Dissecting the Mechanism of DNA Methylation on the Invasiveness of Pituitary Tumors.

Study Purpose

DNA methylation is one of the important ways of protein post-translational modification.Pituitary adenoma (PA) is a benign neuroendocrine tumor that originates from adenohypophysial 45 cells, and accounts for 10%-20% of all primary intracranial tumors. However some PAs can present with high invasiveness and irregular growth, which tend to compresses the optic chiasm and third ventricle, encase the internal carotid artery, and affect hormone secretion from the pituitary gland and hypothalamus. In this study we focus on the mechanism of DNA methylation on the invasiveness of pituitary tumors.

Recruitment Criteria

Accepts Healthy Volunteers Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms	No
Study Type An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes. An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes. Searching Both is inclusive of interventional and observational studies.	Observational
Eligible Ages	N/A and Over
Gender	All

More Inclusion & Exclusion Criteria

Inclusion Criteria:

- 1) histologically confirmed PAs, 2) Non-function pituitary adenomas.

Exclusion Criteria:

- 1) Associated with other tumors or serious underlying diseases, 2) the medical records were not complete, or the follow-up data were missing.

Trial Details

Trial ID: This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.	NCT05634655
Phase Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans. Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data. Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs. Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
