Application Areas of Traditional Molecular Genetic Methods and NGS in relation to Hereditary Urological Cancer Diagnosis.

J Oncol 2020 17;2020:7363102. Epub 2020 Jun 17.

Laboratory of Epigenetics, Research Centre for Medical Genetics, Moscow 115522, Russia.

Next generation sequencing (NGS) is widely used for diagnosing hereditary cancer syndromes. Often, exome sequencing and extended gene panel approaches are the only means that can be used to detect a pathogenic germline mutation in the case of multiple primary tumors, early onset, a family history of cancer, or a lack of specific signs associated with a particular syndrome. Certain germline mutations of oncogenes and tumor suppressor genes that determine specific clinical phenotypes may occur in mutation hot spots. Read More

Mechanistic Models of Signaling Pathways Reveal the Drug Action Mechanisms behind Gender-Specific Gene Expression for Cancer Treatments.

Cells 2020 Jun 29;9(7). Epub 2020 Jun 29.

Clinical Bioinformatics Area. Fundación Progreso y Salud (FPS). CDCA, Hospital Virgen del Rocio, 41013 Sevilla, Spain.

Despite the existence of differences in gene expression across numerous genes between males and females having been known for a long time, these have been mostly ignored in many studies, including drug development and its therapeutic use. In fact, the consequences of such differences over the disease mechanisms or the drug action mechanisms are completely unknown. Here we applied mechanistic mathematical models of signaling activity to reveal the ultimate functional consequences that gender-specific gene expression activities have over cell functionality and fate.

[Carcinoma of the colon with bladder invasion; what is the role of preoperative chemotherapy?]

Ned Tijdschr Geneeskd 2020 Jun 25;164. Epub 2020 Jun 25.

Radboudumc, afd. Heelkunde,Nijmegen.

Preoperative chemotherapy followed by surgery was applied in three patients, aged 68 years (male), 48 years (female), and 80 years (male) with locally advanced cancer of the colon with bladder invasion. Achieving a resection with free margins (R0) is essential in colon-cancer surgery, but the role of preoperative chemotherapy in colon cancer remains unknown. When a tumour is presumed to be unresectable, guidelines recommend discussing the case and possibly referring the patient to an oncological expertise centre, where each patient will be individually assessed for the most suitable preoperative treatment and surgery during a multidisciplinary tumour board meeting.

The miR-140-5p/KLF9/KCNQ1 axis promotes the progression of renal cell carcinoma.

FASEB J 2020 Jun 28. Epub 2020 Jun 28.

Guangdong and Shenzhen Key Laboratory of Male Reproductive Medicine and Genetics, Peking University Shenzhen Hospital, Clinical College of Anhui Medical University, Shenzhen, China.

Although renal cell carcinoma (RCC) is a common malignant urological cancer, its pathogenesis remains unclear. Previous studies have indicated that miR-140-5p acts as a tumor suppressor in various tumors, including bladder cancer, hepatocellular carcinoma, and gastric cancer, but its biological function in RCC remains unknown. In the present study, we found that miR-140-5p was upregulated in RCC tissues, whereas Krüppel-like factor 9 (KLF9) was downregulated and correlated inversely with miR-140-5p in RCC tissues.

A SNP of miR-146a is involved in bladder cancer relapse by affecting the function of bladder cancer stem cells via the miR-146a signallings.

J Cell Mol Med 2020 Jun 28. Epub 2020 Jun 28.

Department of Urology, The First Affiliated Hospital of Zhengzhou University, Zhengzhou, China.

MiR-146a-5p in urine samples was recently reported to be possibly used as a prognostic marker for bladder cancer (BC). Interestingly, YAP1 and COX2 were both demonstrated to function as stem cell regulators in BC. Therefore, in this study, we aimed to establish the molecular mechanism underlying the role of miR-146a, YAP1 and COX2 in BC relapse. Read More

Identification of an Individualized Prognostic Signature Based on the RWSR Model in Early-Stage Bladder Carcinoma.

Biomed Res Int 2020 4;2020:9186546. Epub 2020 Jun 4.

College of Computer Science and Technology, Jilin University, Changchun, Jilin, China.

Bladder cancer (BLCA) is the fourth common cancer among males in the United States, which is also the fourth leading cause of cancer-related death in old males. BLCA has a high recurrence rate, with over 50% of patients which has at least one recurrence within five years. Due to the complexity of the molecular mechanisms and heterogeneous cancer feature, BLCA clinicians find it hard to make an efficient management decision as they lack reliable assessment of mortality risk.
