The crystal structure of ClpP protease activated by the experimental Phase 2 anti-cancer drug ONC 201, as determined by graduate student Ondrej Halgas in Emil F. Pai’s lab, was featured on the cover of the current issue (May 13th, 2019) of the journal Cancer Cell. Together with the laboratories of Walid Houry, Aaron Schimmer (Medical […]

The Ion Transporter NKCC1 Links Cell Volume to Cell Mass Regulation by Suppressing mTORC1

15 May 2019|0 Comments

Wael Demian from the Rotin lab at Sickkids, recently published a Cell Reports paper showing that the ion transporter NKCC1, known to regulate cell volume, forms a complex with the leucine transporter LAT1 and the Gln transporter ASCT2, and regulates mTORC1 activation via LAT1 and growth factors signaling. Thus, the work of Demian, et al. […]

By Matthew Pariselli

In a new eLife paper, Dr. David Andrews, a senior scientist at Sunnybrook Research Institute, and his lab show how an interaction between proteins promotes cancer cell survival.

Andrews, who is also a professor in the department of biochemistry at the University of Toronto, discovered that Bim, a pro-cell-death protein, binds to anti-cell-death proteins […]

DNA Replication Stress Causes Mutations

4 March 2019|0 Comments

Grant Brown’s lab at the Donnelly Centre has characterized a new mutagenic ssDNA gap filling pathway in budding yeast. Their findings will be published in the March 7th issue of Molecular Cell.

DNA replication is a fundamental process that occurs before every cell division and must be completed in a timely and accurate fashion. Under normal […]

How to protect Peroxisomes and Mitochondria from Dying

6 February 2019|0 Comments

The regulation of organelle abundance is critical for cell function and survival; however, the mechanisms responsible are not fully understood. Imbalances in organelle abundance can result in disease states, including Parkinson’s Disease resulting from dysregulated mitochondrial homeostasis. Peroxisome dysregulation also results in disease, most notably the Zellweger’s spectrum disorders. Although first considered to be caused […]
