Effects of circ_0002375 on cisplatin-resistant NPC cells: After cisplatin treatment, circ_0002375 knockdown was transfected into cisplatin-resistant SUNE1/5-8F cells, which led to the inhibition of cisplatin resistance via down-regulating EIF5A2 that mediated by up-regulated miR-577.
The aim is to establish condensate biology as a fundamental branch of cellbiology – “cellbiology 2.0” The underlying biology and processes upon which the company was founded have broad applicability across various human disease areas. Klein notes the importance of Dewpoint’s disease-agnostic approach.
When I was studying cellbiology, looking at how cells divide, I couldn’t fathom how math could possibly fit into that. My undergraduate studies focused on biochemistry and cellbiology, so very much STEM-based, but my professors and mentors noticed my penchant for critical thinking which led me to consider law.
Metastasis is the most lethal attribute of cancer cells and clinical decisions regarding treatment are based largely upon the likelihood of developing metastases. 1 The research, supported by the National Institutes of Health, centres on a cellular chaperone protein called GRP78, responsible for regulating protein folding within cells.
This major shift to the orthodox tradition of using animal experiments in drug testing dates back the Aristotle’s time and cemented 80 years ago with initial federal mandate of drug safety regulation of 1938. From 3D cell culture to organs-on-chips. Trends in CellBiology. 2010;328(5986):1662-8. 2011;21(12):745-54.
Shear forces induce ICAM-1 nanoclustering on endothelial cells that impact on T-cell migration. Current Opinion in CellBiology. CAR T-cell entry into tumor islets is a two-step process dependent on IFNγ and ICAM-1. Cell adhesion molecules and their roles and regulation in the immune and tumor microenvironment.
This kind of regulation in AC activity is a kind of cellular adaptation in to the activation of opioid receptors and contributes to the development of opioid tolerance, dependence, and withdrawal 5. To facilitate MOR to transform to such a conformation is one of the strategies to induce MOR endocytosis.
Collagen density regulates the activity of tumor-infiltrating T cells
Kuczek, D.E., Particularly in TNBC, collagen remodeling is seen in the stromal compartment [ 3 ]. Assessing Collagen Features at a Finer Level of Detail. References.
Larsen, A.M.H., Thorseth, ML. immunotherapy cancer 7, 68 (2019).
Effectors of signal transmission events Second messengers are small molecules or ions that transmit signals received at the cell surface to the inside environment of the cell (Fig.
That includes those involved in regulating our appetites and our moods, via a class of G proteins known as inhibitory G proteins (G i ). They share a common architecture and bind a relatively limited number of intracellular signaling proteins called G proteins.
14 As an unbiased method for genetic variant detection, GWAS holds the promise of identifying new genes and gene regulation mechanisms underlying a variety of conditions, including complex diseases. Network expansion of genetic associations defines a pleiotropy map of human cellbiology. 53 , 1527–1533 (2021).
As such, it has been proposed that inhibiting CDK7 would provide a potent means of inhibiting cell cycle progression, which may be especially relevant given that there is compelling evidence from gene knockout studies in mice for lack of an absolute requirement for CDK2, CDK4 and CDK6 for the cell cycle at least in most cell types (M alumbres et al.,
It set a precedent with regulators as to what is expected in some instances. Because we are using cells as medicines, they’re living medicines that we hope that they become cancer treatments where it’s literally one dose and you’re done.
Our pilot study will span: 1) high-resolution EM (electron microscopy) of synaptic excitatory-inhibitory (E-I) balance and nearby glial cells; 2) functional electrophysiological signatures of altered E-I balance by sex in ACC brain slices; 3) molecular correlates of these impairments that can be targeted for recovery of function.
mRNA biology has become widely recognised as a new “drug mine” RNAi drugs are in the market and mRNA vaccines, initially developed for Covid-19, are already in trials for cancer. There must be something different in those diseased cells, some dysregulated pathway that is causing that disease phenotype.
Cell metabolism and disease Metabolic perturbations and metabolic reprogramming are associated with common human diseases. In fact, metabolism should not be considered as a self-regulating entity that is independent of other biological pathways. On the contrary, cell metabolism affects or is affected by a multitude of processes.

I then took over management of a research group, initially running cellbiology research and then preclinical development.” “Scientists now better understand how gene expression is regulated, leading directly to the development of ASOs that can target specific mutated genes,” Williams adds.

said study senior author Brad Bernstein , an institute member at Broad and director of the Gene Regulation Observatory at Broad. “We We found that IDH mutations are like a ticking time bomb that allows brain tumor cells to grow slowly and hide from the immune system while they acquire more dangerous mutations. Nature Cancer.
Post-translational modification of proteins, which includes the alteration of certain amino acid side chains by the introduction of different chemical groups, takes place in eukaryotic and prokaryotic cells. For example, it may result in changes to cell metabolism or lead to alterations in crucial signaling events.
Learnings regarding immune geography and cell:cell contact are increasingly important as we consider how best to advance cell therapies for diverse hematologic malignancies and solid tumors ( www.aletabio.com ). The immune system is tightly regulated and unkind to inappropriate signals. Fc-hacking immune responses.

Molecular biology has only been around for about 80 years, and tools to study biomolecules (such as DNA and RNA sequencing, or proteomics) have only existed for about half of that time. We are in the absolute infancy of molecular and cellbiology, and this means there’s a lot of stuff we still don’t understand.
