BC200 is a long non-coding RNA (lncRNA) that has been implicated in the regulation of protein synthesis, yet whether dysregulation of BC200 contributes to the pathogenesis of human diseases remains elusive. In this study, we show that BC200 is upregulated in breast cancer; among breast tumor specimens there is a higher level of BC200 in estrogen receptor (ER) positive than in ER-negative tumors. Further experiments show that activation of estrogen signaling induces expression of BC200. To determine the significance of ER-regulated BC200 expression, we knockout (KO) BC200 by CRISPR/Cas9. BC200 KO suppresses tumor cell growth in vitro and in vivo by expression of the pro-apoptotic Bcl-xS isoform. Mechanistically, BC200 contains a 17-nucleotide sequence complementary to Bcl-x pre-mRNA, which may facilitate its binding to Bcl-x pre-mRNA and recruitment of heterogeneous nuclear ribonucleoprotein (hnRNP) A2/B1, a known splicing factor. Consequently, hnRNP A2/B1 interferes with association of Bcl-x pre-mRNA with the Bcl-xS-promoting factor Sam68, leading to a blockade of Bcl-xS expression. Together, these results suggest that BC200 plays an oncogenic role in breast cancer. Thus, BC200 may serve as a prognostic marker and possible target for attenuating deregulated cell proliferation in estrogen-dependent breast cancer.

Introduction These Asian Working Group guidelines on diet in inflammatory bowel disease (IBD) present a multidisciplinary focus on clinical nutrition in IBD in Asian countries. Methodology The guidelines are based on evidence from existing published literature; however, if objective data were lacking or inconclusive, expert opinion was considered. The conclusions and 38 recommendations have been subject to full peer review and a Delphi process in which uniformly positive responses (agree or strongly agree) were required. Results Diet has an important role in IBD pathogenesis, and an increase in the incidence of IBD in Asian countries has paralleled changes in the dietary patterns. The present consensus endeavors to address the following topics in relation to IBD: (i) role of diet in the pathogenesis; (ii) diet as a therapy; (iii) malnutrition and nutritional assessment of the patients; (iv) dietary recommendations; (v) nutritional rehabilitation; and (vi) nutrition in special situations like surgery, pregnancy, and lactation. Conclusions Available objective data to guide nutritional support and primary nutritional therapy in IBD are presented as 38 recommendations.

Background:Achalasia is a chronic disease that can be managed with effective endoscopic modalities.Aim:To evaluate the effectiveness of single setting of pneumatic balloon dilatation for achalasia and assess the long-term success and outcomes.Materials and methods:This is a retrospective study of all achalasia patients who underwent pneumatic balloon dilatation at our institute. Patients who could be contacted were inquired regarding their symptoms and dysphagia-free interval after dilatation.Results:A total of 72 patients were enrolled. Out of this, 14 patients lost to follow-up. Mean age of 58 patients was 45.02 ± 16.51 years. Male:female ratio was 13:16. Mean predilatation Eckardt score was 7.16 ± 0.834. Type I achalasia was present in 10 (17.2%), type II in 44 (75.9%), type III in 4 (6.9%). Predilatation basal integrated relaxation pressure (IRP) was 28.14 ± 14.76 mm Hg. Postdilatation Eckardt score was 2.40 ± 1.67. Postdilatation dysphagia-free interval was 17.28 ± 6.70 months. A total of 9 patients (15.51%) failed to respond to first dilatation and 49 (84.48%) patients benefited from single setting of pneumatic dilatation. Esophageal perforation occurred in 2/58 (3.44%). We did not find any significant difference in gender distribution, age of presentation, duration of symptom, pre- and postdilatation Eckardt score, type of achalasia, and basal IRP on manometry between type of achalasia. Postdilatation dysphagia-free interval in type II achalasia (18.09 ± 5.976 months) was more than types I and III achalasia cardia (p = 0.066), which showed trend toward significance.Conclusion:Pneumatic balloon dilatation of achalasia cardia is a highly effective endoscopic procedure with minimal complications and mortality. Even the single setting of dilatation can have long-lasting dysphagia-free interval.How to cite this article: Gupta SJ, Gaikwad NR, Samarth AR, Gattewar SR.
