The lab is proud of Siqi’s new manuscript published in Angiogenesis that describes novel pro-angiogenic roles for RIPK3. This study adds to our lab’s growing evidence that RIPK3 can play beneficial roles in endothelial cells, in addition to detrimental ones when it is overexpressed.

The Griffin Lab thoroughly enjoyed NAVBO’s online Vascular Biology 2020 meeting, despite the ice storm that hit OKC early in the meeting and compromised power/internet for many of us. Congrats to Matt and Charmain for their oral presentations selected from abstract submissions and to Melinda (circled below) for winning an Outstanding Poster Award from the Vascular Inflammation Workshop!

The Griffin lab was full of smiles and tears today as we celebrated Siqi’s successful Ph.D. defense! We will miss Siqi’s amazing presence in the lab but are excited that she’s staying in the vascular field, as she begins her postdoc with Dr. Mark Kahn at U. Penn next month. Many congrats, Siqi, for a fantastic graduate career and bright future!

Congrats to Chris Schafer for his newly published manuscript in PNAS describing a novel way to regress pathological blood vessels in mouse eyes. Many thanks as well to our collaborators across the street at the Dean McGee Eye Institute and to George Davis at USF.

The lab just said “goodbye” to its 4th student from the Visiting Graduate Traineeship Program–Katarzyna (Stacy) Borawska. Stacy spent the last year in the lab studying vascular development in the embryonic omentum with Dr. Matt Menendez. We wish her the best as she returns to Poland to defend her Masters thesis.

The Griffin lab said a fond farewell to Kasia Kurylowicz on Friday. Kasia came to our lab from Poland through the Visiting Graduate Traineeship Program two years ago and has contributed valuable effort to numerous projects. We will miss Kasia but are excited for her new opportunity to study cancer research at the University of Chicago in the lab of Dr. Shannon Elf.

Kasia worked closely with Dr. Chris Schafer during her time in the lab; they’re pictured here at Chris’ wedding in 2019.

Courtney is excited to have been elected as the next President of the North American Vascular Biology Organization (NAVBO). She will spend this year supporting the current President–Dr. Masanori Aikawa–in a President-Elect role and will take over the reigns in July 2021.

The Griffin lab is grateful to be back at the bench after the COVID-19 lockdown…albeit on staggered shifts and with plenty of social distancing for safety!

Siqi, Charmain, and Melinda are masked and ready to research…6 feet apart!

Courtney is honored to have been named the Scott Zarrow Chair in Biomedical Research at OMRF’s spring board meeting. Special thanks to the Anne and Henry Zarrow Foundation, which endowed this chair in memory of Tulsa attorney and philanthropist Scott Zarrow.

Congratulations to Sarah Colijn for her new cover-featured article in Disease Models & Mechanisms about an unexpected athero-protective role for RIPK3 in endothelial cells and macrophages.

We are excited to welcome two new graduate students to the lab: Bridget Parrish and Rahul Rajala. Thanks to you both for choosing to train in the Griffin Lab!

Congrats to Charmain Fernando for her new AHA Postdoc Fellowship on the role of RIPK3 in ischemia/reperfusion injury…way to go, Charmain!

Stacy will be working closely with Matt over the next year studying the impact of peritoneal macrophages on vascular integrity. Thank you, Stacy, for traveling so far to do research with us!

We are delighted to have Abby Williams working in the lab this summer. Abby is a rising freshman at New York University and is spending several weeks helping Melinda study organ-specific roles for endothelial BRG1 and CHD4.

The Griffin lab is pleased to host Kate Wheeler as an OMRF Fleming Scholar this summer. Kate is a rising freshman at the University of Oklahoma and had visited our lab several times during her high school years to learn more about our research. This summer she is working with Siqi on studying novel intracellular roles for RIPK3, and we’re already so grateful for her hard work and dedication to her project.

Congrats to Sarah Colijn, Siqi Gao, and Kyle Ingram for acceptance of their manuscript on RIPK3 by Cell Death & Differentiation. This paper defines novel transcriptional regulators of Ripk3 and demonstrates that excessive endothelial RIPK3 expression causes embryonic vascular fragility.

Courtney is grateful to have been awarded OMRF’s Edward L & Thelma Gaylord Prize for Scientific Excellence. This award reflects all the hard work and creativity displayed by current and former lab members over the last several years…thank you!

Congrats to Matt Menendez and former Griffin lab postdoc E-Ching Ong on their new ATVB paper showing a role for BRG1 in establishing capillary integrity.

We are grateful for the dedication and hard work of two individuals departing our lab this month. Anna Drozd spent the last year with us as a Visiting Scholar from the University of Lodz in Poland. She worked closely with Matt Menendez in studying the role of BRG1 in lymphatic development. We are excited that she is entering a PhD program at the University of Copenhagen this fall. Jocelyn Rodriguez spent three weeks with us as a Saxon Scholar studying the interaction of CHD3 and CHD4 in early vascular development with Chris Schafer. She will start her junior year this fall at the U.S. Naval Academy. Both of these young women were an asset to our lab, and we’ll miss their wonderful personalities and sharp scientific minds. Best of luck in your future endeavors, Anna and Jocelyn!
