Read MoreThis enclosure gives us precise temperature control, and provides the added benefit of blocking out stray light from the room. See the photos from installation to completion below!
Read MoreWe've been following Stanford guidelines to slowly make the transition back to lab. Progress is ramping back up and we are keeping ourselves/others safe by wearing masks, washing our hands, and keeping a 6-foot distance. Please stay well, everyone! It's good to be back!
Read MoreThis beautiful piece was created by an incredibly talented independent artist - Sarina Mitchel to illustrate the key steps in the repair of a very toxic form of DNA damage called DNA Protein Crosslinks. The artwork was originally intended as a cover proposal to accompany Gheorghe's postdoc paper "The CMG Helicase Bypasses DNA-Protein Cross-Links to Facilitate Their Repair" (Sparks and Chistol et al, 2019). Alas - the journal editors chose a different image, but we felt that the art deserves to be seen and enjoyed, so it became our website landing image.
The eukaryotic replicative helicase CMG unwinds double-stranded DNA by threading
one DNA strand through a narrow pore in the center of the helicase while sterically
excluding the other strand. Covalent DNA-protein crosslinks (DPCs) are bulky DNA
lesions that impede replication by acting as roadblocks in the path of the helicase. Sparks & Chistol et al. dissect how the replicative helicase copes with DNA-
protein crosslinks using Xenopus egg extracts and a combination of ensemble and
single-molecule approaches. This study found that, surprisingly, the replicative helicase
bypasses intact DPCs, and that bypass triggers DPC proteolysis. The artwork is an
artistic representation of various stages of DPC (orange) bypass by CMG (green) aided
by the accessory helicase RTEL1 (magenta). Image by Sarina Mitchel Art & Illustration.
The microscope was one of the first things we ordered (actually pre-ordered during the summer). It's coming together as we speak, with the help of Brian and Thomas from Nikon - thanks guys!
Read MoreLinda and Gheorghe are on a massive ordering spree, buying everything needed for a lab: a Nikon microscope, centrifuges, lab supplies, and - most importantly - lab snacks!
