Mitochondria are essential to our overall health and well-being. In addition to producing energy, they regulate many critical processes in the body. (1/11) #mitochondria #energy #health
Mitochondria play a key role in the production and regulation of neurotransmitters. They also help produce key hormones like cortisol, estrogen, and testosterone. (2/11) #mitochondria #hormones #neurotransmitters #neurotwitter
Mitochondria are involved in epigenetics, which is the expression of #genes from the nucleus. They send signals to the nucleus that turn genes on or off. (3/11) #epigenetics #genes #mitochondria
Ageing: an inevitable part of life. Right? Perhaps not! Recent research from @Harvardmed (10.1016/j.cell.2022.12.027) suggests that ageing may be reversible. This exciting new research may help us better understand ageing! Thread→

Ageing is a gradual process which occurs at the cellular level in all living things. In humans, this is marked by physical and mental deterioration. Ageing also increases the risk of nearly all diseases. Though thanks to @davidasinclair, there is hope 👏(1/9).
Research published last month in @CellCellPress looked at the cause and potential solutions to ageing. One primary cause of ageing occurs in DNA, though not in the genes themselves (because that would be far too easy!). The changes actually occur at the epigenetic level (2/9).
1/@GraphiteBio presented preclinical results supporting the use of a single-#cell #RNA #sequencing method to assess #gene correction outcomes in #patients treated with nulabeglogene autogedtemcel (nula-cel) - GPH-101. #BioTech #CRISPR #GeneEditing #Genomics $GRPH #ASH22
2/GPH101 (nula-cel) is a #CRISPR #Cas9 #GeneEditing autologous #stem #cell-based #therapy in clinical development aimed to treat #SickleCellDisease. GPH101 is designed to directly correct the underlying mutation, thereby decreasing HbS production & restoring HbA expression #ASH22
3 $GRPH gene correction platform involves editing hematopoietic #stem cells found in the #bonemarrow that develop into various types of #blood #cells. Since red blood cells lose their genomic DNA during maturation-tracking #GeneEditing in mature cells via sequencing is impossible
Are you interested in learning about #bioinformatics and working with #genomic data? Here's a detailed #learning path to get you started:
To build a strong foundation in biology, you'll need to learn about:
The #structure and #function of #cells, including the various #organelles and their roles in the cell. This will help you understand how cells work and how they carry out essential functions such as #metabolism and #energy production.
"Best practices for single-cell histone modification analysis" w/ @VallotCeline @jeanphi_vert and @PPrompsy.
We identify how to analyze scCUT&Tag, from matrix construction, QC, #cells, up to dimension reduction.

@VallotCeline @jeanphi_vert @PPrompsy We use multiomics assays to evaluate the quality of the representation in a completely unsupervised fashion, by using the kNN-AUC between the two modalities (see openproblems.bio/benchmarks/mul…)
We further look at the 5 most common histone marks on human PBMC and mouse brain data.

@VallotCeline @jeanphi_vert @PPrompsy We show that similarly to scATAC-seq, LSI-based methods such as Signac and ChromSCape tend to outperform their competitors.
We further show that enhancing marks (H3K4me1 and H3K27ac) have extremely high agreement with expression data.

How precise are noisy #morphogen gradients in #tissue #patterning?
It turns out that the positional information they convey to #cells in the #neuraltube is much more accurate than previously estimated!

A methodological subtlety has previously led to overestimated positional errors of the morphogen gradients in the mouse neural tube. We reanalysed the noisy gradients and found that the positional information they can convey to cells is actually orders of magnitude more precise.
Also, morphogen gradients in differently sized tissues must not be pooled and rescaled to their mean length, or else an artificial positional error is added.

How do the hundreds of genetic risk-factors for #Schizophrenia actually lead to disease? New work medrxiv.org/content/10.110… from @manoliskellis illuminates the #SingleCell landscape of #Brains from patients with #Schizophrenia and their healthy counterparts🔬🧠🧵1/10
Combining single-nuclear RNA-Seq @10xGenomics, barcode #ing, and multi-level cell-state decomposition, first author Brad Ruzicka et al. identify 20 cell types in the prefrontal cortex of 24 patients with #Schizophrenia and 24 controls 2/10
While most of these #cells have been described before, what's powerful about the approach is that we can now ask: are there specific cell-types that are increased or decreased in numbers in #Schizophrenia patients compared to healthy individuals (great study design) 3/10
