Abstract

We evaluated the influence of gene polymorphisms of TLR9 (T1237C; T1486C), IL23R (A1142G), and NOD2 SNP8 (R702W), SNP12 (G908R) and SNP13 (1007fs) on outcome of hematopoietic SCT in a homogenous group of 142 AML patients after non-T-cell-depleted myeloablative transplantation from HLA-identical sibling donors. In our retrospective study, we found that TLR9 gene variant at 1486 influenced transplant outcome. Estimated 5-year OS in patients with the CC gene variant of TLR9 was 70.2% compared with 44.8% (P<0.027) in patients with TC/TT of TLR9 gene. No significant influences on 5-year OS were found for gene polymorphisms of NOD2 or IL23R (A1142G) in this study group. The 5-year treatment-related mortality was lowest in patients with CC gene variant of TLR9 (7.8 vs 23.1%; NS). Acute GVHD grade III-IV was higher in patients with NOD2 gene variants (28 vs 12.8%; P=0.065). In contrast, patients transplanted from donors with the gene variant of IL23R had no occurrence of severe acute GVHD grade III-IV (0 vs 18.4%; P<0.048). However, multivariate analysis confirmed the influence of NOD2 gene variants on the occurrence of acute GVHD grade II-IV after transplant. These results suggest that the gene variants of TLR9, NOD2 and Il23R had inf...Continue Reading

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.

AML: Role of LSD1 by CRISPR (Keystone)

Find the latest rersearrch on the ability of CRISPR-Cas9 mutagenesis to profile the interactions between lysine-specific histone demethylase 1 (LSD1) and chemical inhibitors in the context of acute myeloid leukemia (AML) here.

Allogenic & Autologous Therapies

Allogenic therapies are generated in large batches from unrelated donor tissues such as bone marrow. In contrast, autologous therapies are manufactures as a single lot from the patient being treated. Here is the latest research on allogenic and autologous therapies.

Acute Myeloid Leukemia

Acute myeloid leukemia (AML) is a clinically and genetically heterogeneous disease with approximately 20,000 cases per year in the United States. AML also accounts for 15-20% of all childhood acute leukemias, while it is responsible for more than half of the leukemic deaths in these patients. Here is the latest research on this disease.
