Separation of chronic myeloid leukemia stem cells from normal hematopoietic stem cells at single-cell resolution

We provide whole exome DNA sequening data in fastq format for 23 clinical samples of chronic myeloid leukemia stem cells (CML-SC) plus two buccal swipes derived normal samples. CML samples are comprised of 4 to 8 replicates from two patients, at diagnosis and after treatment. Single CML stem cells before treatment and single non-transformed hematopoietic stem cells (HSC) at remission were selected from bone marrow samples by FACS, according to newly identified genetic markers CD33+CD26+ at diagnosis and CD33+CD26-/CD33-CD26- at remission. WES libraries of colony forming assays derived CML-SC and HSC populations were prepared using Agilent SureSelect Human All Exon V6 kit and sequenced running 150 cycles (2x 75bp paired-end) on an Illumina NextSeq 500 platform.

Single cell resolution landscape of hypomutated childhood cancers

A paradigm of childhood cancers is that they have a low mutation burden, with some ostensibly bearing fewer mutations than the normal tissues from which they derive. We set out to resolve this paradox by examining paediatric renal cancers with exceptionally few mutations using high resolution, high depth sequencing approaches. We found that apparent hypomutation was the result of unusual clonal architecture due to a normal tissue-like mode of tumour evolution, raising the possibility that the mutation burden of some cancers has been systematically misjudged.

This project aims to study human memory capacity, including short-term memory and long-term memory, systematically via genome-wide association studies

Development of high-throughput genotyping platforms provides an opportunity to identify new genetic elements related to complex cognitive functions. Taking advantage of multi-level genomic analysis, here we studied the genetic basis of human short-term (STM, n=1,620) and long-term (LTM, n=1,526) memory functions. Heritability estimation based on single nucleotide polymorphism showed moderate heritability of short-term memory but very low heritability of long-term memory. In a two-step genome-wide association study, the markers rs13151012 and rs1558360 passed genome-wide significance (p < 5×10-8) in digit-span STM task and for the first principal component shared by two STM tasks; however, none of them survived the replication. In turn, we selected the ten most significant single nucleotide polymorphisms (SNPs) for replication tests. Among them, a SNP near ZFAT was significantly associated with STM performance in another independent population of 2,789; a polymorphism within BCAT2 was significantly associated with LTM in another independent population of 1,865. Furthermore, we performed a pathway analysis based on the current genomic data and found six pathways significantly associated with STM capacity and one pathway associated with LTM capacity.

Advanced Genomic Techniques in Sequencing of Colorectal Cancer

We developed a method that uses allelic imbalance information in combination with phased genomic sequencing to generate mega-haplotypes that can encompass entire chromosome arms. We applied this technique to characterize aneuploidy and chromosomal alterations in colorectal cancers.

Genomic Characterization of Brain Metastases from Lung Cancer

Metastatic disease to the brain is associated with a poor prognosis. Our understanding of the genetic drivers of metastasis remain limited. Whole-exome sequencing was performed from brain metastases from lung adenocarcinoma to identify putative drivers of metastatic progression.

MET amplification in gastric cancer

Targeting MET in gastric and gastroesophageal junction adenocarcinoma (GC) with monoclonal antibodies or tyrosine kinase inhibitors has had limited success. We hypothesize that other prognostic and response determining genetic alterations explain the poor outcome and lack of response to MET-targeted therapies.

Target bisulfite sequencing of uterine cervical cancer

We performed targeted bisulfite sequencing of the HLA-A promoter region in cervical tissue samples to investigate DNA methylation patterns that regulate immune recognition and antigen presentation, which may influence viral immune surveillance and malignant transformation in cervical pathology.
