Article Title: The BCL2 gene is regulated by a special AT-rich sequence binding protein 1-mediated long range chromosomal interaction between the promoter and the distal element located within the 3?-UTR
Journal: Nucleic Acids Research
Figure Legend Snippet: 3C Analysis of the interaction between the mbr and the BCL2 promoter region in vivo . The scheme of BCL2 gene with the positions of restriction sites and positions of primers was indicated ( A ). The 3C experiments were performed as described in the ‘Materials and Methods’ section. Briefly, formaldehyde was used to crosslink protein–DNA interactions in intact nuclei. The crosslinked chromatin was then digested by AseI ( B ) or HindIII ( C ), followed by ligation. Physical interaction between mbr and SBS1 or SBS2 was then determined by specific PCRs that detected hybrid fragments containing either mbr/SBS1 sequences or mbr/SBS2 sequences. 3C data demonstrated that the mbr specifically interacted with SBS1 (B, up panel), but not with SBS2 (C, up panel). PCR products from AseI (B) or HindIII (C) digested crosslinked chromatin without ligation and non-crosslinked genomic DNA with or without ligation were used as negative controls. The bands shown in the bottom panels of B and C represented the PCR products from genomic DNA that was not cut by any restriction enzyme, which were used as the loading control.
Techniques Used: In Vivo, Ligation, Polymerase Chain Reaction

Article Title: High Frequency of Cryptosporidium hominis Infecting Infants Points to A Potential Anthroponotic Transmission in Maputo, Mozambique
Figure Legend Snippet: Genotyping of the Cryptosporidium parasites by PCR-RFLP targeting 18S rRNA gene. M, molecular size makers (100 bp). Lane 1: C. parvum ; Lanes 2, 3 and 4: C. hominis and Lane 5: mixed infection with C. hominis and C. parvum . The upper lanes show SspI digestion products showing a molecular size from 111 bp to 449 bp, and the lower lanes show AseI digestion products with molecular size of approximately 104 bp to 628 bp.
Techniques Used: Polymerase Chain Reaction, Infection
