    • Evolutionary conservation of human ketodeoxynonulosonic acid production is independent of sialoglycan biosynthesis 

      Kawanishi, Kunio; Saha, Sudeshna; Diaz, Sandra; Vaill, Michael; Sasmal, Aniruddha; Siddiqui, Shoib S; Choudhury, Biswa P; Sharma, Kumar; Chen, Xi; Schoenhofen, Ian C; Sato, Chihiro; Kitajima, Ken; Freeze, Hudson H; Münster-Kühnel, Anja; Varki, Ajit (2021-03-01)
      Human metabolic incorporation of nonhuman sialic acid (Sia) N-glycolylneuraminic acid into endogenous glycans generates inflammation via preexisting antibodies, which likely contributes to red meat-induced atherosclerosis ...

    • Lysophosphatidic acid protects mesenchymal stem cells against hypoxia and serum deprivation-induced apoptosis 

      Chen, Jinghai; Baydoun, A. R.; Xu, Ruixia; Deng, Linzi; Liu, Xuebin; Zhu, Weiquan; Shi, Linhui; Cong, Xiangfeng; Hu, Shengshou; Chen, Xi (2008-01)
      Bone marrow-derived mesenchymal stem cells (MSCs) have shown great promise for cardiac repair. However, poor viability of transplanted MSCs within the ischemic heart has limited their therapeutic potential. Our previous ...

    • Sialoglycan recognition is a common connection linking acidosis, zinc, and HMGB1 in sepsis 

      Siddiqui, Shoib S; Dhar, Chirag; Sundaramurthy, Venkatasubramaniam; Sasmal, Aniruddha; Yu, Hai; Bandala-Sanchez, Esther; Li, Miaomiao; Zhang, Xiaoxiao; Chen, Xi; Harrison, Leonard C; Xu, Ding; Varki, Ajit (2021-03-09)
      Blood pH is tightly maintained between 7.35 and 7.45, and acidosis (pH <7.3) indicates poor prognosis in sepsis, wherein lactic acid from anoxic tissues overwhelms the buffering capacity of blood. Poor sepsis prognosis is ...

    • Studies on the Detection, Expression, Glycosylation, Dimerization, and Ligand Binding Properties of Mouse Siglec-E 

      Siddiqui, Shoib; Schwarz, Flavio; Springer, Stevan; Khedri, Zahra; Yu, Hai; Deng, Lingquan; Verhagen, Andrea; Naito-Matsui, Yuko; Jiang, Weiping; Kim, Daniel; Zhou, Jie; Ding, Beibei; Chen, Xi; Varki, Nissi; Varki, Ajit (2017-01-20)
      CD33-related Siglecs are a family of proteins widely expressed on innate immune cells. Binding of sialylated glycans or other ligands triggers signals that inhibit or activate inflammation. Immunomodulation by Siglecs has ...
