Dysmorphic nuclei are commonly seen in cancers and provide strong motivation for
studying the main structural proteins of nuclei, the lamins, in cancer. Past
studies have also demonstrated the significance of microenvironment mechanics to
cancer progression, which is extremely interesting because the lamina was
recently shown to be mechanosensitive. Here, we review current knowledge relating
cancer progression to lamina biophysics. Lamin levels can constrain cancer cell
migration in 3D and thereby impede tumor growth, and lamins can also protect a
cancer cell's genome. In addition, lamins can influence transcriptional
regulators (RAR, SRF, YAP/TAZ) and chromosome conformation in lamina associated
domains. Further investigation of the roles for lamins in cancer and even DNA
damage may lead to new therapies or at least to a clearer understanding of lamins
as bio-markers in cancer progression.
