Pituitary tumors are relatively common intracellular neoplasms, and constitute 10-15% of all intracial neoplasms. These types often have difficulties not infrequent recurrence, even though surgery has been done. Although there many studies on pituitary tumors, the pathogenesis occurrence these is entirely clear. It generally considered that neoplasms primary tumors. Biomolecular electrons show ...

Pituitary tumors are common in the general population. Since neuroimaging techniques have improved, pituitary tumors are more often diagnosed incidentally. About 16.7% of the general population show changes in the pituitary gland. Predominantly, pituitary tumors are benign pituitary adenomas. Pituitary carcinomas or aggressive pituitary tumors are extremely rare. They might develop from benign ...

The aim of the study was to investigate the expression and clinical significance of early growth response protein 1 (EGR-1) and phosphatase and tensin homolog (PTEN) in the pituitary tumors of elderly patients. From January 2014 to December 2015, we collected 25 patient cases with non-invasive pituitary tumors, 10 cases with invasive pituitary tumors and 35 cases with healthy pituitary tissues ...

Pituitary tumors are rare in childhood and adolescence, with a reported prevalence of up to 1 per million children. Only 2-6% of surgically treated pituitary tumors occur in children, with some variation attributed to a lack of consensus for a pediatric age range and whether age at surgery or age at onset of symptoms was used. Although pituitary tumors in children are almost never malignant and...

Pituitary tumors develop at a high frequency in retinoblastoma (Rb)-knockout mice; however, defects in the Rb gene are not common in human pituitary tumors. The inverse correlation of Rb and p16 defects in certain human tumors has led us to investigate the expression of p16 in human pituitary tumors as an indirect mechanism of Rb inactivation. By Western blot analysis, the p16 gene product was ...
