• Methylation analysis for plasma DNA of patients with organ transplantation

  We developed Genetic-Epigenetic Tissue Mapping (GETMap) to determine the tissue composition of plasma DNA carrying genetic variants not present in the constitutional genome through comparing their methylation profiles with relevant tissues. We validated this approach by showing that, in pregnant women, circulating DNA carrying fetal-specific alleles was entirely placenta-derived.

• Analysis of Complex Genomic Rearrangements of Lung Adenocarcinomas

  Lung adenocarcinomas (LADC) are heterogeneous disease with distinct etiology. A majority of tumors are related with tobacco smoking, and some tumors arise from never-smoking or young patients, whose clinical history do not support the environmental carcinogen-induced oncogenes. Here we analyzed complex rearrangements in lung adenocarcinomas including tumors with distinct etiologies.

• Paired exome and low-coverage genome sequencing of osteosarcoma

  We perform longitudinal genome-sequencing analysis of 12 patients with metastatic or refractory osteosarcoma.

• Collection of Genotypic and Ethnographic Information from Individuals of South African Ethnic Groups

  The hunter-gatherers and pastoralists of South Africa retain the highest genetic diversity of any population. Genetic determinants of light skin pigmentation, reduced stature etc and other basic biomedical phenotypes are unique to samples with Southern African hunter-gatherer and pastoralist ancestry or retain ancestral haplotypes not found in other populations.

• Genome sequencing of childhood acute leukemia in Iraq

  Mutations in acute leukemia vary among countries. To obtain a catalog of mutations of acute leukemia in Iraq, we performed a next-generation sequencing study of childhood acute lymphoblastic and myeloid leukemia. We performed whole-genome sequencing or a combination of whole-exome sequencing to identify somatic and germline mutations + targeted sequencing to identify gene fusions.

• Single-cell RNA sequencing dissects gene-environment interactions on gene expression and regulation in immune cells.

  This study aims to dissect gene-environment interactions on gene expression and regulation in immune cells using scRNA-seq data from 120 donors being stimulated with 3 pathogens, for 2 different timepoints. More specifically, we identified context- and cell-type-specific eQTLs and co-expression QTLs in PBMCs.

• ADAPTeR Study: scRNA and scTCR data from TILs from two ccRCC patients treated with anti-PD1

  TILs were extracted from two ccRCC patients treated with (Nivolumab) anti-PD1, one was responsive to treatment, the other non-responsive. IgG4 staining was used to separate cells into anti-PD1 bound and unbound, the samples then underwent paired scRNA and scTCR sequencing on the 10x Genomics platform.

• Defective mitophagy and enhanced oxidative stress dictate regulatory T cell impairment in autoimmunity

  Regulatory T cell (Treg) impairment is a common denominator of autoimmune pathologies. Despite the extensive characterization of Treg cell phenotype in autoimmunity, the molecular mechanisms underlying their deterioration remain ill defined. To investigate Treg dysfunction during autoimmunity we performed transcriptomic analysis of CD4+CD25highCD127- Treg cells from peripheral blood of patients with autoimmunity.
