Research identifies new breast cancer therapeutic target

(Louisiana State University Health Sciences Center) Research led by Suresh Alahari, PhD, Professor of Biochemistry and Molecular Biology at LSU Health New Orleans School of Medicine, has shown for the first time that a tiny piece of RNA deregulates energy metabolism, an emerging hallmark of cancer. The finding identifies a new target for therapeutic intervention in breast cancer.

Authors: Mayrovitz H Abstract Obesity is linked to the risk of breast cancer and treatment-related lymphedema (BCRL). Thus, knowledge of how obesity, or more specifically total body fat percentage (TBF) and body mass index (BMI), affect measurements that are used to detect or track lymphedema is clinically important. Tissue dielectric constant (TDC) is one measure used to help characterize lymphedema features, detect its presence, and assess treatment-related changes. The goal of this research was to determine the extent to which TDC values depend on TBF and BMI. TDC was measured on both forearms (2.5mm depth) in 2...

This study aimed to establish diagnostic accuracy of interlimb differences of ultrasonographic subcutaneous tissue thickness measurements in breast cancer-related arm lymphedema. We compared the truncated cone method by using circumference measurements and interlimb differences of ultrasonographic subcutaneous tissue thickness measurements to evaluate the diagnostic accuracy of interlimb differences of ultrasonographic subcutaneous tissue thickness measurements. Sensitivity, specificity, receiver-operating characteristic (ROC) curve, and area under the curve (AUC) were used. Analysis of ROC curves yielded area under the cu...

Authors: Sun W, Shen NM, Fu SL Abstract Cervical cancer (CC) develops, after human papillomavirus (HPV), an infection transmitted through sexual contact. Worldwide estimates are around>500,000 CC diagnoses and>300,000 related deaths annually, and CC remains the second most devastating type of cancers in women after breast cancer. Although the vaccine against HPV has reduced the incidence of infection and the treatment efficacy of the early-stage diagnoses has improved, many challenges remain in terms of treatment efficacy, during the late-stage and prevention of chemotherapy resistance development. Thus, new ...
