Abstract

We have studied the effects of human alpha-fetoprotein (HAFP), isolated from the serum and ascitic fluid of a hepatoma-bearing patient, on the in vitro transformation of human peripheral blood lymphocytes by a variety of mitogenic stimuli. At a concentration of 2.5 mg/ml, HAFP inhibited the lymphocyte response to phytohemagglutinin, concanavalin A, and rabbit anti-human thymocyte serum, but failed to inhibit the response to pokeweed mitogen. HAFP was able to inhibit the one-way mixed lymphocyte culture at concentrations of 250-500 mug/ml, but failed to inhibit at 100 mug/ml. Exposure of lymphocytes to 2.2 mg/ml of HAFP for 18 hr did not result in significant lymphocytotoxicity, and such cells washed free of HAFP were fully capable of participating in the mixed lymphocyte culture. HAFP did not inhibit lymphocyte E-rosette formation. Fetal HAFP was more effective in inhibiting human lymphocyte responses than hepatoma HAFP. These experiments support the suggestion that HAFP plays an important immunoregulatory role during fetal development, possibly through the suppression of thymus-derived lymphocyte responses to antigenic stimuli; they also suggest that there are important differences in the biological properties of hepatoma and fetal HAFP.

Abstract

Background: Artificially sweetened (AS) and sugar-sweetened (SS) beverages are commonly consumed during pregnancy. A recent Danish study reported that the daily intake of an AS beverage was associated with an increased risk of preterm delivery.

Objective: We examined the intake of AS and SS beverages in pregnant women to replicate the Danish study and observe whether AS intake is indeed associated with preterm delivery.

Design: This was a prospective study of 60,761 pregnant women in the Norwegian Mother and Child Cohort Study. Intakes of carbonated and noncarbonated AS and SS beverages and use of artificial sweeteners in hot drinks were assessed by a self-reported food-frequency questionnaire in midpregnancy. Preterm delivery was the primary outcome, and data were obtained from the Norwegian Medical Birth Registry.

Results: Intakes of both AS and SS beverages increased with increasing BMI and energy intake and were higher in women with less education, in daily smokers, and in single women. A high intake of AS beverages was associated with preterm delivery; the adjusted OR for those drinking >1 serving/d was 1.11 (95% CI: 1.00, 1.24). Drinking >1 serving of SS beverages per day was also associated with an increased risk of preterm delivery (adjusted OR: 1.25; 95% CI: 1.08, 1.45). The trend tests were positive for both beverage types.

Conclusion: This study suggests that a high intake of both AS and SS beverages is associated with an increased risk of preterm delivery.

Abstract

Intron length polymorphisms (ILPs), a type of gene-based functional marker, could themselves be related to the particular traits. Here, we developed a genome-wide cotton ILPs based on orthologs annotation from two sequenced diploid species, A-genome Gossypium arboreum and D-genome G. raimondii. We identified 10,180 putative ILP markers from 5,021 orthologous genes. Among these, 535 ILP markers from 9 gene families related to stress were selected for experimental verification. Polymorphic rates were 72.71% between G. arboreum and G. raimondii and 36.45% between G. hirsutum acc. TM-1 and G. barbadense cv. Hai7124. Furthermore, 14 polymorphic ILP markers were detected in 264 G. hirsutum accessions. Coupled with previous simple sequence repeats (SSRs) evaluations and salt tolerance assays from the same individuals, we found a total of 25 marker-trait associations involved in nine ILPs. The nine genes, temporally named as C1 to C9, showed the various expressions in different organs and tissues, and five genes (C3, C4, C5, C7 and C9) were significantly upregulated after salt treatment. We verified that the five genes play important roles in salt tolerance. Particularly, silencing of C4 (encodes WRKY DNA-binding protein) and C9 (encodes Mitogen-activated protein kinase) can significantly enhance cotton susceptibility to salt stress.
