Abstract
The cytoskeletal pattern of the most superficial layers (cortex and epithelium) of senile cataractous lenses has been analyzed by PAGE-SDS. While the nuclear type of cataract and age-matched transparent human lenses have superimposable protein patterns, lenses with cortical cataract demonstrate appreciable modifications of their cytoskeletal composition. The most evident change is the decrease of fodrin and the marked reduction or even the absence of the 98 Kd band. Fodrin may be completely removed from the water insoluble fraction (WIF) of cortical cataract by extraction in low ionic strength buffer, a treatment which only partially solubilizes this protein in transparent control lensesI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
