Abstract

The physiological function of epithelia is transport of ions, nutrients, and fluid either in secretory or absorptive direction. All of these processes are closely related to cell volume changes, which are thus an integrated part of epithelial function. Transepithelial transport and cell volume regulation both rely on the spatially and temporally coordinated function of ion channels and transporters. In healthy epithelia, specific ion channels/transporters localize to the luminal and basolateral membranes, contributing to functional epithelial polarity. In pathophysiological processes such as cancer, transepithelial and cell volume regulatory ion transport are dys-regulated. Furthermore, epithelial architecture and coordinated ion transport function are lost, cell survival/death balance is altered, and new interactions with the stroma arise, all contributing to drug resistance. Since altered expression of ion transporters and channels is now recognized as one of the hallmarks of cancer, it is timely to consider this especially for epithelia. Epithelial cells are highly proliferative and epithelial cancers, carcinomas, account for about 90% of all cancers. In this review we will focus on ion transporters and channels with key physiological functions in epithelia and known roles in the development of cancer in these tissues. Their roles in cell survival, cell cycle progression, and development of drug resistance in epithelial cancers will be discussed.

  • Supra-physiological osmolarity can directly affect cell membrane tension and volume, but can also moderate how cells respond to other environmental parameters.

    “Supra-physiological osmolarity can directly affect cell membrane tension and volume (Pedersen et al., 2013), but can also moderate how cells respond to other environmental parameters (Dezengotita et al., 1998).”

    From Toward Best Practices for Controlling Mammalian Cell Culture Environments (2022) · cites this paper as Pedersen et al., 2013

    The 'Physiology of epithelial transport and role of cell volume' section says that altered extracellular osmolarity creates osmotic gradients and discusses associated changes in cell volume. It does not specifically address supra-physiological osmolarity or state that osmolarity directly changes cell membrane tension. The later clause about responses to other environmental parameters is attributed to Dezengotita et al., not to this source. (LLM, conf=0.82)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
