Poroelastic osmoregulation of living cell volume. [PDF]

iScience, 2021
Cells maintain their volume through fine intracellular osmolarity regulation. Osmotic challenges drive fluid into or out of cells causing swelling or shrinkage, respectively.

Determinants of anti-PD-1 response and resistance in clear cell renal cell carcinoma [PDF]

, 2021
ADAPTeR is a prospective, phase II study of nivolumab (anti-PD-1) in 15 treatment-naive patients (115 multiregion tumor samples) with metastatic clear cell renal cell carcinoma (ccRCC) aiming to understand the mechanism underpinning therapeutic response.

Effects of Endogenous Hormones and Sugars on Fruit Size Driven by Cell Division between Korla Fragrant Pear and Its Bud Mutation

HortScience, 2021
Large-fruit bud mutations are important factors in fruit tree breeding. However, little is known about the differences between varieties and bud mutations.

Cell AT-Models for Digital Volumes [PDF]

, 2009
In [4], given a binary 26-adjacency voxel-based digital volume V, the homological information (that related to n-dimensional holes: connected components, ”tunnels” and cavities) is extracted from a linear map (called homology gradient vector field) acting on a polyhedral cell complex P(V) homologically equivalent to V.

Ions, cell volume, and apoptosis [PDF]

Proceedings of the National Academy of Sciences, 2000
Programmed cell death culminating in apoptosis is responsible for normal tissue homeostasis and has increasingly been implicated in mediating pathological cell loss (1–3). Apoptosis is accompanied by characteristic morphological changes, including cell body and nuclear condensation, chromatin margination, and the formation of membrane-bound remnants ...

Micropatterning of single endothelial cell shape reveals a tight coupling between nuclear volume in G1 and proliferation [PDF]

, 2008
Shape-dependent local differentials in cell proliferation are considered to be a major driving mechanism of structuring processes in vivo, such as embryogenesis, wound healing, and angiogenesis.

Cell Migration with Multiple Pseudopodia: Temporal and Spatial Sensing Models [PDF]

, 2013
Cell migration triggered by pseudopodia (or “false feet”) is the most used method of locomotion. A 3D finite element model of a cell migrating over a 2D substrate is proposed, with a particular focus on the mechanical aspects of the biological phenomenon.

p57(Kip2) imposes the reserve stem cell state of gastric chief cells

, 2022
Adult stem cells constantly react to local changes to ensure tissue homeostasis. In the main body of the stomach, chief cells produce digestive enzymes; however, upon injury, they undergo rapid proliferation for prompt tissue regeneration.

Chemotaxis: a feedback-based computational model robustly predicts multiple aspects of real cell behaviour [PDF]

, 2011
The mechanism of eukaryotic chemotaxis remains unclear despite intensive study. The most frequently described mechanism acts through attractants causing actin polymerization, in turn leading to pseudopod formation and cell movement.

Timing the Landmark Events in the Evolution of Clear Cell Renal Cell Cancer: TRACERx Renal.

, 2022
Clear cell renal cell carcinoma (ccRCC) is characterized by near-universal loss of the short arm of chromosome 3, deleting several tumor suppressor genes. We analyzed whole genomes from 95 biopsies across 33 patients with clear cell renal cell carcinoma.
