From a quantum mechanical description of the assembly processes in microtubules to their semiclassical nonlinear dynamics [PDF]

Quantum Biosystems (2007) Vol. 1, 1 - 20, 2007
In this paper a quantum mechanical description of the assembly/disassembly process for microtubules is proposed. We introduce creation and annihilation operators that raise or lower the microtubule length by a tubulin layer. Following that, the Hamiltonian and corresponding equations of motion are derived that describe the dynamics of microtubules ...

Ultrasound‐Assisted H2 Transmitter Enables Hydrogen‐Gene Therapy to Prevent Anesthesia/Surgery‐Induced Cognitive Impairment

Advanced Science, EarlyView.
Postoperative cognitive dysfunction (POCD) remains a challenge with no effective treatments. This study introduces a novel hydrogen‐gene therapy strategy, combining focused ultrasound and siRNA delivery via hydrogen emitters, to repair neuroinflammation in a precise and controlled manner.

Transient Interphase Microtubules Appear in Differentiating Sponge Cells

Cells
Microtubules are an indispensable component of all eukaryotic cells due to their role in mitotic spindle formation, yet their organization and number can vary greatly in the interphase.

Nuclear Translocation of S100A9 Triggers Senescence of Human Amnion Fibroblasts by De‐Repressing LINE1 Via Heterochromatin Erosion at Parturition

Advanced Science, EarlyView.
This study shows that the classical secretory protein S100 calcium‐binding protein A9 (S100A9) can translocate to the nucleus upon de‐phosphorylation at Thr 113 in human amnion fibroblasts at parturition, where S100A9 induces heterochromatin erosion through segregation of the heterochromatin maintenance protein, resulting inLong Interspersed Nuclear ...

N‐acetyltransferase 10 promotes colon cancer progression by inhibiting ferroptosis through N4‐acetylation and stabilization of ferroptosis suppressor protein 1 (FSP1) mRNA

Cancer Communications, Volume 42, Issue 12, Page 1347-1366, December 2022., 2022
Abstract Background N‐acetyltransferase 10 (NAT10) is the only enzyme known to mediate the N4‐acetylcytidine (ac4C) modification of mRNA and is crucial for mRNA stability and translation efficiency. However, its role in cancer development and prognosis has not yet been explored.

Engineering the Immune Response to Biomaterials

Advanced Science, EarlyView.
This paper reviews immune responses to biomaterials, stages of evolution in relation to managing these responses ranging from preventing to modulating them. It also discusses state‐of‐the‐art strategies to modulate these responses and modes of their delivery.

Curvature-sensitive kinesin binding can explain microtubule ring formation and reveals chaotic dynamics in a mathematical model [PDF]

arXiv, 2018
Microtubules are filamentous tubular protein polymers which are essential for a range of cellular behaviour, and are generally straight over micron length scales. However, in some gliding assays, where microtubules move over a carpet of molecular motors, individual microtubules can also form tight arcs or rings, even in the absence of crosslinking ...

Mitigating Doxorubicin‐Induced Cardiotoxicity and Enhancing Anti‐Tumor Efficacy with a Metformin‐Integrated Self‐Assembled Nanomedicine

Advanced Science, EarlyView.
A novel self‐assembled nanomedicine (PMDDH) has been developed for the co‐delivery of doxorubicin and metformin, aiming to enhance the anti‐tumor efficacy of doxorubicin while alleviating its cardiotoxicity through the activation of cGAS‐STING and AMPK signaling pathways, respectively.
