(A) Representative anti-EGFP immunohistochemistry (IHC) images of bone marrow corresponding to the tibia. To induce Cre expression, mice were intraperitoneally injected with 15 μg/g body weight of polyinosinic:polycytidylic acid (pI:pC; Sigma-Aldrich) 3 times per week for a total of 5 weeks. To this end, we performed a longitudinal study to follow telomere length in peripheral blood (PBMCs) over time using telomere HT-Q-FISH technology.34  To do so, we extracted blood at 4 different time points (time point 1, 30 days after bone marrow engraftment; time point 2, 5 weeks after pI:pC treatment; time point 3, 2 months after treatment with the AAV9 vectors; and time point 4, 4 months after treatment with the AAV9 vectors) (note: longitudinal telomere measurements were done on PBMCs from mice that did not develop aplastic anemia). In agreement with longer telomeres in peripheral blood cells in the AAV9-Tert-treated mice, we found that AAV9-Tert-treated mice also had significantly longer telomeres in the bone marrow compared with mice treated with the empty vector (Figure 3D-F). AAV9-Tert treatment causes telomere elongation in blood and bone marrow. 2011;2011:480-486.

AAV9-Tert treatment rescues the aplastic anemia phenotype in Trf1lox/lox mice. Here, we set out to test the hypothesis of whether increased expression of telomerase through systemic virus-based Tert delivery may delay or prevent the emergence of aplastic anemia provoked by short telomeres.

Our results show that telomerase treatment is sufficient to attenuate telomere attrition and HSPC depletion with time, thus significantly preventing death by bone marrow failure. Indeed, throughout the course of the experiment, AAV9-empty-treated mice showed a total decrease in average telomere length of 12 kb, whereas mice treated with AAV9-Tert showed re-elongation of telomeres to a similar telomere length as before the induction of Trf1 deletion by pI:pC treatment (Figure 3C).

In both groups, aplastic anemia was determined as the cause of death in those mice showing a drastic drop in platelet counts and hemoglobin levels at the time of death (Figure 2D-E) and presenting with severe bone marrow hypoplasia and aplasia after postmortem histopathological analysis of bone marrow sections (Figure 2F). Telomerase gene therapy in a mouse model of aplastic anemia targets the bone marrow and provides increased and stable telomerase expression. Abnormal telomere shortening is also described in cases of acquired aplastic anemia, most likely secondary to increased turnover of bone marrow stem and progenitor cells. We have previously developed a telomerase (Tert) gene therapy using adeno-associated virus (AAV)9 vectors,18  which attenuated or reverted aging-associated telomere erosion in peripheral blood mononuclear cells (PBMCs).18, To test the efficacy of this strategy in the treatment of aplastic anemia, we first used a mouse model of aplastic anemia generated by us in which we depleted the TRF1 shelterin protein specifically in the bone marrow, leading to a bone marrow phenotype that recapitulates the main pathological findings of human aplastic anemia patients, including extreme telomere shortening.19,20  In particular, partial depletion of the Trf1 gene specifically in bone marrow causes severe telomere uncapping and provokes a persistent DNA-damage response at telomeres, which in turn leads to a fast clearance of those HSPCs deficient for Trf1.

Telomerase expression leads to telomere elongation and subsequently to the reversal of aplastic anemia phenotypes. Explore historical records and family tree profiles about Christian Baer on MyHeritage, the world's family history network. When telomeres reach a critically short length, their protective function is impaired, eliciting a persistent DNA-damage response at chromosome ends, which leads to cellular senescence or cell death.9,10  Hematopoietic stem cells, in contrast to most somatic cells, can activate telomerase; however, this is insufficient to prevent telomere attrition with aging, thus eventually leading to loss of the regeneration potential of hematopoietic stem cells.11  In line with this, recipients of bone marrow transplants have shorter telomeres than their donors, suggesting that telomerase cannot fully compensate for the increased cell proliferation that occurs during the engraftment phase of the transplanted bone marrow.12  Telomeres also show an accelerated rate of shortening in patients with aplastic anemia compared with healthy individuals, most likely due to a higher than normal number of cell divisions in the aplastic anemia cases.13, Accelerated telomere shortening due to defects in telomerase or other telomere maintenance genes prematurely limits the proliferation potential of cells, including stem cells, leading to decreased tissue renewal capacity.9,14  Highly proliferative tissues such as the hematopoietic system are particularly vulnerable to defects in telomere maintenance genes, leading to severe disorders such as aplastic anemia.15  As an example, the telomeropathy dyskeratosis congenita (DKC) has been linked to mutations in 11 genes that encode components of the telomerase complex (TERT, TERC, DKC1, NOP10, and NHP2) or of the telomere capping complex shelterin (TIN2). and C.B.

Other genes altered in DKC encode for accessory proteins important for telomerase assembly and trafficking (CTC1, ACD7 [alias TPP1], and TCAB1) or for telomere replication (RTEL1).16  Mutated PARN was also recently linked to reduced messenger RNA (mRNA) levels of several key genes in telomere maintenance.17  In all these cases, DKC is characterized by very short telomeres.

Aplastic anemia is a potentially life-threatening, rare, and heterogeneous disorder of the blood in which the bone marrow cannot produce sufficient new blood cells due to a marked reduction of immature hematopoietic stem and progenitor cells (HSPCs).1,2  The main disease manifestations are pancytopenia and marrow hypoplasia, which can emerge at any stage of life but are more frequent in young individuals (age 10-25 years) and in the elderly (>60 years).3  Aplastic anemia can be acquired or inherited.

To rule out the possibility that AAV9 may be targeting only bone marrow stroma cells, we demonstrated significantly increased Tert mRNA expression both in isolated hematopoietic stem cells (lin−, Sca-1+, c-kit+) and in lineage-committed bone marrow cells (lin+) from mice treated with AAV9-Tert compared with mice treated with the AVV9-empty vector. Increased telomere fragility and fusions resulting from TRF1 deficiency lead to degenerative pathologies and increased cancer in mice. Es bedarf des zuverlässigen Schöpfens, oder des Ziehen des Stöpsels oder wenn es dufte läuft, dreht jemand am Haupthahn das Wasser ab. In agreement with the known tropism of the AAV9 serotype, we found a stronger induction of Tert in organs such as heart and liver, which are preferential AAV9 targets (supplemental Figure 1, available on the Blood Web site).32  We then studied Tert mRNA expression specifically in the blood-forming compartments of the bone marrow. Google Scholar, Inst. Telomere length is controlled by the ribonucleoprotein enzyme telomerase, which can add telomeric sequences onto telomeres de novo. The disease can be hereditary or acquired and develops at any stage of life. In this regard, we previously demonstrated that adipocytes are efficiently targeted by AAV9.33  Moreover, the relative lower fold changes in Tert in HSPCs compared with total bone marrow may also be due to higher levels of endogenous Tert in HPSCs compared with whole bone marrow.

In agreement with previous findings, we found a dramatic drop in telomere length of ∼10 kb in all mice after induction of Trf1 deletion with pI:pC and prior to treatment with the gene therapy vectors (Figure 3A; compare time points 1 and 2).19,20  We observed a further drop in telomere length in those mice treated with the AAV9-empty vector when comparing time point 4 with time point 2 in this mouse cohort (Figure 3A-B). (C) Kaplan-Meier survival curves show that AAV9-Tert treatment improves survival of mice with very short telomeres in the bone marrow due to Tert deficiency specifically in the bone marrow (irradiated wild-type mice transplanted with G3 Tert−/− bone marrow). European Energy Exchange AG. Christian Bär The theme is the influence of the spin structure on the Dirac spectrum of a spin manifold. Because aplastic anemia in our mouse model is caused by extreme telomere shortening,19,20  we next compared the dynamics of telomere length in mice treated with AAV9-Tert vs mice treated with the empty vector.
