Randomness in Cancer Breakpoint Prediction.

J Comput Biol 2021 Jun 15. Epub 2021 Jun 15.

Laboratory of Bioinformatics, Faculty of Computer Science, National Research University Higher School of Economics, Moscow, Russia.

Cancer genomes are susceptible to multiple rearrangements by deleting, inserting, and translocating genomic regions. Recently, the problem of finding determinants of breakpoint formations was approached with machine learning methods; however, unlike cancer point mutations, breakpoint prediction appeared to be a more difficult task, and various machine learning models did not achieve high prediction power often slightly exceeding the threshold of random guessing. This raised the question of whether the breakpoints are random noise in cancer mutagenesis or there exist determinants in structural mutagenesis. Read More

Lysyl oxidase inhibitors attenuate cyclosporin A-induced nephropathy in mouse.

Sci Rep 2021 Jun 14;11(1):12437. Epub 2021 Jun 14.

Renal Medicine, Kolling Institute, Royal North Shore Hospital, University of Sydney, Sydney, NSW, Australia.

Calcineurin inhibitors, such as Cyclosporin (CsA), are the mainstay of anti-rejection therapy in solid organ transplants but can paradoxically induce progressive nephropathy characterised by renal dysfunction and interstitial fibrosis. Lysyl oxidases (LOXs), a group of enzymes that catalyse extracellular matrix (ECM) crosslinking, were shown to implicate in tissue scarring. It is hypothesized that inhibition of these enzymes may render therapeutic effects against CsA-induced nephropathy. Read More
