The effects of Yap1-Scribble on hematopoietic stem cells https://doi.org/10.1182/blood.2019004113YAP1 and its like-for-like Taz largely control the growth of endotudial tissue.
althoff and others have confirmed that the adaptive response of hematopoietic stem cells (HSC) to the intense depends on YAP1 and Taz.
the absence of YAP1 and Taz can lead to the loss of HSC stationary, symmetrical self-renewal capabilities, making HSC more susceptible to the effects of the series of myelin-fluorouracil therapy.
this effect depends on the cell slurry polarization that YAP1 is dominated by its PDZ domain-mediated interaction with scaffolding Scribble.
Scrible and YAP1 to co-control the activity of cytoclytic Cdc42 and the fate of HSC in the body.
Scribble deficiency can disrupt the copolarization of YAP1 and Cdc42, reducing the activity of Cdc42, resulting in an increase in HSC in self-renewal with competitive reconstruction advantages.
data show that Scribble/YAP1 copolarization is essential for HSC asymmetric division and destiny activity on which CdC42 depends.
combination of Scribble, YAP1, and Taz can lead to transcriptional ups, Rac activation, and HSC adaptive recovery of Rac-specific ostrich nucleotide exchange factors.
Scrible linked Cdc42 to hippo's signal cascading cell pulp function, which determines the fate of the HSC.
: MDS/MPN Genetic Heterogeneity https://doi.org/10.1182/blood.2019004229 More than 90% of myeloid-related genes in MDS/MPN cases have somatic cell mutations, but molecular data are not currently included in the diagnostic criteria.
Palomo et al. used genome-wide sequencing techniques to quantate mutations in 367 adult MDS/MPN patients, including 119 cases of chronic myeloid monocytoblast leukemia (CMML), 71 cases of atypical chronic granulocytic leukemia (aCML), There were 71 cases of MDS/MPN (MDS/MPN-RS-T) and 106 cases of unstypeed MDS/MPN (MDS/MPN-U) with increased ring iron granulocytes and platelets.
30 ≥ 30 genes carried duplicate mutations in 3 percent of the individuals in the queue.
the distribution and cloning structure of relapsed mutant genes are different between MDS/MPN subtypes.
statistical analysis showed that there was a significant correlation between relapsed mutant genes, as was the correlation between genotypes and esotypes.
researchers also found that specific gene combinations were associated with different subsypes of MDS/MPN and were associated with most other MDS/MPN subsypes (e.g. TAT2-SRSF2 in CMML, ASXL1-SETBP1 in aCML, or SF3B1-JAK2 in MDS/MPN-RS-T).
patients with MDS/MPN-U had the highest heterogeneity and exhibited different molecular spectrometums, similar to those observed in other MDS/MPN subtypes, which were associated with patient prognostication.
specific gene mutations can also affect the prognosm of different MDS/MPNs, which may also be relevant for clinical decision-making.
:3: VEGF-C protects the integrity of the micro-environment around bone marrow blood vessels https://doi.org/10.1182/blood.2020005699 Hematopoietic Stem Cell (HSC) resides in the bone marrow (BM) stem cell niche, an important source of HSC regulating signals.
and chemotherapy can damage the micro-environment of HSC, including its sinus-like blood vessels and vascular cells, leading to a slow recovery of hematosis.
, identifying factors that protect the HSC micro-environment in injury can provide important therapeutic opportunities to improve hematocyte regeneration.
researchers recently revealed the key functions of vascular enditer growth factor C (VEGF-C) in maintaining the integrity of the micro-environment around BM blood vessels and improving the recovery of BM micro-environment after radiation-induced injury.
can lead to damage to the micro-environment around BM blood vessels by knocking out or conditioning the removal of endothelectocytes or Leptin-positive (LepR-plus) cells.
, Vegfc in depleted microencellular environments can delay post-transplant hematosis by reducing endothelectal cell proliferation and LepR-plus cell regeneration.
VEGF-C by adenovirus vector exgencity can promote post-radiation hematosis recovery by accelerating the regeneration of endothorphic cells and LepR-plus cells and increasing the expression of hematogenespheric regeneration factors.
: The relationship between plasma growth differentiation factor 15 levels and risk of venous thrombosis https://doi.org/10.1182/blood.2019004572 growth differentiation factor 15 (GDF-15) is a marker of inflammation and oxidative stress and has become a biological marker of arterial cardiovascular disease.
, however, the relationship between GDF-15 and venous thromboembolism (VTE) remains uncertain.
researchers recently investigated the relationship between plasma GDF-15 levels and the risk of future venous thrombosis, and used The Mendel Randomization (MR) method to explore the possibility of causation.
a population-based nested case-control study that recruited 416 patients with venous thromboembolism and 848 control volunteers.
the results, the OR value of VTE increased in the GDF-15 quarterile.
in age- and gender-adjusted models, subjects with GDF15 values in the highest quarteriles (≥358pg/mL) had an OR with VTE of 2.05 compared to subjects with ALTF15 values at the lowest quarteriles (-lt;200pg/mL).
orS remained essentially unchanged after further correction of body mass index, smoking, hormone therapy, physical activity, and C-reactive proteins.
similar results in induced/non-induced events, deep vein thrombosis, and pulmonary embolism.
consistent with SNPs forecasts, the GDF-15 level is independent of VTE in MR.
