Eric- Week 4: Happy Fourth of July

This week was my first without the other high school volunteers. I was excited to be working with my postdoc on more advanced techniques, including: qPCR, RNA purification, DNA purification, and subcloning. My fourth week was shorter because the lab gave me off two days for the Fourth of July. Liz told me to spend a few days on writing a protocol for my subcloning project (where I am making vector-plasmids have a modified gene inserted) and another protocol for my RNA purification. The other times during the week were based on me helping Liz with some of her experiments. She asked me to run a PCR and gel for a specific set of primers and her lncRNA, PACER. Liz told me that she never got bands from the PCR because the sequence is very hard for the primers to properly bind to, and there are many places where the experiment goes wrong. Luckily, out of the five mice I genotyped, two displayed the presence of the lncRNA. Liz was really happy because she wanted to be reassured that she had both KO mice and the WT mice.

In addition to getting the very difficult PCR to work, I started my RNA purification experiment, where I used 27 different samples from cells treated differently with high-density lipoproteins, low density lipoproteins, and lipopolysaccharide. The purpose of this experiment is for me to eventually use qPCR and determine if PACER is expressed differently when treated different ligands, specifically those involved in cardiovascular diseases.

The best thing I got to do with the lab this week was to go to the Penn Museum. One of the Research Associates, Damien, used to work at the museum and is kind of a history buff. He offered to show everyone the "secrets of the museum", although after the fact, there really are not that many surprises from the museum.

Hopefully everyone else has enjoyed their holiday, and are enjoying working in the other labs.

Kylie Heering, Week 2 at the Goldstein Lab

We started off our week with a congratulatory acai bowl trip to celebrate Preston’s acceptance into a training grant program. Acai bowls in California top Playa Bowls (no question about it). From what I can tell, its a pretty huge honor to be recognized by this grant, but he’s really humble about it. On Monday, Preston and I decided that testing antibodies that have never been tested on prostate epithelial cells before would be a good objective for my first Western blot on my own. We needed to probe for ASCT2, a glutamine transporter, and GLS in order to determine if their corresponding antibodies are functional. Antibodies are crucial for Western blots because they bind to the protein of interest (POI), allowing for us to qualify its expression after imaging. As such, Preston wanted to make sure they worked by probing for ASCT2 and GLS on three different cell lines. Cell lines are commercially purchased human cells that have been immortalized (modified to grow indefinitely) by telome...

Alan - First Week at UCSF

Hi Everyone! After arriving in San Francisco last Sunday, I spent this past week settling into the downtown Berkeley apartment that I’ll be sharing with Rohit for the next couple of months, as well as learning my way around the Roy lab at UCSF. First day at the lab was really exciting. Here are a couple pictures of the Mission Bay campus, which was completed just a few years ago. Everything is super new and modern, and there’s still construction for other buildings going on around the campus. Most of the people who work at the Mission Bay campus are either professional researchers or doctors/nurses for the nearby hospital. The graduate students take most of their classes at the original Parnassus campus (where Maya is). I work in Byers Hall, which is connected to Genentech Hall and a short walk down the block from the shuttle stop. There are three other volunteers working for the Roy lab this summer – Kimmai, David, and Pujita, who are all undergrad college students...

Wendy Li, Week 1

It is now early July and I have finally started my lab work. I arrived there at about 9 am on the very first day of my lab and found out that there were only two people in the office—Alex, a graduate student in engineering school, and me. “There should be more people in the office, but most of them went to a vacuum workshop today.” Alex told me. My work officially started at 10:30 am when my post doctor Subarna came to the lab. Familiarizing me with all the facilities in lab, Subarna first gave me a lab tour. Meanwhile, he showed me all the basic operations with vacuum chamber, ellipsometer, as well as the spin coater. During the rest of this past week, I was in the process of making my own films. I learned to cut Si wafer into 1*1 cm pieces and clean the surface of these Si wafer with duster and plasma which can effectively clean up all the extra organic particles from the wafer. Further, I prepared 10 percent polystyrene (PS 8000) toluene solution as the material for spin coating. ...
