It can be incorporated into pre-existing workflow pipelines and can rapidly analyze several samples at…
A team of researchers from the University of Chinese Academy of Sciences, China, and collaborators developed GeneCompass, one of the first foundation models of its kind that encompasses a vast expanse of knowledge across a diverse array of species, owing to the fact that it has been trained on over 120 million single-cell transcriptomes derived…
Researchers from the University of Pittsburgh, USA, have made a momentous breakthrough in the realm of single-cell sequencing with the creation of IndepthPathway, an innovative method for pathway enrichment analysis from scRNA-seq data. Overcoming the challenges posed by high noise and low gene coverage in single-cell sequencing, this tool employs the Weighted Concept Signature Enrichment Analysis…
Scientists from the Swiss Institute of Bioinformatics devise a workflow known as Single Cell Analysis mRNA Pipeline, ‘scAmpi,’ for providing complete functionality to scRNA-seq data analysis. In order to understand tissue composition at the single-cell level, to shed light on disease processes, tumor heterogeneity, and the condition of the immune milieu, single-cell RNA sequencing (scRNA-seq) has…
The emergence of single-cell RNA sequencing (scRNA-seq) has now made it possible to analyze the internal workings of hundreds of cells at once, revolutionizing biology and medicine. However, the limitations of scRNA-seq methods include the potential for inaccurate cell composition analysis and the ineffectiveness of complementary DNA (cDNA) amplification, which is the process by which…
Scientists from Whitehead Institute and collaborators used Perturb-seq, a single-cell sequencing technology, to link every expressed gene in the human genome to its function in the cell, offering a free resource for other researchers that can be accessed via the internet. The Human Genome Project was a huge undertaking that aimed to sequence every single…
Researchers from BGI-Research, in collaboration with scientific research teams from China, Germany, Italy, Singapore, Spain, Sweden, and the United Kingdom, published the world’s first non-human primate whole-body cell transcriptomic atlas in the scientific journal Nature this week, in a breakthrough that could lead to scientific advancement in the treatment of human diseases. The study will…
Scientists from the University of Queensland found, a bit of “junk DNA” could be the key to eradicating fear-related memories in persons suffering from post-traumatic stress disorder (PTSD) and phobia. While researching how the genome responds to traumatic experiences, an international research effort led by Associate Professor Dr. Timothy Bredy of the Queensland Brain Institute…
‘CellTrek’ can accurately map single cells in diverse tissue types to resolve their spatial organization. The tool identifies the location of particular cell types to drive biological insights. Scientists at The University of Texas MD Anderson Cancer Center have created a new computational methodology that successfully combines data from simultaneous gene-expression profiling approaches to build…
Scientists from the University of North Carolina School of Medicine, led by Scott Magness, Ph.D., sequenced the genes expressed in single cells from human digestive tracts to discover new cell-type characteristics and learn more about essential cell functions like nutrient absorption and immune defense. You could feel uneasy in your tummy if you get nervous….
Scientists from the Broad Institute of MIT and Harvard discovered an approach to studying the functional implications of the millions of mutations linked to cancer by pooling Perturb-seq and measuring the impact of TP53 and KRAS variants on RNA profiles in single cancer cells. Precision medicine entails predicting how specific genetic variants affect a patient’s…
