A novel gene-pair signature for relapse-free survival prediction in colon cancer
This study aims to investigate the antiproliferative activity and potential mechanism of action of the xanthoquinodin JBIR-99, isolated from fungi Parengyodontium album MEXU 30,054 and identified by single-crystal X-ray crystallography. Cytotoxicity of xanthoquinodin was evaluated in a panel of human cancer cells lines and CCD-112-CoN normal colon cells, using the sulforhodamine B assay. PC-3 prostate cancer cells were used in biochemical assays including cell cycle, mitochondrial transmembrane potential (MTP), reactive oxygen species (ROS) and caspase activity. Expression levels of apoptosis-pathway-related proteins were ...
Conclusions: The results suggest that these polymorphisms probably has not a substantial role in Iranian CRC risk and is not a serious potential factor in risk assessment of mentioned disease among Iranians. PMID: 31523666 [PubMed]
Programmed cell death 4 (PDCD4) is a tumor suppressor gene implicated in many cellular functions, including transcription, translation, apoptosis, and the modulation of different signal transduction pathways. The downstream mechanisms of PDCD4 have been well-discussed, but its upstream regulators have not been systematically summarized. Noncoding RNAs (ncRNAs) are gene transcripts with no protein-coding potential but play a pivotal role in the regulation of the pathogenesis of solid tumors, cardiac injury, and inflamed tissue. In recent studies, many ncRNAs, especially microRNAs (miRNAs) and long noncoding RNAs (lncRNAs), ...
In conclusion, xantoxyletin primarily show potential anticancer activity. The root bark of C. harmandiana is a good source of bioactive compounds or the lead for the development of new pharmaceutical agent.
ConclusionsAlcohol consumption was minimally associated with all-cancer risk. Cigarette smoking clearly increased all-cancer risk, with females being more affected than males. Combined use of alcohol and tobacco increased the risk of developing all, colon, and prostate cancers. A “U-shaped” multiplicative interaction was observed for breast cancer when alcohol and tobacco were used in combination.

ConclusionsPET/CT was useful for early detection of EPCs. The use of PET/CT for the early detection and treatment of EPCs with no symptoms can improve treatment outcomes.
Publication date: 16 September 2019Source: Cancer Cell, Volume 36, Issue 3Author(s): Jürgen RulandIn this issue of Cancer Cell, Jackstadt et al. report that pathological Notch signaling in colorectal cancer (CRC) cells can initiate a neutrophil-dependent, TGF-β-mediated cascade that leads to metastatic disease. Inhibition of this pathway with clinically relevant compounds blocks metastatic spread in a developed murine model of CRC.
Authors: Gu J, Wang L, Li T, Tang S, Wang Y, Zhang W, Jiang X Abstract Oxaliplatin (OXA) is routinely used as the first‑line treatment for colorectal cancer (CRC). The addition of OXA to chemotherapy has significantly improved the prognosis of patients with CRC; however, some cases are resistant to OXA. The present study explored the influence of organic cation transporter 3 (OCT3) expression on the effects of OXA on CRC cell viability, and investigated the direct effects of OCT3 on viability, invasion and migration of CRC cells using MTT assay, wound healing assay, reverse transcription‑quantitative polymerase...
In conclusion, resveratrol may suppress the invasion and metastasis of colon cancer through reversal of EMT via the AKT/GSK‑3β/Snail signaling pathway. AKT1 may therefore be a key regulator of EMT in colon cancer cells and a potential therapeutic target for this disease. PMID: 31524255 [PubMed - as supplied by publisher]
