The newfound relationship between extrachromosomal DNAs and excised signal circles

FEBS Letters, EarlyView.
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

Nonlinear Static Analysis of an Asphalt Concrete Core Dam dor Comparison of Three Constitutive Models

Archives of Civil Engineering, 2012
The goal of this work is to compare different constitutive models in the nonlinear static characteristic analysis of asphalt concrete core dams. The Duncan E- μ model, Duncan E-B model and double-yield-surface model are three major constitutive models in

Numerical Study on Seismic Behavior of Moment-Resistant Steel Frames with Hybrid Masonry Infill [PDF]

Journal of Structural and Construction Engineering, 2020
Hybrid masonry system is a new structural system, in which the masonry panels link to the frame with steel plate connections. Hybrid masonry uses masonry infill for lateral stiffness and strength within frames in addition to supporting out-of-plane ...

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

FEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

LINC01116, a hypoxia‐lncRNA marker of pathological lymphangiogenesis and poor prognosis in lung adenocarcinoma

Molecular Oncology, EarlyView.
The LINC01116 long noncoding RNA is induced by hypoxia and associated with poor prognosis and high recurrence rates in two cohorts of lung adenocarcinoma patients. Here, we demonstrate that besides its expression in cancer cells, LINC01116 is markedly expressed in lymphatic endothelial cells of the tumor stroma in which it participates in hypoxia ...
