UCLA Health System's Gastroenterology and GI Surgery Specialties Ranked No. 5 in the Nation in U.S. News' Annual Survey
Once again, the UCLA Health System's hospitals in Westwood and Santa Monica have been named to U.S. News and World Report's Best Hospitals 2014-15 Honor Roll. UCLA was ranked No. 5 in the country and No. 1 in both California and the Los Angeles metropolitan area. The annual rankings, now in their 25th year, are the magazine's most exclusive rankings, recognizing hospitals that excel at treating patients who need an especially high level of care. This year's Honor Roll highlights just 17 hospitals out of nearly 5,000 nationwide for their expertise in treating the most challenging patients across a range of medical specialties.

Nine UCLA Digestive Disease Physicians Voted Best Doctors in America for 2014
Best Doctors conducts an exhaustive, peer-reviewed survey of the medical profession, polling more than 50,000 doctors across the country. Doctors are asked to provide an assessment of the clinical abilities of their peers within each of the more than 400 subspecialties of medicine. The millions of individual data points collected through this process, after being compiled through algorithms that correct for statistical bias, yields the list of those physicians deemed "best" by their peers. Continuous peer-to-peer surveys help identify specialists who are considered by fellow physicians to be the most skilled in their fields and most qualified for reviewing and treating complex medical conditions.
Best Doctors objective is to identify the best trained, most experienced and most skilled specialists, regardless of where they practice. Only 5% of the doctors in any country are actually selected to become Best Doctors.
Best Doctors has earned a worldwide reputation for reliable, impartial results by remaining totally independent. Doctors are not paid to complete the survey, and cannot pay to be included in the database.

Ivy Ka Man Law, PhD - Recipient of the 2014 GRG/AGA Abstract of the Year Award
Dr. Law received her PhD and MPhil degrees in Department of Pharmacology and Pharmacy and Department of Zoology of the University of Hong Kong respectively. Her MPhil thesis is on the development of mucosal immunity against Severe Acute Respiratory Syndrome (SARS) virus induced by recombinant adenovirus. During her PhD studies, her major focus is on the role of lipocalins in the development of insulin resistance. The other project involved the identification of possible interacting partners of Sirtuin 1 and 3, which play important roles in aging and metabolism.
The post-doctoral research of Dr. Law focuses on neurotensin receptor signaling and neurotensin-induced pro-inflammatory responses in colonocytes. Currently, she is working on a project investigating the role of neurotensin receptor internalization and recycling on the induction of pro-inflammatory responses in colonocytes and the possible mechanisms regulating colonocyte desensitization and re-sensitization.

Background and Aims: MicroRNAs (miRNAs) are short non-coding RNAs involved in different pathophysiological functions at the post-transcriptional level. Neurotensin (NTS)/neurotensin receptor 1 (NTSR1) interactions mediate intestinal inflammation and proliferation in vitro and in vivo. We have recently shown that NTS exposure to NTSR1-expressing human colonic NCM460 epithelial cells (NCM460-NTSR1) induces differential expression of miRNAs (Gastroenterology 2011;141:1749) and NTS-modulated miR-133α expression regulates the expression of its downstream target aftiphilin (AFPTH) (DDW2013: #934). Here we elucidated the mechanism by which miR-133α regulates NTS signaling in vitro, and studied the functional consequences of this response in colitis. Methods: NTS/miR-133α -regulated proinflammatory cytokine production in NCM460-NTSR1 cells and colon tissues was examined by qPCR and Bio-Plex Pro Human Cytokine Assay. Acute colonic inflammation was induced by intracolonic administration of TNBS (5 mg/kg, 48 h). Expression of miR-133α in the colon was inhibited by intracolonic administration of anti-sense (as)-miR-133α (2 doses, every two days) before TNBS treatment. The degree of inflammation was evaluated on distal colon segments stained with H&E. Results: MiR-133α overexpression in NCM460-NTSR1 cells increased transcription of IL-8, IL-1β and TNF-α, while its knock-down attenuated NTS-induced IL-8 and IL-6 transcription (P<0.01). Bio-plex cytokine assays showed that NTS/miR-133α/AFTPH interactions are directly involved in the production of IL-1β (P<0.05). MiR-133α knock-down in mouse colon reduced colonic cxcl1, lcn2 and TNF-α expression (P<0.05) and neutrophil infiltration (P<0.05) in response to intracolonic TNBS administration. MiR-133α levels we increased (15-times, p<0.0001) during TNBS-induced colitis. MiR-133α knock-down in vivo also improved mucosal integrity (P<0.05) and overall histological score (P<0.05), supported by increased expression of the colonic epithelial cell marker, krt20 (P<0.01). Importantly, AFTPH transcription levels were significantly lower (P=0.0104) while miR-133α levels were up-regulated in colon tissues from patients with ulcerative colitis (n=22), compared to control tissues (n-21). Conclusions: miR-133α/AFTPH interactions regulate NTS-stimulated proinflammatory response in human colonic epithelial cells. Silencing of miR-133α in the colon reduces cytokine expression and histologic damage and inflammation in mouse colitis. These results suggest that miR-133α/AFTPH interactions promote NTS-induced proinflammatory responses in the colonic mucosa. Targeting of miR-133α in the colon may represent a novel form for treatment in Inflammatory Bowel Disease.
