This might be a bit long, please bare with me. I’m conducting a differential expression analysis using limma – voom. My comparison is regarding response vs non-response to a cancer drug. However, I’m not getting any DE genes, absolute zeros. Someone here once recommended not to use contrast matrix for…

Problem in getting SNAI1 gene in prostate DEG table 0 Hello everyone, would you please help me I have got prostate DEGs by TCGAbiolinks package but I couldn’t get SNAI1 gene in my DEG table. I wonder why it does happen. First I normalized it and then I filtered it,…

Outcome of DNA sequencing, assembly, and validation In this study, initially total DNA was isolated from the finely chopped, full-grown pupa of Blepharipa sp. The NanoDrop spectrophotometer (1294 ng/μl) and the Qubit fluorometer (732.8 ng/μl) both found that the concentration of total DNA in the sample at an optimum level for mitochondrial DNA enrichment. The Tape Station profile showed…

Extremely different results for both EdgeR and DESeq2 analysis 1 @373f98d7 Last seen 23 hours ago Singapore Dear all, Upon comparing my results for the analysis between DESeq2 and EdgeR, I have realized that the 2 results obtained after DEG analysis are extremely different from each other. The thresholds I…

Condition shown as ‘Untreated vs. Treated’ in output of results() in DESeq2 1 @bffcbc5f Last seen 16 hours ago United States of America I am trying to find differentially expressed genes using DESeq2 on some RNA-seq data. In the pheno data, there is a column named ‘condition’ with factored values…

I am trying to run the Monocle3 function find_gene_modules() on a cell_data_set (cds) but am getting a variety of errors in this. I have not had any other issues before this. I am working with an imported Seurat object. My first error came back stating that the number of rows…

DataViz question for DEG and scRNA-seq 1 Maybe a dumb question, but I recently came across a single-cell paper that showed “volcano” plots for all clusters in one image by filtering for all genes that were FDR <0.05, the x-axis being represented by different colors characterizing different clusters, the y-axis…

With long reproductive timescales, large complex genomes, and a lack of reliable reference genomes, understanding gene function in conifers is extremely challenging. Consequently, our understanding of which genetic factors influence the development of reproductive structures (cones) in monoecious conifers remains limited. Genes with inferred roles in conifer reproduction have mostly…

INTRODUCTION Mammalian life starts with the fusion of two terminally differentiated gametes, sperm and oocyte, resulting in a totipotent zygote. After going through preimplantation development, the zygote reaches blastocyst before implantation. The two most important events taking place during preimplantation development are zygotic genome activation (ZGA) and the first cell…

Introduction Thyroid carcinoma (THCA) is the most common type of endocrine malignancy and its incidence is increasing.1 Based on its histopathological characteristics, thyroid carcinoma can be classified into multiple subtypes, such as papillary thyroid carcinoma (PTC), follicular thyroid carcinoma, and anaplastic thyroid carcinoma.2 PTC is the most common subtype of…

Hi guys, I hope you are fine. I’m not good in English so if you couldn’t understand my question, please feel free to reply. I’m a beginner of bioinformatics. I want to practice differential expressed gene (DEG) analysis in R. The RNA seq data I used was downloaded from broad…

Enter the body of text here Hi, I am analysing a RNA Seq dataset coming from 3 independent cell isolates (isolate1, isolate2, isolate3), each given 3 different treatments (control, drug1, drug2). We are testing drug 1 against control in the first instance: We also observed that there is some variation…

How to generate a Venn diagram from edgeR DEG results? 0 Dear All, I have done DEG analysis of genes from 4 samples using edgeR. I want to plot them (number of DEGs) using a Venn diagram. I have results from pairwise comparisons as UP and DOWN gene list with…

Sorry for lateness, I wanted to do something similar. This is what I did for reference: Using a Seurat generated gene list for input into ClusterProfiler to see the GO or KEGG terms per cluster. I’ll keep the meat and potatoes of the Seurat vignette in this tutorial: library(dplyr) library(Seurat)…
