

Background: Endoscopic ultrasound-guided fine-needle aspiration biopsy (EUS-guided FNAB) is highly sensitive and specific in cytologic diagnosis and clinical staging of malignant neoplasms of the gastrointestinal tract, pancreas, liver, and lymph nodes. However, no study has been performed to evaluate its accuracy, sensitivity, specificity, and the cytomorphologic features of suspected primary ampullary tumors.

Methods: All EUS-guided FNABs of suspected primary ampullary lesions at the University of California Irvine Medical Center (Orange, CA) from January 1998 to September 2004 were retrospectively retrieved.
