The Lambowitz Lab


The Lambowitz Lab recently took this picture as a going away gift to Manabu, one of our post-docs who is returning to Japan this month.
I'll introduce you to the members of the lab.
Starting on the far left standing behind the chairs:
1) Sabine is a longtime member of the lab. She came with Dr. Lambowitz from Ohio State University. She is a German scientist who's husband also works in the lab. Sabine does mostly biochemisty experiments while elucidating the mechanisms of RNA folding and RNA splicing.
2) Paul was previously a graduate student in the lab. He is now a post-doc and works on determining the molecular structure of RNAs and proteins.
3) Marta is a senior lab techician. She works predominantly on gene targeting in Xenopus laevis (the African clawed frog). Marta works closely with Fang Lei on these projects. Since she is from Italy, Marta is often asked for culinary advice.
4) Mark is another protein biochemist. He came to the lab from the University of Miami. He works with Sabine and Paul to determine the activity of proteins involved in RNA splicing.
5) Junhua recently graduated from the PhD program. She has been working in our lab to understand the localization of our protein of interest in bacterial cells. She has shown that the protein tends to be localized to the poles of bacterial cells. Since I've known Junhua she has gotten married and had her first child.
6) Lawrence is a senior lab technician who specializes in cell culture. He spends most of his time in the cell culture room performing experiments on human and mouse cells. He is an important member of the eukaryotic gene targeting project. He advises me on my cell culture experiments and helps all of us troubleshoot our experiments.
7) Jun is a Chinese graduate student who works on bacterial gene targeting. He has been very productive in developing targeting systems for various types of bacteria. His work is potentially significant for battling pathogenic bacteria to help fight diseases and bio-terrorism.
8) That's me in the back there.
9) Travis is an American graduate student who is a part of the eukaryotic gene targeting project. His experiments are very similar to mine. We both are trying to target genes in human cells and other multicellular organisms. Travis is a native Texan.
10) Joe is a recent addition to the eukaryotic gene targeting team. He came from an industry job and has recently completed his first year in the cell and molecular biology program. Joe is also trying to use group II introns to target animal genes.
11) Shanquin is a Chinese post-doc who came to the lab from a German laboratory. He works on UV crosslinking of intron RNA to RNA-binding proteins in order to determine RNA structure and RNA-protein interactions. His experiments basically consist of exposing RNA molecules bound to proteins to ultraviolet light so that nucleotides in close proximity to the protein will form covalent bonds. Determining where the protein and RNA form these bonds allows for RNA and protein structure predictions.
12) Georg is a German scientist and longtime member of the lab. He is married to Sabine. He works on the evolutionary relationships of RNA binding proteins among many other things. He also works to determine the activity of these proteins in bacterial cells. His work allows us to understand the mechanisms of RNA binding proteins and reverse transcriptase protein including the HIV reverse transcriptase.
13) Jake is a Biochemistry graduate student. He has been studying DNA target recognition by the group II intron ribonucleoprotein. His experiments are somewhat related to Shanquin's.
In the front row seated from left to right:
14) Fang Lei is a Chinese graduate student. She works closely with Marta to target genes in the African clawed frog (Xenopus laevis). Her experiments involve isolating nuclei from frog sperm and performing targeting of the frog genome in vitro (in a test tube). After targeting the sperm nuclei, she injects the targeted nuclei into unfertilized frog eggs and screens for intron-containing embryos.
15) Asaka and Alain are Manabu's wife and son. It amazes me that I have been here long enough for the birth of Manabu's son and to watch him grow into a little boy.
16) Manabu is a Japanese post-doc who is returning to Japan. He has been a very important contributor to the lab. He has performed significant biochemical experiments that help us understand the behavior of the group II intron RNP. He recently joined the eukaryotic gene targeting team and made great strides to push us forward in our experiments. His contributions have significantly improved my experiments and he has taught me a lot about designing my experiments. He will be missed.
17) Alexis is a new graduate student in the lab. She works closely with Jun on the bacterial gene targeting project.
18) Alan is the boss. He has put together this great group of scientists and he keeps us all on task...a huge endeavor!
19) Roland is another longtime member of the lab. He is a jack of all trades. He specializes in developing expression systems for bacteria and yeast cells. I think of him as "the book" because he is truly a resource more complete than Wikipedia. If I have a problem, Roland is the first person I think to ask.
Believe it or not, some members are not present.
Sinjong, Cheryl, Jessica, Lauren and our undergraduate techs are not pictured.
So, that's the lab.

What's new?

Well, it's summer in Austin which means it's really heating up. Cara and I are busy as usual. Even though Cara has recently completed her second year as Assistant Band Director at Henry Middle School, she is still very busy teaching private lessons and counseling/teaching at UT and ECU band camps this month. In addition, she is already practicing her music for her performance with the UT Wind Ensemble at the festival del sole in Napa Valley California in July. We are both very excited about this event because neither of us has been to Napa Valley. I am excited to hear the Corigliano piece, again. It is the same piece that Cara and the UT Wind Ensemble performed in Carnegie Hall. As for me, I'm still working daily to finish my graduate research for my PhD. I know that I've been in Austin for a long time and I would love to be wrapping things up, but my project has proven to be a much bigger challenge than I originally anticipated. When I arrived at UT and began work on this project, there were only two people working on eukaryotic gene targeting in mammalian cells. Since I have been here, we have expanded our team to about 10 people including 2 Post-doctoral fellows, 5 graduate students, 2 technicians and undergrads. We have also expanded the scope of the project from only mammalian cell culture to mice, frogs, zebrafish, and fruit flies. I have shown that group II introns are capable of integrating into DNA targets in fruit flies and zebrafish and we have patented this discovery. However, our main goal of obtaining a living organism that possesses a disrupted gene via an integrated intron at a chosen target site has remained elusive. I have some data that suggests that I have successfully disrupted the CCR5 gene in human cells which would be a major breakthrough. The CCR5 gene encodes a cell membrane protein that is recognized by HIV to infect human T cells. Disrupting this gene makes cells resistant to HIV infection. Unfortunately, I have not been able to defintively confirm the integration, so I must trudge on. It is my full intention to see this project through to the end, but I fear that time is moving faster than my progress. Recently, I took on another project that is much more likely to lead to data that will allow me to graduate in a reasonable time-frame. This project involves studying a group II intron from E. coli that has been shown to have retargeting capabilities. We will be looking at the very basic mechanisms by which this intron targets DNA. I feel very comfortable with this project and if it proves to be productive, it will reduce some of the pressure that I put on myself to graduate. I believe that as I progress on this new project, I will be able to focus more on the eukaryotic gene targeting project without feeling like my life depends on the eukaryotic project. So, that's the most I've ever written about my graduate research on my blog. I think I'll leave that subject for now.
This summer for me will also be lots of fun. We just returned from a short trip to NC to get some much needed R&R. It was wonderful to see our friends and family in NC. And soon, Mom will be coming to visit with my niece, Emily. I'm really looking forward to their time in Austin. I can't wait to show Emily some of the really fun and cool places that we have here in Austin. In July, I'll be joining Cara at the festival del sole. That will be an amazing experience. I can't wait to hear her play again and I'm sure that we will visit some of the vineyards and wineries. I'm also excited to go to San Francisco. Cara's never been to S.F. but I have. I've learned so much about S.F. since my visit that I'm very excited to return to the Bay City. In August, we're planning to go to Cara's cousin, Angela's wedding and in the same week, I'm supposed to go to a Yankees/Red Sox baseball game. I'm hoping that Roger Clemens will be pitching. Well, that's the update for now. If you'd like to comment, please shoot me an email. I love hearing from family and friends.
Cheers!

I think I've got a crush on John Edwards!

So, yesterday Former North Carolina Senator and Presidential Candidate John Edwards came to Austin. He gave a speech at Schultz's Beer Garden in downtown Austin. I was late to the event so I missed most of the speech, but afterwards he stuck around for questions. I stuck around, as well, shook his hand and wished him well. At one time, I thought that John was going to be my pick for President in '08, but since he has gone with the radical left on the war, I have presently changed my position. I'm not sure that his plan for an immediate withdrawal of troops is in the best interest of America's Middle East policies. I can't believe that I would say this, but I agree more with Hillary's message that withdrawing troops immediately following the installation of the next president will be a disaster. However, his populist approach is appealing on some level and I believe in universal health care for many reasons including what I feel is most important: preventative care based on genetic testing.
He is a good-looking man, though...I may be developing something of a crush. ;)

Trip to Wilmington, NC

We had a blast this weekend in Wilmingon, NC. Cara and I visited Shaun and Christin and Cristin and Shawn and my Mom. We spent a fair amount of time on the beach and we had a lot of good ol' North Carolina fine dining at Bojangle's, the Sawmill and the George. We were blessed by a special visit from Tropical Storm Barry on Sunday, but it blew through pretty quickly leaving some nice swells. I was very happy to get out there and test my hand at surfing again. It took me a while to catch some waves, but once it started happening, I felt like I was in high school again.
We also met with Brandon, Brian, Jason and Jamey for a night on the town. And my high school buddy, Dave, joined us out for a couple of nights, as well. It was really great to see everyone again and I can't wait to get back to NC, soon. We have several opportunities to see some of our friends again...Brian's wedding is coming, Austin City Limits Festival is always beckoning and we'll be in NJ in August. What a weekend! Life is good!!!
Look Christin, you're a YouTube star!


Cara's parents come to visit

We always love it when we have guests, especially the DeFranks! We get to do things that we wouldn't normally do and it's so much fun. During their visit we had lots of good food including the usual Austin staples - Maudie's Tex Mex and Rudy's BBQ. We also went to Fredericksburg, TX for a day of shopping. And before they left we went to Cara's spring concert. It was a great time! Thanks, Mom and Dad.


Backyard Party Anyone?

Thanks to Cara's parents, we recently relandscaped our backyard. Cara and I love it and the doggies are really happy to be able to play in the backyard again.
Here's a few pics of the project.

Meet Nobel Laureate Ferid Murad


This is a picture of Dr. Ferid Murad, FangLei Zhuang (a friend and fellow Lambowitz lab member) and myself at the graduate student potluck dinner following the Paul D. Gottlieb Lecture. Dr. Ferid Murad recently gave a lecture as part of the Paul D. Gottlieb Lecture Series at UT Austin. Dr. Murad received the Nobel Prize in 1998 for for his discoveries concerning nitric oxide as a signaling molecule in the cardiovascular system. His discoveries led to the development of cardiovascular drugs such as Viagra. I am very appreciative for Dr. Murad's willingness to come to UT upon our invitation. My friends and I initiated the Paul D. Gottlieb Lecture series in 2003 and we have been fortunate to bring 4 Nobel Laureates to Austin as part of the series. In the fall, I will be the official host for Dr. James D. Watson, co-discoverer of the structure of DNA. Dr. Watson is one of the most famous scientists of the last century. I am excited that he has accepted our invitation to come to UT.

My Boogie Bahn Blooper

Cara and I went to Schlitter Bahn on Saturday with her students. We didn't partake in too many of the attractions, but my withdrawals for surfing forced me to try the Boogie Bahn. Take a gander at these skills!

Six Flags Over Texas

Here's a short video clip of our trip to Six Flags over Texas for Cara's Middle School Band Trip.

Mary Matalin and James Carville speak at the University of Texas at Austin

James Carville was actually very entertaining while discussing contemporary politics. He makes some very interesting predictions.

Dedicated to those seeking love

I've been fortunate to find the love of my life. One way that I know that I'm in love is because sometimes it seems that no matter where I look, I am surrounded by love. For some, though, love seems hard to come by. The message in this video is that love is where you find it...sometimes it's in the least expected places.

Birthday Party for Ishmael Soto

This weekend Cara and I went to a birthday party for Ishmael Soto. Ishmael is the father of one of Cara's private lessons students and he happens to be an accomplished sculptural artist. The party took place at the Mexic-Arte Museum in downtown Austin, Texas where he currently has an exhibition of his work.
