In vitro and in vivo studies on the association of long non‑coding RNAs H19 and urothelial cancer associated 1 with the susceptibility to 5‑fluorouracil in rectal cancer. Int J Oncol. 2019 Oct 04;: Authors: Yokoyama Y, Sakatani T, Wada R, Ishino K, Kudo M, Koizumi M, Yamada T, Yoshida H, Naito Z Abstract There is no predictive biomarker for response to 5‑fluorouracil (5FU)‑based neoadjuvant chemotherapy (NAC) in rectal cancer. In the present study, we examined potential long non‑coding RNAs (lncRNAs) linked to the susceptibility to 5FU in cultured colorectal cancer cells, and in biopsy and resected tissues of 31 human rectal cancer cases treated with NAC. Candidate lncRNAs for the prediction of susceptibility to 5FU were investigated by comprehensive analysis of expression profiles of 84 lncRNAs in cultured cells using PCR array. Bioinformatic analysis identified H19 and urothelial cancer associated 1 (UCA1) as candidate biomarkers for 5FU susceptibility. Quantitative PCR of H19 and UCA1 in cultures of colorectal cancer cells demonstrated the notable variation in expression. The ratios of changes of H19 and UCA1 expression in response to 5FU were low in cells resistant to 5FU, whereas ratios were high in cells susceptible to 5FU. In 5FU‑susceptible cells, cell proliferation was inhibited by 5FU. Upregulation of H19 and UCA1 were associated with the reduction in target molecule expression, including retinoblastoma and p27kip1.

Publication date: Available online 11 December 2019Source: The Lancet Global HealthAuthor(s): Adam Wagstaff, Sven NeelsenSummaryBackgroundThe goal of universal health coverage (UHC) requires that everyone receive needed health services, and that families who get needed services do not suffer undue financial hardship. Tracking progress towards UHC requires measurement of both these dimensions, and a way of trading them off against one another.MethodsWe measured service coverage by a weighted geometric average of four prevention indicators (antenatal care, full immunisation, and screening for breast and cervical cancers) and...

os AC Abstract PURPOSE: To examine the effects of Arrabidaa chica (Bignoniacea) extract, a native plant of the Amazon known as crajiru, on a 7,12-dimethyl-1,2-benzanthracene (DMBA)-induced breast cancer model in Wistar rats. METHODS: We compared the response of breast cancer to the oral administration of A. chica extract (ACE) for 16 weeks, associated or not with vincristine. Groups: normal control; DMBA (50mg/kg v.o,) without treatment; DMBA+ACE (300 mg/kg); DMBA+vincristine. 500μg/kg injected i.p; DMBA+ACE+Vincristine 250μg/kg i.p. Imaging by microPET and fluorescence, biochemistry, oxidative stress, ...

al-Filho DC Abstract Carbohydrate antigen 125 (CA125) has long been used as an ovarian cancer biomarker. However, because it is not specific for ovarian cells, CA125 could also be used to monitor congestion and inflammation in heart disease. Acute heart failure (HF) is used to identify patients with a worse prognosis in ST-segment elevation myocardial infarction (STEMI). We aimed to determine the association of CA125 with acute HF in STEMI and to compare CA125 with N-terminal pro brain natriuretic peptide (NTproBNP) with a cross-sectional study. At admission, patients were examined to define Killip class and then ...

Abstract Polydatin (PD), a monocrystalline polyphenolic drug mainly found in the roots of Polygonum cuspidatum, has various pharmacological activities. Long non-coding RNAs (lncRNA) DiGeorge syndrome critical region gene 5 (DGCR5) was found to participate in the suppression of multiple cancers. Here, we proposed to study the effect of PD on myocardial infarction (MI) by inducing DGCR5. CCK-8 assay was performed to detect the viability of H9c2 cells. Flow cytometry was utilized to test apoptosis of H9c2 cells. These results determined the optimal concentration and effect time of hypoxia as well as PD. Si-DGCR5 was ...

This study contributes with the discussion about the development of the molecular profiling of prostate cancer. The further development of similar studies could help in stratifying specific risk groups, leading to a more personalized therapeutic decision for prostate cancer treatment.

Thorat, Rajeshkumar BalasubramanianAbstractWomen at high risk of developing breast cancer are a heterogeneous group of women including those with and without high-risk germline mutation/s. Prevention in these women requires a personalised and multidisciplinary approach. Preventive therapy with selective oestrogen receptor modulators (SERMs) like tamoxifen and aromatase inhibitors (AIs) substantially reduces breast cancer risk well beyond the active treatment period. The importance...
