چکیده

Aneuploidy or alteration in chromosome numbers is a characteristic feature in cancer that is generally a consequence of defective chromosome segregation during cell division. Molecular cytogenetic analyses have conferred substantial evidence with regards to the chromosomal architectures in cancer. Most importantly, the fluorescence in situ hybridization (FISH) technique that plays a leading role in diagnostic pathology for its single-cell analysis has provided crucial information regarding genomic variations in malignant cells. Further development of molecular cytogenetic methodologies such as chromosome specific FISH karyotyping and comparative genomic hybridization have also helped in the detection of cryptic genetic changes in cancer. But, the recent advancement of high throughput sequencing technologies have provided a more comprehensive genomic analyses resulting in novel chromosome rearrangements, somatic mutations as well as identification of fusion genes leading to new therapeutic targets. This review highlights the application of early molecular cytogenetics and the recent high throughput genomic approaches in characterizing various cancers and their invaluable support in cancer therapeutics.

Targeted Cancer Diagnostic and Therapeutic Agents: Delivery by Carriers or Conjugation

Receptors and proteins are overexpressed in many human cancer cell membranes rather than normal tissues and are considered as the main molecular targets. Specific tumor- targeting molecules which have high affinity for these receptors can be valuable tools as carrier molecules for targeted cancer therapy and imaging. Pharmacokinetics and bioavailability of diagnostic and therapeutic agents are ...

An Overview of Technological Developments in Medical Applications of X-Rays and Radioactivity

The years 1895 to 1898 were momentous for their impact on health and human well beings. First, Wilhelm Roentgen noted a glowing fluorescent screen, caused by invisible rays. This event subsequently led to the discovery of X-rays in 1895, and thus the birth of the “atomic age”. Next Becquerel’s investigations of these mysterious rays led to his experiments with uranium salt crystals. He th...
