Artificial molecular machines and motors—Design and control of nanoscale motion

FEBS Letters, EarlyView.
Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...

Rational design of crystalline two-dimensional frameworks with highly complicated topological structures

Nature Communications, 2019
Constructing two-dimensional (2D) polymers with complex tessellation patterns is important for the fabrication of advanced materials but achieving such complexity is a great challenge.

Translating whole‐genome doubling into precision medicine in cancer

Molecular Oncology, EarlyView.
Whole‐genome doubling creates a WGD‐positive tumor state characterized by persistent chromosomal instability, karyotypic diversification, and cellular stress. These same biological pressures drive aggressive tumor evolution while exposing therapeutic vulnerabilities, providing a rationale for WGD‐informed precision medicine. Whole‐genome doubling (WGD)

Nucleic acid enzymes: The fusion of self-assembly and conformational computing

, 2009
Macromolecules are the predominant physical substrate sup-porting information processing in organisms. Two key characteristics—conformational dynamics and self-assembly properties—render macro-molecules unique in this context.

Targeting transcription factors associated with hemoglobinopathies: Lessons from successful interventions and implications for cancer

Molecular Oncology, EarlyView.
This review summarizes the transcription factors, repressive chromatin‐modifying complexes, and epigenetic mechanisms that control fetal hemoglobin repression. Notably, many regulators of γ‐globin silencing also function in transcriptional and epigenetic networks that drive cancer, highlighting opportunities to translate advances in hemoglobinopathy ...

OrthoID: profiling dynamic proteomes through time and space using mutually orthogonal chemical tools

Nature Communications
Identifying proteins at organelle contact sites, such as mitochondria-associated endoplasmic reticulum membranes (MAM), is essential for understanding vital cellular processes, yet challenging due to their dynamic nature.

ADP‐ribosylation: An emerging regulator of the epigenome

Molecular Oncology, EarlyView.
ADP‐ribosylation has emerged as a dynamic epigenetic signaling mechanism that modifies histones and chromatin‐associated proteins. Through coordinated PARylation and MARylation, it integrates with other histone modifications to regulate chromatin structure, transcription factor activity, and gene expression, influencing genome function and disease ...

Self-Assembly and Biomaterials [PDF]

Nano Letters, 2010
An interesting field within the broad subject of biomaterials is the chemical and physical crafting of materials that can functionally substitute or help regenerate the organs and tissues of the human body. Regeneration is the new dimension of this field as opposed to the more established area of permanent implants and devices to substitute natural ...

Systematic analysis of nucleation-dependent polymerization reveals new insights into the mechanism of amyloid self-assembly [PDF]

, 2008
Self-assembly of misfolded proteins into ordered fibrillar aggregates known as amyloid results in numerous human diseases. Despite an increasing number of proteins and peptide fragments being recognised as amyloidogenic, how these amyloid aggregates ...

Mechanisms and therapeutic opportunities of the ribotoxic stress response in cancer

Molecular Oncology, EarlyView.
Cancer cells' high translational demand creates opportunities to therapeutically target ribosome function. Ribosome stalling and collisions activate ZAKα and the ribotoxic stress response (RSR), which can trigger rapid, p53‐independent apoptosis in cancer.
