Asparagine Synthetase in Cancer: Beyond Acute Lymphoblastic Leukemia. Asparagine Synthetase (ASNS) catalyzes the synthesis of the non-essential amino acid asparagine (Asn) from aspartate (Asp) and glutamine (Gln). ASNS expression is highly regulated at the transcriptional level, being induced by both the Amino Acid Response (AAR) and the Unfolded.

Asparagine synthetase is a chiefly cytoplasmic enzyme that generates asparagine from aspartate. This amidation reaction is similar to that promoted by glutamine synthetase. The enzyme is ubiquitous in its distribution in mammalian organs, but basal expression is relatively low in tissues other than the exocrine pancreas. Above average presence of asparagine synthetase in certain leukemia strains has been linked to be a significant contributing factor of chemotherapy resistance. Asparagine synthetase is a predictive biomarker of L-asparaginase activity in ovarian cancer cell lines.

Asparagine synthetase forms filaments in yeast in response to nutrient limitation and is part of a pathway that is a chemotherapy target in acute lymphoblastic leukemia. Interestingly, while yeast asparagine synthetase forms cytoplasmic filaments in response to nutrient stress, human asparagine synthetase is associated with the centrosomes and mitotic spindles Asparagine synthetase (ASNS) was identified as a key node protein in these processes. Interestingly, knockdown of ASNS improved the antitumor potency of ART and 221 in vitro and in vivo, and treatments with ART and 221 disordered the amino acid metabolism of A549 cells L-Asparagine is an amino acid required for the synthesis of many important cellular proteins in normal human cells. Many tumor cells do not have this capacity, due a lack of the enzyme L-asparagine synthetase, and therefore require an exogenous supply of the amino acid The potential metabolic advantages of low and high expression of Asparagine Synthetase (ASNS) in cancer cells. (Left) Low ASNS expression, caused by promoter methylation, renders cells dependent on asparagine (Asn) uptake, while increasing aspartate (Asp) availability for the synthesis of nucleotides, other non-essential amino acids (NEAA), and energy production

In addition, we show that asparagine regulation of serine uptake influences serine metabolism and nucleotide synthesis, suggesting that asparagine is involved in coordinating protein and nucleotide synthesis. Finally, we show that maintenance of intracellular asparagine levels is critical for cancer cell growth After immunohistochemical confirmation of expressed proteins in 166 clinical tissues, asparagine synthetase (ASNS) and filamin A (FLNA) were selected for further functional study. Cisplatin-sensitive (CS; ASNShigh and FLNAlow) and cisplatin-resistant (CR; ASNSlow and FLNAhigh) SKOV3 and OVCAR3 ovarian cancer cell lines were used for subsequent in vitro and in vivo experiments Asparagine synthetase is a predictive biomarker of l-asparaginase activity in ovarian cancer cell lines.

In this study, we employed RNA interference as an efficient tool to silence endogenous ASNS expression in breast cancer cell lines

Asparagine synthetase (ASNS) 4 catalyzes the synthesis of asparagine and glutamate from aspartate and glutamine in an ATP-dependent amidotransferase reaction (Fig. 1A) ().The recent discovery of a neurologic disorder associated with asparagine synthetase deficiency (ASD) and its long recognized importance in the treatment of acute lymphoblastic leukemia (ALL) highlight the clinical relevance. Leukemia 5178 Y AR (resistant to l-asparaginase) contains l-asparagine synthetase (EC 6.3.5.4).As this neoplasm grows in the inguinal tissue of BDF 1 mice, it metastasizes widely. l-Asparagine synthetase has been found to increase in concentration in liver, spleen, kidney, and several other tissues as a concomitant of such metastasis.Treatment with l-asparaginase on the day prior to or the day. enzymes that have been implicated in cancer metabolism with an unusual subcellular localization.

Expression of human asparagine synthetase (ASNS) promotes metastatic progression and tumor cell invasiveness in colorectal and breast cancer, presumably by altering cellular levels of L-asparagine AbstractModern clinical treatments of childhood acute lymphoblastic leukemia (ALL) employ enzyme-based methods for depletion of blood asparagine in combination with standard chemotherapeutic agents. Significant side effects can arise in these protocols and, in many cases, patients develop drug-resistant forms of the disease that may be correlated.

Our bodies make asparagine, as well as many of the other amino acids that form proteins, and this is one of the enzymes that helps make it. Apparently, the more active this enzyme, the better breast cancer (in this mouse model) is able to spread. That's interesting

Asparagine Synthetase (ASNS) represents a single mammalian-expressed enzyme that catalyzes the synthesis of asparagine and glutamate from aspartate and glutamine in an ATP-dependent amidotransferase reaction (1). Interest in targeting asparagine metabolism in cancer is based on the observation that unlike most normal cells,. Asparagine synthetase deficiency (ASD) has been found to be caused by certain mutations in the gene encoding human asparagine synthetase (ASNS). Among reported mutations, A6E mutation showed the greatest reduction in ASNS abundance. However, the effect of A6E mutation has not yet been tested with yeast asparagine synthetase (Asn1/2p).

There are about 564,000 new cases of HCC each year throughout the world [].Recently, Zhang et al. reported that asparagine synthetase (ASNS) was an independent predictor of surgical survival and a potential therapeutic target in HCC [].Meanwhile, Wu et al. reported that HBsAg-negative healthy individuals and chronic hepatitis. In yeast, asparagine synthetase forms cytoplasmic structures and does not co-localize with microtubules. Previous screens of the yeast GFP strain collection found that yeast Asn1p and Asn2p can form cytoplasmic foci and filaments in response to nutrient limitation (Narayanaswamy et al., 2009; Shen et al., 2016).However, these studies did not address the possibility that the GFP tag might be.
