MetabolomicsIntegrated proteomic and metabolomic profiling reveals molecular signatures underlying invasiveness in non-functioning pituitary adenomas

Pituitary adenomas constitute 10 to 25% of intracranial tumors, rendering them one of the most prevalent types of brain tumors. While the majority of pituitary adenomas are benign, ~35% exhibit invasive behavior. Compared with their non-invasive counterparts, invasive pituitary adenomas are more ...

TranscriptomicsTranscription profiling of human pituitary adenomas
This series includes the four major subtypes of pituitary adenomas and normal post-mortem pituitary tissue; Data Transformation; Using Affymetrix Microarray Suite 5.0 global scaling was applied to the quantification data to adjust the average recorded to a target intensity of 100. Data were then exp...

ProteomicsQuantitative proteomics of non-invasive and invasive pituitary adenomas
We collected samples from patients with invasive and non-invasive pituitary adenomas from Beijing Tiantan Hospital for protein extraction and quantitative analysis, and identified invasive differential proteins (DEPs) by differential analysis of the two groups.

TranscriptomicsTranscriptome analysis of MENXM-bM-^@M-^Qassociated rat pituitary adenomas identifies novel molecular mechanisms involved in the pathogenesis of human pituitary gonadotroph adenomas
Gonadotroph adenomas comprise 15M-bM-^@M-^S40 % of all pituitary tumors, are usually non-functioning and are often large and invasive at presentation. Surgery is the first-choice treatment, but complete resection is not always achieved, leading to high recurrence rates. As gonadotroph adenomas poorl...

TranscriptomicsTranscription profiling of human invasive and non-invasive non-functioning pituitary adenomas
Context : Non Functioning Pituitary Adenomas (NFPAs), although typically benign, may be locally invasive. Few datas are currently available related to the molecular process of invasion in sporadic pituitary adenomas. Markers of invasiveness, important for helping the clinician in the therapeutic s...

ProteomicsUnderstanding early AutoAb signatures in Pituitary Adenomas using CDI HuProt™ (Human Proteome Microarray)
CDI HuProt™ (Human Proteome Microarray), was used to study Pituitary Adenomas PAs (Acromegaly, Cushing's and NFPA) using serum samples, from around 14 individuals (4 Healthy control, 4 Acromegaly, 3 Cushing’s and 3 NFPAs patient samples) were used study their autoantibody profiles. Patient serum sam...

TranscriptomicsTranscription profiling of gonadotrope pituitary tumors identifies Growth arrest and DNA-damage-inducible gene beta (GADD45beta) as a Novel Tumor Suppressor in Pituitary Gonadotrope Tumors
Gonadotrope or null cell pituitary tumors present clinically with signs of hypogonadism and hypopituitarism, together with visual disturbances due to mass effects. Since there are no medical therapies, surgery and/or radiation are the only therapeutic options. To identify dysregulated genes and/or...

TranscriptomicsPituitary tumors contain a side population with 'tumor stem cell'-associated characteristics [set 1]
Pituitary adenomas cause significant endocrine and mass-related morbidity. Not much is known about mechanisms underlying pituitary tumor pathogenesis.We searched for a side population (SP) in pituitary tumor, representing cells with high efflux capacity and potentially enriching for cancer/tumor ste...

TranscriptomicsmicroRNA profiling of female and male mouse pituitary gland across pubertal transition
The pituitary gland exhibits sex differences in its function. Diseases associated with dysregulation of the pituitary are also sex-biased in prevalence. Previous qPCR profiling of puberty-related genes in the pituitary gland revealed increasingly sex-biased expression of genes profiled across pubert...
