Epithelial mesenchymal transition and resistance in endocrine-related cancers
Publication date: Available online 18 May 2019Source: Biochimica et Biophysica Acta (BBA) - Molecular Cell ResearchAuthor(s): Zoran CuligAbstractEpithelial to mesencyhmal transition (EMT) has a central role in tumor metastasis and progression. EMT is regulated by several growth factors and pro-inflammatory cytokines. The most important role in this regulation could be attributed to transforming growth factor-β (TGF-β). In breast cancer, TGF-β effect on EMT could be potentiated by Fos-related antigen, oncogene HER2, epidermal growth factor, or mitogen-activated protein kinase kinase 5 – extracellular-regulated kinase signaling. Several microRNAs in breast cancer have a considerable role either in potentiation or in suppression of EMT thus acting as oncogenic or tumor suppressive modulators. At present, possibilites to target EMT are discussed but the results of clinical translation are still limited. In prostate cancer, many cellular events are regulated by androgenic hormones. Different experimental results on androgenic stimulation or inhibition of EMT have been reported in the literature. Thus, a possibility that androgen ablation therapy leads to EMT thus facilitating tumor progression has to be discussed. Novel therapy agents, such as the anti-diabetic drug metformin or selective estrogen receptor modulator ormeloxifene were used in pre-clinical studies to inhibit EMT in prostate cancer. Taken together, the results of pre-clinical and clinical studies...

AbstractA novel series of coumarin-pyridine/fused pyridine hybrids were designed and synthesized. Their anticancer activity was evaluated against human cancer cell lines MCF-7, HCT-116, HepG-2, and A549. Compounds9,10, and11 showed the most potent growth inhibitory activities with IC50 values ranging from 1.1 to 2.4 μM, against MCF-7 cell line. Flow cytometric analysis revealed that these compounds induced cell cycle arrest in the G2/M phase followed by apoptotic cell death. Consistent with these results, the activity of caspase-3 in MCF-7 cells was tested. The results indicated that compounds9,10, and11 increas...
(Medical College of Georgia at Augusta University) A checkpoint may delay travelers but it can help give cancer free rein by suppressing the natural immune response that should destroy it, researchers say.
(Oxford University Press USA) A new study soon to appear in the Faculty of Public Health's Journal of Public Health, published by Oxford University Press, suggests that air pollution and living in apartment buildings may be associated with an increased risk for dangerous conditions like heart disease, stroke, and type 2 diabetes. This paper is embargoed until midnight EST on June 25.
Contributors : Rui Kuang ; Wei ZhangSeries Type : OtherOrganism : Homo sapiensThe NanoString experiment were conducted on 59 cell lines including 12 ovary cell lines, 12 lung cell lines, 11 colon cell lines, 10 breast cell lines, 4 pancreas cell lines, 2 prostate cell lines, 2 stomach cell lines, and 6 cell lines of 6 other types of tissues. A total of 403 probes were customized to estimate the isoform expressions of 155 cancer genes curated from the literature with more reliable isoform annotations, where each of the 155 gene contains at least two isoforms.

ConclusionsManagement of patients with advanced rectal cancer and radiologically positive lateral pelvic lymph nodes is challenging due to high local recurrence rates. Further studies are needed to develop care pathways for the optimal treatment processes.
