Desmoplastic infantile ganglioglioma is a rare World Health Organization (WHO) grade I tumor commonly arising in early infancy and usually presenting with both solid and cystic components. We report a case of a large midline-enhancing desmoplastic infantile ganglioglioma in which newly formed cysts in communication with lateral ventricles contained highly(More)
Although obesity is a risk factor for development of type 2 diabetes and chemical modification of proteins by advanced glycoxidation and lipoxidation end products is implicated in the development of diabetic complications, little is known about the chemical modification of proteins in adipocytes or adipose tissue. In this study we show that(More)
While Burkitt lymphoma (BL) has a well-known defect in HLA class I-mediated antigen presentation, the exact role of BL-associated HLA class II in generating a poor CD4(+) T-cell response remains unresolved. Here, we found that BL cells are deficient in their ability to optimally stimulate CD4(+) T cells via the HLA class II pathway. This defect in CD4(+)(More)
The type 1 parathyroid hormone receptor (PTH1R) is a key regulator of calcium homeostasis and bone turnover. Here, we employed SILAC-based quantitative mass spectrometry and bioinformatic pathways analysis to examine global changes in protein phosphorylation following short-term stimulation of endogenously expressed PTH1R in osteoblastic cells in vitro.(More)
Connective tissue growth factor (CTGF, CCN2) is overexpressed in lung fibroblasts isolated from patients with interstitial lung disease (ILD) and systemic sclerosis (SSc, scleroderma) and is considered to be a molecular marker of fibrosis. To understand the significance of elevated CTGF, we investigated the changes in lung fibroblast proteome in response to(More)
In severe pressure overload-induced cardiac hypertrophy, a dense, stabilized microtubule network forms that interferes with cardiocyte contraction and microtubule-based transport. This is associated with persistent transcriptional up-regulation of cardiac alpha- and beta-tubulin and microtubule-stabilizing microtubule-associated protein 4 (MAP4). There is(More)
UBR5 (ubiquitin protein ligase E3 component n-recognin 5)/EDD (E3 ligase identified by differential display) is an E3 ubiquitin ligase that is a potential biomarker for poor prognosis for recurrent, platinum-resistant ovarian cancer. UBR5 has a role in the DNA damage response and many such proteins are regulated by phosphorylation. UBR5 is a 309 kDa nuclear(More)
BH3 interacting-domain death agonist (Bid) is a BH3-only pro-apoptotic member of the Bcl-2 family of proteins. Its function in apoptosis is associated with the proteolytic cleavage to the truncated form tBid, mainly by caspase-8. tBid translocates to mitochondria and assists Bax and Bak in induction of apoptosis. c-Jun N-terminal kinase (JNK)-dependent(More)

While the defects in HLA class I-mediated Ag presentation by Burkitt lymphoma (BL) have been well documented, CD4+ T-cells are also poorly stimulated by HLA class II Ag presentation, and the reasons underlying this defect(s) have not yet been fully resolved. Here, we show that BL cells are deficient in their ability to optimally stimulate CD4+ T cells via(More)
