  • Multifactor Integration into single seuratobject or multiple seuratobjects? (single cell RNAseq)

    Hello,

    I am doing single cell RNA-seq analysis. I have 2 groups of samples: Test and WT. For both groups, I have 2 different data: treated and untreated. My samples are a composition of various cell types, but each of my samples have the same variety of cell types (The samples are taken from the same tissue, so each sample has same composition. But they consist of various cell types, it is not cell-line.)

    I want to compare:
    untreated WT vs treated WT
    untreated WT vs untreated Test
    untreated Test vs treated Test
    treated WT vs treated Test​

    My question is, is it a good idea to do the analysis of the data in the same seuratobject? For example, by using multifactor integration into a single seuratobject? Or should I make separate seuratobjects for the variables?

    I am worried that the clustering and DEGs will get affected if I include everything into a single seuratobject. (I want the clustering to be by cell types) But the DEGs will probably be different before/after treatment.

    Thank you

    Essential Discoveries and Tools in Epitranscriptomics
    by seqadmin




    The field of epigenetics has traditionally concentrated more on DNA and how changes like methylation and phosphorylation of histones impact gene expression and regulation. However, our increased understanding of RNA modifications and their importance in cellular processes has led to a rise in epitranscriptomics research. “Epitranscriptomics brings together the concepts of epigenetics and gene expression,” explained Adrien Leger, PhD, Principal Research Scientist...

    Current Approaches to Protein Sequencing
    by seqadmin


    Proteins are often described as the workhorses of the cell, and identifying their sequences is key to understanding their role in biological processes and disease. Currently, the most common technique used to determine protein sequences is mass spectrometry. While still a valuable tool, mass spectrometry faces several limitations and requires a highly experienced scientist familiar with the equipment to operate it. Additionally, other proteomic methods, like affinity assays, are constrained...
