The molecular genetic background leading to the formation of the human erythroid-specific Xg/CD99 blood groups.

The Xg and CD99 antigens of the human Xg blood group system show a unique and sex-specific phenotypic relationship. The phenotypic relationship is believed to result from transcriptional coregulation of the and genes, which span the pseudoautosomal boundary of the X and Y chromosomes. However, the molecular genetic background responsible for these blood groups has remained undetermined.

The differential expression of the blood group P -A4GALT and P -A4GALT alleles is stimulated by the transcription factor early growth response 1.

Background: The P /P phenotypic polymorphism is one of the earliest blood groups discovered in humans. These blood groups have been connected to different levels of expression of the A4GALT gene in P and P red blood cells; however, the detailed molecular genetic mechanism that leads to these two phenotypes has not been established.

Study Design And Methods: After our previous identification of an association between the single-nucleotide polymorphisms (SNPs) rs2143918 and rs5751348 in A4GALT gene and the P /P phenotype, we conduct a survey of transcription factors that might connect these SNPs with the differential expression of the P -A4GALT and P -A4GALT alleles.

Linking Life Table and Predation Rate for Biological Control: A Comparative Study of Eocanthecona furcellata (Hemiptera: Pentatomidae) Fed on Spodoptera litura (Lepidoptera: Noctuidae) and Plutella xylostella (Lepidoptera: Plutellidae).

To better understand the predator-prey relationship and to compare predation rates, we studied the life table and predation rate of the predator Eocanthecona furcellata Wolff (Hemiptera: Pentatomidae) when reared on two major crucifer pests, Spodoptera litura (F.)
