• Whole Exome Sequencing analysis of three tumor biopsies from a LUAD patient

  Whole Exome Sequencing (WES) analysis was performed on three distinct tumor biopsies collected at different time points, along with their matched germline non-tumor sample, from the same LUAD patient. DNA was extracted using the DNeasy Blood and Tissue Kit (Qiagen, Germantown, MD) according to the manufacturer’s instructions and quantified using the Qubit Fluorometer assay (Life Technologies, Carlsbad, CA). To minimize FFPE-related sequencing artifacts (e.g., C:G > T:A transitions), the extracted DNA was treated with the DNA repair enzyme Uracil-DNA-Glycosylase (UDG) following the manufacturer’s protocol (New England Biolabs, Ipswich, MA). Whole-exome capture was performed with the Twist Human Core Exome + RefSeq + Mito-Panel kit (Twist Bioscience), in accordance with the manufacturer’s guidelines. Sequencing generated paired-end 100-bp reads on the Illumina NovaSeq 6000 platform. The resulting reads were aligned to the reference human genome (GRCh38) using the Burrows-Wheeler Aligner (BWA, v0.7.12).

• Single cell RNA sequencing of peripheral blood HSPC from patients with sickle cell anemia and healthy donors

  Neutrophils and monocytes are critical contributors to the pathophysiology of sickle cell anemia (SCA) and are persistently elevated in patients' circulation. While chronic hemolysis has been implicated in this leukocytosis, the underlying mechanisms remain incompletely understood. Our data show a myeloid-skewed transcriptional signature in early progenitor populations, including multipotent progenitors (MPPs) and hematopoietic stem cells (HSCs). Notably, we identify upregulation of the type I interferon signaling pathway in HSPCs as a key driver of early myeloid programming in SCA.

• Tumor-associated neutrophil 1 precursors impair homologous DNA repair and promote sensitivity to PARP-inhibition

  Tumor evolution is one of the major mechanisms responsible for acquiring therapy resistant and more aggressive cancer clones. Whether the tumor microenvironment through immune-mediated mechanisms might promote the development of more aggressive cancer types is crucial for the identification of additional therapeutical opportunities. Here, we identify a subset of tumor-associated neutrophils, defined as tumor-associated neutrophil precursors (PreNeu). These PreNeu are enriched in highly proliferative hormone-dependent breast cancers and impair DNA repair capacity

• Access to "BMP9 controls pulmonary vascular growth and remodeling"

  Pulmonary arterial hypertension (PAH) and hereditary hemorrhagic telangiectasia (HHT) are two distinct vascular diseases linked to impaired signaling through bone morphogenetic protein (BMP) receptor complexes in endothelial cells. Although BMP-9 plays a central role in activating this pathway by binding to ALK1 and BMPR-II, its precise function in the pulmonary microvasculature has remained unclear. In this study, we uncover a previously unrecognized role for BMP-9 in regulating pulmonary vascular architecture and homeostasis. Our findings demonstrate that BMP-9 signaling intersects with VEGF pathways and contributes to the delicate balance between vascular growth and remodeling in the lungs. We also show that disruption of this pathway can shift vascular responses toward an HHT-like state, potentially altering disease susceptibility. These insights offer a unique perspective on how BMP-9 and ALK1 shape pulmonary vascular biology and suggest that targeting this axis could inform future strategies for treating complex vascular diseases such as PAH.
