and engraftment of genetically modified autologous CD34+ cells,
expression of the transduced $beta$-globin gene and
post-transplant transfusion requirements (efficacy-secondary
endpoint). No unexpected safety issues occurred during
conditioning and cell product infusion. Hematopoietic gene
marking was very stable but low, reducing transfusion
requirements in two patients, albeit not achieving transfusion
independence. Our findings suggest that non-myeloablative
conditioning can achieve durable stem cell engraftment but
underscore a minimum CD34+ cell transduction requirement for
effective therapy. Moderate clonal expansions were associated
with integrations near cancer-related genes, suggestive of
non-erythroid activity of globin vectors in stem/progenitor
cells. These correlative findings highlight the necessity of
cautiously monitoring patients harboring globin vectors.},

abstract = {Colorectal cancer (CRC) is a leading cause of cancer death
worldwide, and about 20% is metastatic at diagnosis and

nature of CRC is related to colorectal cancer stem cells
(CCSCs), a small cells population with stemness behaviors and
responsible for tumor progression, recurrence, and therapy
resistance. Growing knowledge of stem cells (SCs) biology has
rapidly improved uncovering the molecular mechanisms and
possible crosstalk/feedback loops between signaling pathways
that directly influence intestinal homeostasis and
tumorigenesis. The generation of CCSCs is probably connected to
genetic changes in members of signaling pathways, which control
self-renewal and pluripotency in SCs and then establish function
and phenotype of CCSCs. Particularly, various deregulated
CCSC-related miRNAs have been reported to modulate stemness
features, controlling CCSCs functions such as regulation of cell
cycle genes expression, epithelial-mesenchymal transition,
metastasization, and drug-resistance mechanisms. Primarily,
CCSC-related miRNAs work by regulating mainly signal pathways
known to be involved in CCSCs biology. This review intends to
summarize the epigenetic findings linked to miRNAome in the
maintenance and regulation of CCSCs, including their
relationships with different signaling pathways, which should
help to identify specific diagnostic, prognostic, and predictive
biomarkers for CRC, but also develop innovative CCSCs-targeted

that directly influence intestinal homeostasis and
tumorigenesis. The generation of CCSCs is probably connected to
genetic changes in members of signaling pathways, which control
self-renewal and pluripotency in SCs and then establish function
and phenotype of CCSCs. Particularly, various deregulated
CCSC-related miRNAs have been reported to modulate stemness
features, controlling CCSCs functions such as regulation of cell
cycle genes expression, epithelial-mesenchymal transition,
metastasization, and drug-resistance mechanisms. Primarily,
CCSC-related miRNAs work by regulating mainly signal pathways
known to be involved in CCSCs biology. This review intends to
summarize the epigenetic findings linked to miRNAome in the
maintenance and regulation of CCSCs, including their
relationships with different signaling pathways, which should
help to identify specific diagnostic, prognostic, and predictive
biomarkers for CRC, but also develop innovative CCSCs-targeted
therapies. |

abstract = {Inference of causality between gene expression and complex traits using Mendelian randomization (MR) is confounded by pleiotropy and linkage disequilibrium (LD) of gene-expression quantitative trait loci (eQTL). Here, we propose an MR method, MR-link, that accounts for unobserved pleiotropy and LD by leveraging information from individual-level data, even when only one eQTL variant is present. In simulations, MR-link shows false-positive rates close to expectation (median 0.05) and high power (up to 0.89), outperforming all other tested MR methods and coloc. Application of MR-link to low-density lipoprotein cholesterol (LDL-C) measurements in 12,449 individuals with expression and protein QTL summary statistics from blood and liver identifies 25 genes causally linked to LDL-C. These include the known SORT1 and ApoE genes as well as PVRL2, located in the APOE locus, for which a causal role in liver was not known.

Inference of causality between gene expression and complex traits using Mendelian randomization (MR) is confounded by pleiotropy and linkage disequilibrium (LD) of gene-expression quantitative trait loci (eQTL). Here, we propose an MR method, MR-link, that accounts for unobserved pleiotropy and LD by leveraging information from individual-level data, even when only one eQTL variant is present. In simulations, MR-link shows false-positive rates close to expectation (median 0.05) and high power (up to 0.89), outperforming all other tested MR methods and coloc. Application of MR-link to low-density lipoprotein cholesterol (LDL-C) measurements in 12,449 individuals with expression and protein QTL summary statistics from blood and liver identifies 25 genes causally linked to LDL-C. These include the known SORT1 and ApoE genes as well as PVRL2, located in the APOE locus, for which a causal role in liver was not known.
