Background: Chronic lymphocytic leukemia (CLL) is the most common adult human leukemia. Studies revealed that microRNAs (miRNAs) can function as oncogenes or tumor suppressors in CLL and that the expression of miRNAs, such as miR-193b-3p and miR-376a-3p change in several diseases. We aimed to elucidate the changes in miR-193b-3p and miR-376a-3p expression in CLL and determine their potential as...

The human leukocyte antigen G (HLA-G) molecule exhibits limited tissue distribution, low polymorphism and alternative splicings that generate seven HLA-G isoforms. HLA-G exerts multiple immunoregulatory functions. Recent studies indicate an ectopic up-regulation in tumor cells that may favor their escape from anti-tumor immune responses. This study it is an effort to clarify the presence of HLA...

In CD34(+) acute myeloid leukemia (AML), the malignant stem cells reside in the CD38(-) compartment. We have shown before that the frequency of such CD34(+)CD38(-) cells at diagnosis correlates with minimal residual disease (MRD) frequency after chemotherapy and with survival. Specific targeting of CD34(+)CD38(-) cells might thus offer therapeutic options. Previously, we found that C-type lecti...

Tim-3 is a negative immunoregulator in anti-tumor response, but its mechanism chronic lymphocytic leukemia (CLL) not yet clear. The aim of this study was to understand the role Galectin-9/Tim-3 signaling pathway regulation CD4+ T cell subsets CLL patients. Flow cytometry results showed that number Treg cells obviously increased, and there significant Treg/Th17 imbalance In addition, overexpress...

Introduction: Venetoclax has emerged as a breakthrough treatment which revolutionized the therapeutic paradigm of chronic lymphocytic leukemia (CLL). This is primarily attributed to efficacy venetoclax time-limited, chemo-free, therapy in field dominated by targeted agents given on continuous schedule. Furthermore, compelling clinical data support use combination with other hope preventing drug...

Chronic lymphocytic leukemia (CLL) rarely exhibits an aggressive clinical course and its patients often have chromosomal deletions or additions. Furthermore, reciprocal translocations are barely observed in CLL. There have only been a few reports of CLL with t(1;6), and here we report the first Asian case of CLL with reciprocal translocation t(1;6). Since our case and previously reported CLL pa...

expressed in early stages of CLL than in advanced CLL and that its expression is lower in patients with high-risk CLL. The association of LAIR1 expression with commonly recognized clinical and biological variables, and its prognostic role in patients with CLL is still unknown. In this study we analyzed LAIR1 expression in a prospective cohort of 311 unselected CLL patients consecutively enrolle...

Chronic lymphocytic leukemia (CLL) is an indolent lymphoproliferative disorder characterized by both circulating peripheral disease as well as involvement of the lymph nodes and bone marrow. Increasing evidence suggests that the stromal microenvironment provides anti-apoptotic and pro-survival signals to CLL cells, and may contribute significantly to resistance to a wide variety of treatments. ...

To identify novel genes involved in the molecular pathogenesis of chronic lymphocytic leukemia (CLL) we performed a serial analysis of gene expression (SAGE) in CLL cells, and compared this with healthy B cells (nCD19(+)). We found a high level of similarity among CLL subtypes, but a comparison of CLL versus nCD19(+) libraries revealed 55 genes that were over-represented and 49 genes that were ...
