RESUMEN

Changes in nuclear morphology are common in malignant tumors, but the underlying molecular mechanisms remain poorly understood. Lamins is involved in supporting nuclear structure, and the expression of Lamins is the molecular basis for nuclear morphological changes during tumor progression. In recent years, the research on the relationship between Lamins and malignant tumors has made great progress. Lamins is of great value in the diagnosis, treatment, and prognosis of various malignant tumors.

RESUMEN

Lamins are the major structural proteins of the nucleus in an animal cell. In addition to being essential for nuclear integrity and assembly, lamins are involved in the organization of nuclear processes such as DNA replication, transcription and repair. Mutations in the human lamin A gene lead to highly debilitating genetic disorders that primarily affect muscle, adipose, bone or neuronal tissues and also cause premature ageing syndromes. Mutant lamins alter nuclear integrity and hinder signalling pathways involved in muscle differentiation and adipocyte differentiation, suggesting tissue-specific roles for lamins. Furthermore, cells expressing mutant lamins are impaired in their response to DNA damaging agents. Recent reports indicate that certain lamin mutations act in a dominant negative manner to cause nuclear defects and cellular toxicity, and suggest a possible role for aberrant lamins in normal ageing processes.
