Methods Studied groups A total of 130 samples of paraffin-embedded tissue collected from HL patients were obtained from the Departments of Pathology PD173074 in vivo at both Royal Medical Services and King Abdullah University Hospital. Patients included in the study are those of age more than 15-year old with HL, who received only ABVD regimen as initial chemotherapy. Patients were divided into two groups; complete response (n = 96) and relapsed disease (n = 34) according to International Workshop Criteria (IWC) [11].

Complete response (CR) was defined as 1) complete disappearance of all detectable evidence of disease on computed tomography (CT), 2) all disease-related symptoms, 3) normalization of biochemical abnormalities, 4) normal bone marrow biopsy, and 5) regression of nodes on CT of more than 1.5 cm in their axial diameter to less than 1.5 cm, and nodes of 1.1-1.5 to less than 1 cm. Relapsed disease (RD) was defined as: 1) the appearance of any new lesion 2) or increase in the size of more than 50% of previously involved sites or nodes in patients who achieved CR or Cru (uncertain). CRu corresponds

to CR criteria but with a residual mass more than 1.5 cm in greatest axial diameter that has regressed by more than 75% [11]. Peripheral blood samples were collected from 120 healthy young volunteers as a control group from the same patient’s DNA Damage inhibitor geographical areas. Informed written consents were obtained from the participants in accordance with the requirements of the Institutional Review Boards of Jordan University of Science and Technology. DNA extraction DNA was extracted from paraffin embedded tissue samples using QIAamp DNA FFPE Tissue Kit (QIAGEN, California, USA) according to standard protocol provided by the manufacturer. Approximately, 3-5 sections of 5 μm thick were cut from each sample and used for DNA extraction. Venous blood samples were collected in EDTA tubes and obtained from young healthy control group.

Methane monooxygenase DNA samples were stored at -20°C until used. Genotyping

The polymorphism C3435T was analyzed using polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP) method. Desired DNA target sequence (197) was amplified as described by Cascorbi et al. [12] using a forward primer (5′-TGT TTT CAG CTG CTT GAT GG -3′) and a reverse primer (5′-AAG GCA TGT ATG TTG GCC TC-3′). The reaction mixture of 25 μL contained 50 ng of genomic DNA, 0.5 μL of each primer, 12.5 μL of the green master mix, and 1.5-9.5 μL of deionized water. The reaction mixture was initially denatured at 94°C for 2 minutes, followed by 35 cycles of denaturation at 94°C for 30 s, annealing at 60°C for 30 s and extension at 72°C for 30 s. The termination elongation was performed at 72°C for 7 minutes.
