â¢ AUTOIMMUNE DISEASE (noun). The noun AUTOIMMUNE DISEASE has 1 sense: 1. any of a large group of diseases characterized by abnormal functioning of the immune system that causes your immune system to produce antibodies against your own tissues.
The initiation of cell transformation is generally associated with genetic alterations in normal cells that lead to the loss of intercellular-and/or extracellular-matrix- (ECM-) mediated cell adhesion.ancer afflicts an organ or a tissue by inducing abnormal and uncontrolled division of cells that either constitute it or migrate to it. At the cellular level, this is caused by genetic alterations in networks that regulate cell division and cell death.
Mutation can result in several different types of change in sequences. Mutations in genes can either have no effect, alter the product of a gene, or prevent the gene from functioning properly or completely. DNA damage can cause an error when the DNA is replicated, and this error of replication can cause a gene mutation that, in turn, could cause a genetic disorder. DNA damages are repaired by the DNA repair system of the cell. Each cell has a number of pathways through which enzymes recognize and repair damages in DNA.
