IqgC is a potent regulator of macropinocytosis in the presence of NF1 and its loading to macropinosomes is dependent on RasG.

RasG is a major regulator of macropinocytosis in . Its activity is under the control of an IQGAP-related protein, IqgC, which acts as a RasG-specific GAP (GTPase activating protein). IqgC colocalizes with the active Ras at the macropinosome membrane during its formation and for some time after the cup closure.

COX-2 expression in fibroblast aggregates as a functional indicator for the anti-inflammatory activity of leukemia patients' bone marrow-derived hematopoietic cells.

Reciprocal communication between hematopoietic cells and their surrounding bone marrow stroma is crucial for normal progression of hematopoiesis. This complex network of cell-to-cell signals in the microenvironment involves both cell contact-mediated and paracrine cues. In hematological malignancies the intricate balance is, however, disrupted to support cancer progression.

Resistance of human regulatory Foxp3+ T cells to normobaric hyperoxia exposure under resting and stimulating conditions.

Oxygen tension levels may modulate immune responses. Evidence shows that hyperoxia influences the risk of infection, autoimmunity and alloreactivity and hence is a possible therapeutic option in a number of disorders. Regulatory T cells (Tregs) play a central role in tolerance maintenance, but their behaviour under hyperoxia is largely unknown.

Minimal residual disease detection using real-time quantitative PCR analysis of immunoglobulin and T-cell receptor gene rearrangements in the non-MRD-based ALL IC-BFM 2002 protocol for childhood ALL: Slovak experience.

Acute lymphoblastic leukemia is the most common form of cancer in children. The 10-year event-free survival ranged from 77 to 85% after having achieved complete remission rates of 93% or higher. The main cause of treatment failure is relapse arising from outgrowth of residual leukemic cells that are refractory to therapy.
