๐ป R packages for RNA-seq analysis
โจ Many have asked for this, so I am going to explain the purpose of each of these packages. DM me if you have any questions regarding this!
- GEOquery: to download RNA-seq files from SRA. This is just one way of downloading files. You may also use download.file() function in R if you have the ftp link to your data
- fastqcr: a wrapper to run FastQC in R. Current standard for running quality control
- QuasR: Trim and filter RAW sequencing reads
- RSubread: Align reads to the genome and quantify gene/transcript read counts
- DESeq2: Differential gene expression. Check my IGTV for a tutorial!

Year 1: Full of hair and hope
Year 3: Slight thinningโฆ maybe itโs the RNA-Seq
Year 7: Bald like the FASTA fileโno annotations, no hair.

I spend part of my afternoon putting some data through our RNA SEQ pipeline. I just didnโt some basic QC while referencing the project description form. I used DESEQ2 and r studio to do this:).

New to RNA-seq data? Donโt know how to code? First step should ALWAYS be quality checks on your raw reads. Follow this video on how to use FastQC on an internet browser with no coding experience needed #rnaseq #bioinformatics #phdjourney #gradschool #codingeducation
Let me show you how to do Single-Cell RNA-Seq Analysis for any cancer dataset. Here, Iโm executing single-cell RNA-seq pipeline on prostate cancer dataset. #scRNA #singlecell #rnaseq #ngs #python #linux #cancergenomics #genomics #biology #research

Yep, thatโs probably a t-SNE plot โ one of the most popular ways to visualize single-cell RNA-seq data.

๐ฏ Single-cell RNA-seq gives us massive data โ each cell is basically a mini spreadsheet of gene expression.
๐ง Our brains canโt visualize 20,000 dimensions โ so we need something to reduce it to 2D or 3D.
Thatโs where ๐ญ-๐๐๐ (๐ญ-๐๐ข๐ฌ๐ญ๐ซ๐ข๐๐ฎ๐ญ๐๐ ๐๐ญ๐จ๐๐ก๐๐ฌ๐ญ๐ข๐ ๐๐๐ข๐ ๐ก๐๐จ๐ซ ๐๐ฆ๐๐๐๐๐ข๐ง๐ ) steps in.
Think of t-SNE like this: It takes cells that are similar, based on their gene expression, and puts them close together in the plot.

๐ก The result? You get a plot that looks like art but actually reflects meaningful biological patterns โ like cell types, disease states, or treatment response.

A chill scientistโs weekday ft RNA-seq prep
One of my goals during my PhD is to create a comprehensive single nuclear RNA-seq dataset for human abdominal aneurysms compared to healthy aortas. Not necessarily part of my thesis, but I thought itโd be great to experience the data prep part as Iโve mostly been doing computational analysis of these types of data. I am extremely lucky to have a lab that can fund this experience and have access to clinical samples from the hospital!
We top off the day with a bunch of cell culture. I am culturing smooth muscle, endothelial cells, and THP1 monocytes. These are for larger experiments where I have these cell types try to eat/phagocytose apoptosis versions of each other (efferocytosis assay). Needs lots of cells for these and need to stain to track well for flow.
We top it off with a 2.4K swim featuring sets containing longer endurance sets and small 50m repeating interval for speed. It was great :)
Time to do it all over again tomorrow.
