Cytological and cytogenetical studies on brain tumors
Tóm tắt
In the cytogenetical investigation of 70 meningiomas 5 tumors with a Ph1-like chromosome were found. In 3 tumors with 46 chromosomes this chromosome was identified to be indeed a deleted G chromosome. In the other 2 tumors the observed fragment could only be supposed to derive from a G chromosome, for further chromosomes were missing. The similarity of these findings to those in the chronic myelogenous leukemia enhances the hypothesis that the distal part of the long arm of one G chromosome influences the control of cell proliferation.
