Inhibition of CDK9 enhances AML cell death induced by combined venetoclax and azacitidine

Molecular Oncology, EarlyView.
The CDK9 inhibitor AZD4573 downregulates c‐MYC and MCL‐1 to induce death of cytarabine (AraC)‐resistant AML cells. This enhances VEN + AZA‐induced cell death significantly more than any combination of two of the three drugs in AraC‐resistant AML cells.

Design and characterization of a lumped element single-ended superconducting microwave parametric amplifier with on-chip flux bias line

, 2013
We demonstrate a lumped-element Josephson parametric amplifier, using a single-ended design that includes an on-chip, high-bandwidth flux bias line. The amplifier can be pumped into its region of parametric gain through either the input port or through ...

Adaptaquin is selectively toxic to glioma stem cells through disruption of iron and cholesterol metabolism

Molecular Oncology, EarlyView.
Adaptaquin selectively kills glioma stem cells while sparing differentiated brain cells. Transcriptomic and proteomic analyses show Adaptaquin disrupts iron and cholesterol homeostasis, with iron chelation amplifying cytotoxicity via cholesterol depletion, mitochondrial dysfunction, and elevated reactive oxygen species.

A 24-GHz, +14.5-dBm fully integrated power amplifier in 0.18-μm CMOS [PDF]

, 2005
A 24-GHz +14.5-dBm fully integrated power amplifier with on-chip 50-[ohm] input and output matching is demonstrated in 0.18-μm CMOS. The use of substrate-shielded coplanar waveguide structures for matching networks results in low passive loss and small ...
