OBJECTIVE
Plasma arginine (ARG) levels are reduced in breast cancer, suggesting diminished systemic ARG availability. ARG and its product nitric oxide (NO) are important in early postoperative recovery due to its roles in immune function and wound healing. It remains unclear whether major surgery
Luminal A (hormone receptor-positive) breast cancer constitutes 70% of total breast cancer patients. In an attempt to develop a targeted therapeutic for this cancer indication, we have identified and characterized Glial cell line-Derived Neurotrophic Factor (GDNF) Family Receptor Alpha 1 (GFRA1)
Nitric oxide (NO) is generated by a family of isoenzymes named nitric oxide synthases (NOS) which includes a cytokine-inducible form, NOSII. NO is a free radical known to inhibit cell proliferation, to induce apoptosis, and to be a mediator of macrophage cytostatic and cytotoxic effects. We
OBJECTIVE
Several studies have shown an overexpression of cyclooxygenase-2 (COX-2) and elevated levels of prostacyclin (PGI(2)) and thromboxane (TXA(2)) in colon cancer. In this report, we determined the distribution of inducible form of nitric oxide synthase (iNOS), PGI(2), and TXA(2) in cancerous
Estrogen-negative (ER-) breast cancer, is recognized as an aggressive subtype, more difficult to treat, with poor survival and prognosis. They are hormonally unresponsive, with no readily effective and specific target therapy. We have previously identified Nw-hydroxy L-Arginine
This study comparatively evaluated free amino acid pool formation in patients with T1-3N0-2M0 breast cancer treated with the drug Ukrain (25 patients, i.v. 100 mg/course) in combination with preoperative radiation or neoadjuvant therapies (25 subjects, total dose 20 Gy). All the patients underwent
Arginine depletion strategies, such as pegylated recombinant arginine deiminase (ADI-PEG20), offer a promising anticancer treatment. Many tumor cells have suppressed expression of a key enzyme, argininosuccinate synthetase 1 (ASS1), which converts citrulline to arginine. These tumor cells become
BACKGROUND
Peptidylarginine deiminase (PAD) post-translationally converts arginine residues to citrulline residues. Recent studies have suggested that PADI2 (PAD isoform 2), a member of the PAD family, is involved in the tumorigenic process of some tumors, especially breast cancer. However, little
Glembatumumab vedotin (CR-011-vc-MMAE) is a mAb-drug conjugate being developed by Celldex Therapeutics Inc for the treatment of glycoprotein non-metastatic melanoma protein B (GPNMB)-expressing cancers. Glembatumumab is a fully human mAb directed against an extracellular domain of GPNMB expressed in
Peptidylarginine deiminase IV (PADI4) catalyzes the conversion of positively charged arginine and methylarginine residues to neutrally charged citrulline, and this activity has been linked to the repression of a limited number of target genes. To broaden our knowledge of the regulatory potential of
Peptidyl arginine deiminase 4 (PAD4/PADI4) is a posttranslational modification enzyme that converts protein arginine or mono-methylarginine to citrulline. The PAD4-mediated hypercitrullination reaction in neutrophils causes the release of nuclear chromatin to form a chromatin network termed
BACKGROUND
Oxidative/nitrosative stress and endothelial dysfunction are hypothesized to be central to cancer therapeutics-related cardiac dysfunction (CTRCD). However, the relationship between circulating arginine-nitric oxide (NO) metabolites and CTRCD remains unstudied.
OBJECTIVE
This study sought
Peptidylarginine deiminase 4 (PAD4) is a Ca(2+)-dependent enzyme that converts arginine and methylarginine residues to citrulline, with histone proteins being among its best-described substrates to date. However, the biological function of this posttranslational modification, either in histones or
The peptidylarginine deiminase (PAD) family of enzymes post-translationally convert positively charged arginine residues in substrate proteins to the neutral, non-standard residue citrulline. PAD family members 1, 2, 3, and 6 have previously been localized to the cell cytoplasm and, thus, their
Targeted therapy using specific monoclonal antibodies (mAbs) conjugated to chemotherapeutic agents or toxins has become one of the top priorities in cancer therapy. Antibody-drug conjugates (ADCs) are emerging as a promising strategy for cancer-targeted therapy. In this study, trastuzumab, a
