Although our findings emphasize mainly lamin B1 rather than lamin A/C, this does not contradict previous findings on the roles of lamin A/C in confined migration[22] or the loss of lamin B1 in promoting lung cancer metastasis.[44] Our findings highlight that the function of different lamin subtypes in different stages of cancer progression is context‐dependent. The gene discussed is LMNB1; the disease is cancer.
