-\\ Hepatocellular carcinoma (HCC) is a the most common type of liver cancer and the third leading cause of cancer deaths in the world. The goal of project one is to identify the genes that are associated with regressing tumors (regardless of type of treatment) vs. those that are growing from the C3HeB/FeJ mouse model. Normal liver is used as a control. The results will be useful in identifying new therapeutic targets and potential drug combinations which could lead to more efficient treatments. Project two is related to knockdown of a specific protein that results in HCC in a different mouse model. The goal in the second project is to identify the genes and pathways that correlate with this protein.\\ \\ +

-  - Ron Walter's lab ran their pipeline to filter the fastq data. These files are stored in folder called Filtered_fastq_files. From Will Boswell: "PE stands for paired end reads. For example, you have a 500bp fragment and your target sequence size is 125bp. The fragment will be sequenced 125 bases from one end and 125 bases from the other end, and Illumina refers to this as paired end reads. SE stands for single end reads, which in our case is generated during our filtering process. If you look at the pre-filtered reads, you’ll see only PE1 and PE2 for each sample. During filtration, if one of the PE’s have low quality, it is tossed out leaving the other PE, and since it no longer has a mate pair, it’s kept as a single end sequence. Also, there are several files in the post-filtered directories that are considered intermediate files in the filtering process that we don’t need; these are process files used by the filtering script. The only files you should be concerned with are the _pe1.r.fastq, _pe2.r.fastq, _se.r.fastq, and _PE.filter.stats (gives you the number of reads mapped to the genome for each PE and SE)."
