DESeq2 on multilevel design variable

Hello, I am working with RNA-seq data and using DESeq2 to perform differential expression analysis. My design has a single factor, diagnosis, which is a multi-level factor with six different diagnoses: ‘Craniopharyngioma’, ‘ATRT’, ‘Ependymoma’, ‘Glioblastoma’, ‘Glioma’, and ‘Medulloblastoma’. My design is as follows: dds <- DESeqDataSetFromMatrix(countData = count_data, colData =…

The secrets of the human genome: researchers uncover clues

Humans have only just scratched the surface when it comes to understanding our genome. The massive new Zoonomia project, however, has revealed the importance of studying the genomes of other mammals, such as bumblebee bats, cheetahs and hippos, in order to better understand our own. By comparing the DNA of…

Bats, Cheetahs and Hippos Unlock Mysteries of the Human Genome

Comment on this storyComment Humans like to think we have a monopoly on understanding ourselves — that explanations for all our inner workings, including when things go awry, lie within our genetic code. We might like to think that, but we’re wrong. Whether it’s the diminutive bumblebee bat, the lightning-fast cheetah…

How 240 Mammal Species Help Explain Human Disease Risks

A significant international study examining the genomes of 240 mammals has revealed over three million key regulatory elements, advancing understanding of mammalian evolution, species-specific traits, disease predispositions, and risk of extinction. The findings, which could improve understanding and treatment of diseases like schizophrenia, asthma, and medulloblastoma, underscore that at least…

Ambitious genome project shows how humans fit with other mammals

Scientists on Thursday unveiled the results of a project comparing the genomes of 240 mammal species – from aardvarks and aye-ayes to zebus and zebras, as well as people – to trace evolutionary changes spanning 100 million years, pinpointing genetic traits widely shared and those more uniquely human. The findings…

A Genomic Odyssey Across 240 Mammalian Species Explains Human Disease Risks and More

The Zoonomia Project has documented the genetic diversity in 240 mammalian species, covering over 80% of mammalian families. By sequencing and aligning the genomes, the team has identified conserved genomic regions across species, highlighting areas that may be biologically significant, but do not code for proteins. Their research suggests that…

ALT Plays Role in Treating CNS Tumors: CHOP Studies

Kristina A. Cole, MD, PhD Two recent papers from researchers in the Children’s Hospital of Philadelphia (CHOP) Cancer Center have advanced the understanding of treatment-resistant pediatric tumors, both in assessing a novel treatment and in characterizing the role of alternative lengthening of telomeres (ALT) in these refractory tumors. The first…

Fat-burning molecule may be promising target

FOR IMMEDIATE RELEASE Research from Johns Hopkins Kimmel Cancer Center experts revealed a type of RNA, previously considered to be “junk,”  that may help doctors distinguish and treat a subgroup of patients with medulloblastoma. Medulloblastoma is the most common malignant brain tumor in children, accounting for about 20% of all…

Specific stem cell protein found to be involved in the recurrence of medulloblastoma

The malignant brain tumor type medulloblastoma can become resistant to therapy which can cause relapse. Researchers at Uppsala University have discovered a certain protein that makes tumor cells resting and insensitive to radiation treatment. The research group hopes that the results could eventually lead to better treatments for children that…
