MetabolomicsNext-generation biomonitoring of the early-life chemical exposome in neonatal and infant development

Exposure to synthetic and natural chemicals is a major environmental risk factor in the etiology of many chronic diseases. Investigating complex co-exposures is necessary for a holistic assessment in exposome-wide association studies. In this work, a sensitive liquid chromatography-tandem mass sp...

MetabolomicsComparative characterization of the infant gut microbiome and their maternal lineage by a multi-omics approach

The human gut microbiome establishes and matures during infancy, and dysregulation at this stage may lead to pathologies later in life. We conducted a multi-omics study comprising three generations of family members to investigate the early development of the gut microbiota. Fecal samples from 20...

TranscriptomicsThe Methylome Landscape of Infant B-cell precursor Acute Lymphoblastic Leukemia (iB-ALL)
B-cell acute lymphoblastic leukemia (B-ALL) is the most prevailing childhood cancer. As predicated by its prenatal origin, infant B-ALL (iB-ALL) show a silent mutational landscape irrespective of the MLL rearrangement/status, suggesting that other regulatory mechanisms might be impaired in the conte...

MetabolomicsMultiomic profiling of iron-deficient infant monkeys reveals alterations in neurologically important biochemicals in serum and cerebrospinal fluid before the onset of anemia

The effects of iron deficiency (ID) during infancy extend beyond the hematologic compartment and include short- and long-term adverse effects on many tissues including the brain. However, sensitive biomarkers of iron-dependent brain health are lacking in humans. To determine whether serum and cer...

TranscriptomicsGenotyping of human Infant ALL samples to detect MLL-cooperating aberrations
In this study we explored the genotype of Infant ALL to detect MLL-cooperating aberrations, hidden to conventional techniques. In order to limit further heterogeneity, we focused on patients carrying the t(4;11) translocation, the most frequent genetic abnormality in Infant ALL. Final aim was to get...

TranscriptomicsGene expression of wild-type MLL infant ALL patients
Extensive molecular and prognostic characterization of wild-type MLL infant ALL. Background: Approximately 20% of all infant ALL cases carry wild-type (or germline) MLL genes. To date, wild-type MLL infant ALL patients are generally regarded as young pediatric precursor B-ALL patients, but extensive...

Genomicsmulti-OMICs study of a pair of infant monozygotic twins with concordant B-cell ALL
B-cell acute lymphoblastic leukemia (B-cell ALL) is the most common cancer in childhood. Studying identical twins with B-cell ALL provides a unique and tractable model for deciphering the developmental timing of pre- and post-natal mutations contributing to clonal evolution. To date, this has mainly...

TranscriptomicsPromoter hypermethylation in MLL-r leukemia: biology and therapeutic targeting
MLL-r infant acute lymphoblastic leukemia (ALL) has largely unclear oncogenesis. It has been shown unrelated to copy number change or mutations in the tyrosine kinome. We therefore, explored the possible role of genome wide CpG island hypermethylation in MLL-r infant ALL. We employed the HpaII-ti...

ProteomicsNG2 is a target gene of MLL-AF4 that underlies glucocorticoid resistance in infant MLL-rearranged B-ALL by regulating NR3C1 expression through interaction with FLT3
B-cell acute lymphoblastic leukemia (B-ALL) is the most common pediatric cancer, with long-term overall survival rates of 80%. However, B-ALL harboring rearrangements of the MLL gene (also known as KTM2A), hereinafter termed MLLr B-ALL, is frequently seen in infants and is associated with poor 5-yea...

ProteomicsKMT2A rearranged B lineage infant ALL cell line SEM treated with bortezomib LC-MS/MS
The KMT2A rearranged B lineage infant ALL cell line SEM was treated with the proteasome inhibitor bortezomib followed by a multiplexed mass spectrometry-based proteomic analysis at multiple time points (0, 6, 12, 16, and 20 hours) over 20 hours to further understand the cellular response of these ce...
