Alterations in genomic CpG methylation patterns have been found to be associated with cell transformation and neoplasia. Although it is recognized that methylation of CpG residues negatively regulates gene expression, how the various MBPs (methyl-binding proteins) contribute to this process remains elusive. To determine whether the two well characterized proteins MeCP2 (methyl-CpG-binding protein 2) and MBD1 (methyl-CpG-binding domain 1) have distinct or redundant functions, we employed RNAi (RNA interference) to silence their expression in the prostate cancer-derived PC3cell line, and subsequently compared cell growth, invasion and migration properties of these cell lines in addition to their respective mRNA-expressionprofiles. Cells devoid …

Minimally Invasive Papillary Carcinoma Of The Extrahepatic Bile Ducts, Samia Fatima, Zubair Ahmad, Asim Qureshi, Khurram Minhas, Inam Pal
Department of Pathology and Laboratory Medicine
Invasive papillary carcinomas of the Extrahepatic Bile Ducts (EBD) are uncommon (4-5%). The course is less aggressive than conventional adenocarcinomas of the extrahepatic bile ducts. Non-invasive and minimally invasive papillary carcinomas are even rarer, behave as in-situ carcinomas and are associated with excellent long-term prognosis. A variety of lesions of the EBD that show papillary architecture should be distinguished from papillary carcinoma. Here, we report a case of papillary carcinoma of the common bile duct showing minimal invasion. Separation of invasive from non-invasive or minimally invasive papillary carcinoma is critical in estimating the patient outcome.

Dubin-Johnson Syndrome, Aziz-Un Nisa, Zubair Ahmad
Department of Pathology and Laboratory Medicine
A young man presented with recurrent episodes of mild jaundice. Apart from conjugated hyperbilirubinemia, other liver function tests were always normal. Clinical suspicion of Dubin-Johnson syndrome was raised. Liver biopsy showed diffuse deposition of coarse granular dark brown pigment in hepatocytes. Dubin-Johnson syndrome is a benign condition, which results from a hereditary defect in biliary secretion of bilirubin pigments, and manifests as recurrent jaundice with conjugated hyperbilirubinemia. The defect is due to the absence of the canalicular protein MRP2 located on chromosomes 10q 24, which is responsible for the transport of biliary glucuronides and related organic anions into bile. No …

Pathology, East Africa
A fixed-dose combination of artemether-lumefantrine (AL, Coartem®) has shown high efficacy, good tolerability and cost-effectiveness in adults and children with uncomplicated malaria caused by Plasmodium falciparum. Lumefantrine bioavailability is enhanced by food, particularly fat. As the fat content of sub-Saharan African meals is approximately a third that of Western countries, it raises the question of whether fat consumption by African patients is sufficient for good efficacy. Data from healthy volunteers have indicated that drinking 36 mL soya milk (containing only 1.2 g of fat) results in 90% of the lumefantrine absorption obtained with 500 mL milk (16 g fat). African …
