1. Rebooting twitter (last tweet 7yrs ago!) for lab, now an apt time for intro #threads on Lok lab's bckgrnd. Mission is to improve the outcomes of lung cancer patients by developing novel therapeutic strategies(esp. related to DNA repair) + understanding resistance mechanisms
Thanks @drshieldsmd !
Excited that you're co-leading the @IASLC SCLC subcommittee with Dr. Shigeki Umemura - great job with your team!
Congratulations Dr. Benjamin Lok @BenLok @pmcancercentre for receiving the Heine Hansen Lectureship Award for Small Cell Lung Cancer at @IASLC #WCLC26. So incredibly well deserved! Kudos! 👏
@SclcSMASHERS @LUNGevity
Very grateful to @IASLC for the Heine H. Hansen Award for SCLC on behalf of all patients, my team at @pmcancercentre @PMResearch_UHN @RadMedPM @UHN_Research @UHN, my family, and attendees at #WCLC26
Thanks to Marcia Horn @WarOnCancer for a picture of me on the jumbotron 📺😀
Congratulations to Dr. @BenLok on receiving the Heine H. Hansen Lectureship Award for Small Cell Lung Cancer (SCLC) from @IASLC for his sustained practice-changing contributions in understanding DNA repair mechanisms & improving patient outcomes in SCLC.

Researchers at @PMResearch_UHN have identified a potential new target to enhance radiation therapy for #SmallCellLungCancer.
Blocking HDAC3 protein function makes cancer cells more sensitive to radiation.

A team led by Dr. @BenLok @UHN has found a new target to enhance radiation therapy in small cell lung cancer. By removing the function of gene HDAC3, cancer cells became more sensitive to radiation and tumour growth was inhibited:

🧬 The team also found that PRMT inhibitor could improve SCLC treatment outcomes from an epigenetic point of view: A PRMT inhibitor (MS023) disrupts splicing, increases DNA damage & shows strong synergy with chemo & radiation.

🔬 New strategy to boost immunotherapy for small cell lung cancer (SCLC): Combining PARP inhibitors + radiotherapy activates immune pathways & boosts T cell-attracting chemokines, discovered by @BenLok’s team at @UHN @pmcancercentre.

How do immunogenic radiosensitizers work?
Unexpectedly, we found they also decrease a mRNA degrader, EIF4E2, ultimately contributing to increased T cell attractant chemokines and immunotherapy efficacy in preclinical models.

#ASTRO24
Terrific early morning #lungcancer session🫁‼️
@BenLok reporting on tolerability of PARPi with IMRT as consolidation in patients with ES-SCLC🙏
Important to restrict esophagitis‼️
Excellent basis for future development of PARPi in this space👍 #LCSM

This week marks 1 year since we initiated NET tissue biobanking. Today, we received tissue samples from the 40th patient.
We want to take this opportunity to express our deep gratitude to all the patients who have generously donated samples.
