Cancer-associated miRNAs and their therapeutic potential.

J Hum Genet 2021 Jun 4. Epub 2021 Jun 4.

Department of Molecular Cytogenetics, Medical Research Institute, Tokyo Medical and Dental University (TMDU), Tokyo, Japan.

MicroRNA (miRNA; miR) is a functionally small non-coding RNA and can negatively regulate gene expression by directly binding to the target gene. Some miRNAs are closely involved in the development and progression of cancer and are abnormally expressed in many cancer types. Therefore, control of the expression of cancer-associated miRNAs is expected as a next-generation drug modality to treat advanced types of cancers with high unmet medical needs. Read More

Active participation of membrane lipids in inhibition of multidrug transporter P-glycoprotein.

Chem Sci 2021 Apr 9;12(18):6293-6306. Epub 2021 Apr 9.

NIH Center for Macromolecular Modeling and Bioinformatics, Beckman Institute for Advanced Science and Technology, Department of Biochemistry, Center for Biophysics and Quantitative Biology, University of Illinois at Urbana-Champaign Urbana IL 61801 USA

P-glycoprotein (Pgp) is a major efflux pump in humans, overexpressed in a variety of cancers and associated with the development of multi-drug resistance. Allosteric modulation by various ligands (, transport substrates, inhibitors, and ATP) has been biochemically shown to directly influence structural dynamics, and thereby, the function of Pgp. However, the molecular details of such effects, particularly with respect to the role and involvement of the surrounding lipids, are not well established. Read More

J Oral Rehabil 2021 May 25. Epub 2021 May 25.

Department of Oral Medicine, Seoul National University Dental Hospital, Seoul, Korea.

Background: The current diagnostic criteria for temporomandibular disorders (TMD) do not require imaging for the diagnosis of degenerative joint disease (DJD) of the temporomandibular joint (TMJ) condyle, and there is a lack of data investigating the effectiveness of imaging modalities in predicting long-term TMJ DJD prognosis.
