Hi everyone ๐๐พ!
Iโm a Bioinformatician ๐ฉ๐พโ๐ป in a Cancer Genomics lab @SickKidsNews and I primarily work with the pediatric precision medicine program based out of my lab aimed at integrating NGS into clinical oncology care.

This isnโt a random scientist who got lucky.
Mariano Barbacid discovered the first human oncogene in 1982. He isolated H-RAS from bladder cancer cells and proved a single point mutation could trigger cancer. That finding launched the entire field of molecular oncology.
KRAS mutations cause 90% of pancreatic cancers. For 43 years, oncologists called KRAS โundruggableโ because the protein had no obvious binding pocket. Barbacid spent the last decade using genetically engineered mice to systematically test every node in the KRAS signaling pathway, looking for combinations that would work without killing the patient.
The triple therapy blocks KRAS three ways at once: the main growth signal, the escape routes through EGFR and HER2, and the stress-response backup through STAT3. Cut the engine, seal the exits, disable the emergency system. Tumors vanished in mice and didnโt return for 200+ days after treatment stopped.
Pancreatic cancer has a 13% five-year survival rate. 8% for the ductal adenocarcinoma type this therapy targets. Most patients live one year after diagnosis.
The catch: this is preclinical. Human trials are 3+ years away. One of the drugs, RMC-6236, might get approved this year, but the full triple combination has regulatory hurdles.
Still. The man who discovered human oncogenes in 1982 may have just figured out how to eliminate the cancer those genes cause. Thatโs a 43-year arc from first principles to potential cure. Science rarely works this clean.

New #SKResearch published today in @NatureComms: Dr. Adam Shlien, Senior Scientist, SickKids, & Dr. Rebecca Gladdy, surgeon-scientist, @SinaiHealth, have identified 3 subtypes of #leiomyosarcoma & found evidence its origins begin years prior to diagnosis. https://t.co/LYT5PH1N3V
An important conversation, the most striking is the gender/race gap in STEM. I always thought I was catching up by accumulating education but was hit w/ this reality back in 2019 https://t.co/6tG62tsCC8
Was in awe listening to Dr. Katalin Karikรณ describe the 60 years of mRNA research leading up to the mRNA COVID vaccines that I've had the privilege of putting into others' arms ๐. Fund basic science because the return on investment is huge. #RNAMedicine2021
@enbybird I was watching med content from @ericaogwumikee and her sister tag with @nnekaogwumike & @chiney came up... went down the rabbit hole and became instantly obsessed ๐
#BREAKING: Peel Region orders all businesses with 5+ recent work-acquired #COVID19 cases to shut down immediately.
Kudos to Dr Loh for doing what the government of Ontario wonโt do: Help save the lives of essential workers.
2. ... plus immense ashfall even blanketing neighbouring islands (which can have significant health and environmental impacts), all in the middle of a pandemic and youโre acting like the volcano had a calendar and picked a week to... inconvenience vacationers ?
1. I still canโt put into words how upset I am by this headline. Half of the island have had to leave their homes and lives behind and the entire island is dealing with constant explosive eruptions, water and power outages, limited access to food or even mattresses to sleep on...
