The activation of B cell specific genes, such as CD19 and PAX5 is a hallmark of t(8;21) acute myeloid leukemia (AML) which expresses the translocation product RUNX1/ETO. PAX5 is an important regulator of B lymphoid development and blocks myeloid differentiation when ectopically expressed. To understand the molecular mechanism of PAX5 ...

Chronic opioid usage (COU) for analgesia is common among patients with end-stage renal disease. In order to test whether a prior history of COU negatively affects post-kidney transplant outcomes, we retrospectively examined clinical outcomes in adult kidney transplant patients. Among 1064 adult kidney transplant patients, 452 (42.5%) reported the presence ...

ABSTRACT Clinical outcomes for patients with multiple myeloma (MM) have improved substantially since the introduction of novel agents, including the proteasome inhibitor bortezomib and the immunomodulatory drugs thalidomide and lenalidomide. However, most patients with MM eventually relapse and prognosis remains poor among patients with relapsed and/or refractory disease. Combination therapy ...

Vertical migrations of living organisms and settling of particle-attached organisms lead to uneven distributions of biota at different depths in the water column. In ballast tanks, heterogeneity could lead to different population estimates depending on the portion of the discharge sampled. For example, concentrations of organisms exceeding a discharge standard ...

Locomotion in living birds (Neornithes) has two remarkable features: feather-assisted flight, and the use of unusually crouched hindlimbs for bipedal support and movement. When and how these defining functional traits evolved remains controversial. However, the advent of computer modelling approaches and the discoveries of exceptionally preserved key specimens now make ...

HsaF and HsaG are an aldolase and dehydrogenase from the cholesterol degradation pathway of M. tuberculosis. HsaF could be heterologously expressed and purified as a soluble dimer, but the enzyme was inactive in the absence of HsaG. HsaF catalyzes the aldol cleavage of 4-hydroxy-2-oxoacids to produce pyruvate and an aldehyde. ...

All cells perceive and respond to environmental stresses through elaborate stress-sensing networks. Yeast cells sense stress through diverse signaling pathways that converge on the transcription factors Msn2 and Msn4, which respond by initiating rapid, idiosyncratic cycles into and out of the nucleus. To understand the role of Msn2/4 nuclear localization ...
