The origin of CDK regulation [PDF]

Nature Cell Biology, 2001
The initiation of DNA replication is restrained by Cip/Kip proteins that inhibit Cdk2. Degradation of Xenopus Xic1, a Kip1 orthologue, is dependent on its recruitment to replication origins. This ensures that activation of Cdk2 and (subsequent initiation of replication) is co-ordinately regulated at, and localised to, replication origins.

Human metabolism and elimination of the anthocyanin, cyanidin-3-glucoside: a 13C-tracer study [PDF]

, 2013
BACKGROUND: Evidence suggests that the consumption of anthocyanin-rich foods beneficially affects cardiovascular health; however, the absorption, distribution, metabolism, and elimination (ADME) of anthocyanin-rich foods are relatively unknown. OBJECTIVE:

Halorotetin B, A Novel Terpenoid Compound Derived from Marine Ascidian, Suppresses Tumor Growth by Targeting the Cell Cycle Regulator UBE2C

Advanced Science, EarlyView.
Halorotetin B, a novel small‐molecule terpenoid identified from an edible marine ascidian, exhibits strong anti‐tumor activity both in vitro and in vivo through direct targeting UBE2C to induce tumor cell cycle arrest and then lead tumor cell senescence. As a newly discovered UBE2C inhibitor, Halorotetin B can serve as a novel potential cell senescence

Redox signaling, Nox5 and vascular remodeling in hypertension [PDF]

, 2015
Purpose of review: Extensive data indicate a role for reactive oxygen species (ROS) and redox signaling in vascular damage in hypertension. However, molecular mechanisms underlying these processes remain unclear, but oxidative post-translational ...

T Cell Exhaustion in Cancer Immunotherapy: Heterogeneity, Mechanisms, and Therapeutic Opportunities

Advanced Science, EarlyView.
T cell exhaustion limits immunotherapy efficacy. This article delineates its progression from stem‐like to terminally exhausted states, governed by persistent antigen, transcription factors, epigenetics, and metabolism. It maps the exhaustion landscape in the TME and proposes integrated reversal strategies, providing a translational roadmap to overcome

Multisite phosphorylation code of CDK [PDF]

Nature Structural & Molecular Biology, 2019
The quantitative model of cyclin-dependent kinase (CDK) function states that cyclins temporally order cell cycle events at different CDK activity levels, or thresholds. The model lacks a mechanistic explanation, as it is not understood how different thresholds are encoded into substrates.

Effective Material Stiffness in Curved Actuators

Advanced Intelligent Systems, EarlyView.
A new actuator effective material stiffness measurement method is created. It produces a new metric called shape actuation modulus with the potential to help design actuators. This method shows that the smaller the curvature of hinge‐shaped actuators, the stiffer they are.

Comparing EEG patterns of actual and imaginary wrist movements - a machine learning approach [PDF]

, 2005
Our goal is to develop an algorithm for feature extraction and classification to be used in building brain-computer interfaces. In this paper, we present preliminary results for classifying EEG data of imaginary wrist movements.

Deficiency of G1 regulators P53, P21Cip1 and/or pRb decreases hepatocyte sensitivity to TGFbeta cell cycle arrest [PDF]

, 2015
TGFbeta is critical to control hepatocyte proliferation by inducing G1-growth arrest through multiple pathways leading to inhibition of E2F transcription activity.
