Lung cancer remains the leading cause of death due to cancer. We do not have effective tools for the early detection of lung cancer, so patients are usually diagnosed at an advanced stage. However, novel therapies based on molecular pathways (such as those involving the epidermal growth factor receptor, anaplastic lymphoma kinase, serine/threonine-protein kinase B-Raf, proto-oncogene tyrosine-p...

Medullary thyroid cancer accounts for 5-10% of thyroid carcinomas. RET proto-oncogene mutations occur in all of the hereditary MTCs and about 66% of the sporadic MTCs. So, the detection of the RET mutations is necessary for rapid and proper diagnosis and treatment. This systematic review seeks to find a comprehensive list of RET gene mutations in the diagnosis of medullary thyroid cancer. The ...

The BCL-6 proto-oncogene is involved in the genesis of non-Hodgkin lymphoma (NHL). Rearrangements due to chromosomal translocations and somatic mutations of the 5' noncoding regulatory region of the BCL-6 gene are potential mechanisms for altering its expression in NHL. To further elucidate the nature of the somatic mutations in the regulatory region of this gene, we have studied 10 healthy don...

Anaplastic large-cell lymphoma (ALCL) represents a morphologically distinct type of non-Hodgkin's lymphoma (NHL) characterized phenotypically by the expression of the CD30 antigen, a new member of the nerve growth factor gene family. The lymphoid origin of ALCL has been documented using immunohistochemical and molecular genetic analyses. However, very little is known so far regarding the precis...

Tumorigenesis, in general, is originated from two types of gene alterations, a tumor suppressor gene and a proto-oncogene/oncogene. A tumor suppressor gene, or anti-oncogene, is a gene that protects a cell from tumorigenesis. When this gene mutates, it causes a loss or reduction in its protection[1]. A proto-oncogene is a normal gene coding proteins which regulate cell growth and differentiatio...
