Sialylation is modulated through maturation in hemocytes from Macrobrachium rosenbergii

Alteration of the sialylation pattern of the murine tooth germ after ethanol exposure

“…This recognition determines the inter-and extracellular interactions. Our results agree with those of previous studies (Sierra et al, 2001;Cerna et al, 2002) in which changes in the expression of specific sialic acids during cellular differentiation were shown to be good markers for determining the degree of cell maturation. Our results suggest that higher ethanol concentrations affect the sialylation pattern and that these concentrations may be associated with changes in tooth-germ cellular proliferation and differentiation in mice.…”

“…Likewise, sialic acids determine the intercellular communication and cell-to-extracellular matrix interactions. Changes in the expression of specific sialic acids during differentiation may be useful markers for the degree of cell maturation (Sierra et al, 2001;Cerna et al, 2002). Changes in glycosylation have been observed in some congenital diseases (Aebi and Hennet, 2001;Martin-Rendon and Blake, 2003) and pathological processes, such as Alzheimer disease (Guevara et al, 1998), prion protein disease (Rudd et al, 2002), and cancer (Dennis et al, 1999).…”

Protein Sialylation by Sialyltransferase Involves Radiation Resistance

“…Changes in the expression of specific sialic acids during differentiation may be useful markers for the degree of cell maturation (28,29). In particular, changes in glycosylation have been observed in some congenital diseases (30)(31)(32) and pathologic processes, such as Alzheimer's disease (33), prion protein disease (34), and cancer (35).…”

Dietary administration of bovine lactoferrin influences the immune ability of the giant freshwater prawn Macrobrachium rosenbergii (de Man) and its resistance against Aeromonas hydrophila infection and nitrite stress

“…In crustaceans, circulating haemocytes are involved in the production of melanin via the prophenoloxidase (proPO) system, which plays an important role in the defence reaction [10,11]. Based upon the recent classification of M. rosenbergii haemocytes [12], large ovoid haemocytes and undifferentiated round haemocytes might be carrying out the functions of the proPO system, like semigranular and granular haemocytes in other crustaceans [10]. Conversion of proPO to PO is through proPO activating enzyme (ppA), a serine protease [11].…”
