Cancers, Vol. 11, Pages 1583: CD200 Induces Epithelial-to-Mesenchymal Transition in Head and Neck Squamous Cell Carcinoma via β-Catenin-Mediated Nuclear Translocation Cancers doi: 10.3390/cancers11101583 Authors: Seung-Phil Shin A-RA Goh Hyeon-Gu Kang Seok-Jun Kim Jong-Kwang Kim Kyung-Tae Kim John H Lee Yong-Soo Bae Yuh-Seog Jung Sang-Jin Lee The membrane glycoprotein CD200 binds to its receptor CD200R1 and induces tolerance, mainly in cells of the myeloid lineage; however, information regarding its role in solid tumors is limited. Here, we investigated whether CD200 expression, which is enriched mainly in high-grade head and neck squamous cell carcinoma (HNSCC), correlates with cancer progression, particularly the epithelial-to-mesenchymal transition (EMT). The forced overexpression of CD200 in the HNSCC cell line, UMSCC84, not only increased the expression of EMT-related genes, but also enhanced invasiveness. The cleaved cytoplasmic domain of CD200 interacted with β-catenin in the cytosol, was translocated to the nucleus, and eventually enhanced EMT-related gene expression. CD200 increased the invasiveness of mouse tonsillar epithelium immortalized with E6, E7, and Ras (MEER), a model of tonsillar squamous cell carcinoma. siRNA inhibition of CD200 or extracellular domain of CD200R1 down-regulated the expression of EMT-related genes and decreased invasiveness. Consistently, compared to CD200-null MEER tumors, subcutaneous CD200-express...

Publication date: Available online 20 November 2019Source: Urology Case ReportsAuthor(s): Eric M. Chevli, Tyler J. Maiers, David J. Abramowitz, Shervin Badkhshan, John J. BodkinAbstract:Situs inversus totalis (SIT) is a rare condition with left-right mirror imaging of both abdominal and thoracic organs. While this configuration is rarely of medical importance, an understanding of this unique anatomy is essential in the setting of surgical intervention. Here we review a case of renal cell carcinoma (RCC) in the setting of SIT. The patient underwent a hand-assisted laparoscopic radical nephrectomy. Pathology revealed pT3aNxM...

ConclusionsThese consensus statements provide further guidance on controversial topics in advanced and variant bladder cancer management until a time when further evidence is available to guide our approach.Patient summaryThis report summarises findings from an international, multistakeholder project organised by the EAU and ESMO. In this project, a steering committee identified areas of bladder cancer management where there is currently no good-quality evidence to guide treatment decisions. From this, they developed a series of proposed statements, 71 of which achieved consensus by a large group of experts in the field of...

Is there any difference in sensitivity to kidney function between men and women? Paterson et  al. have focused on sex differences in chronic kidney disease. Surprisingly, their experimental results show that only one microRNA, miR-146b-5p, affected the susceptibility of renocardiac pathology. They generated miR-146b knockout rats and found that miR-146b−/− females developed exacerbated renal hypertrophy and fibrosis and had less cardiac remodeling. Although miR-146b-5p has been reported to be upregulated in various types of cancers, this article reveals the novel role of miR-146b in the kidney.

The objective of this study is to assess information, motivation, and behavioral skills associated with willingness to receive an HPV test instead of a Pap test among women. The sample included U.S. 812 women, ages 30 to 65 years. Participants completed an online survey in 2018. The Information, Motivation, and Behavioral Skills (IMB) model was used to measure predictors of willingness for HPV testing. The outcome variables were willingness to receive the HPV test instead of the Pap test, with and without time interval details. Logistic regression modeling was used with SAS 9.4. Over half of the sample (55%) were willing...

Conclusions: Our findings suggest that some subsets of XPD patients may be at risk of radiosensitivity reactions and treatment with statins and bisphosphonates may be an interesting approach of radioprotection countermeasure. Different mechanistic models were discussed to better understand the potential specificity of the p.[Arg683Trp];[Arg616Pro] XPD mutations . PMID: 31738647 [PubMed - as supplied by publisher]

Conclusions: In this review, we examine the role of flavonoids as potential radiosensitizers, review the underlying molecular mechanisms and discuss their potential usefulness in improving cancer radiotherapy. It is emphasized that obtaining a deeper insight into the molecular mechanisms underlying the combined action of flavonoids and ionizing radiation may provide new directions for radiobiological research applicable to the much needed enhanced selective tumor cytotoxicity to treatment agents.

Conclusion MTDH is pro-oncogenic factor playing multifaceted and diverse roles in cancer progression. Its association and central role in regulating signaling pathways such a MAPK, wnt/β-catenin, PI3K/AkT, NF-κβ pathways in various cancers shows that it plays a vital role in metastasis. MTDH contribution to chemo and radiotherapy resistance provides a new direction for the development of anticancer therapeutics. Multiple mechanisms converge to promote expression of MTDH in cancers. Further studies are therefore warranted to determine whether the elevated MTDH expression has prognostic value for development...

Conclusion Most head and neck pathologies show a broad cellular heterogeneity making it difficult to achieve an accurate diagnosis and efficient treatment (Graf and Zavodszky, 2017; Lo Nigro et al., 2017). Single cell analysis of circadian omics (Lande-Diner et al., 2015; Abraham et al., 2018), may be a crucial tool needed in the future to fully understand the circadian control of head and neck diseases. It becomes more obvious that there is only a small genetic component but a largely unknown epigenetics and/or environmental component for most of the head and neck pathologies (Moosavi and Motevalizadeh Ardekani, 2016; He...
