Spatial biology in cancer epigenetics

Molecular Oncology, EarlyView.
Spatial epigenomics combines molecular profiling with tissue architecture to reveal how gene regulation is organized within intact tissues. In cancer, these technologies uncover the mechanisms driving tumor heterogeneity and microenvironmental interactions, opening new opportunities for biomarker discovery and precision medicine.

Magnetic domain wall skyrmions

Physical Review B, 2019
It is well established that the spin-orbit interaction in heavy metal/ferromagnet heterostructures leads to a significant interfacial Dzyaloshinskii-Moriya Interaction (DMI) that modifies the internal structure of magnetic domain walls (DWs) to favor Néel over Bloch type configurations.

Antiferromagnetic domain wall creep driven by magnetoelectric effect

APL Materials, 2018
We observed the magnetoelectric induced domain wall propagation in a Pt/Co/Au/Cr2O3/Pt stacked thin film based on magnetic domain observations using scanning soft X-ray magnetic circular dichroism microscopy.

Somatostatin receptor 4 (SSTR4) is a tumor suppressor in cutaneous and head & neck squamous cell carcinomas

Molecular Oncology, EarlyView.
This study identifies somatostatin receptor 4 (Sstr4) as a critical tumor suppressor against skin and head/neck cancers (HNSCC, cSCC, and BCC). The loss of Sstr4 removes a check on cell growth, causing hyperactivation of the MAPK‐ERK signaling pathway (↑).

Domain structure and magnetic properties of terbium ferrite-garnet in the vicinity of the magnetic compensation point

Eurasian Physical Technical Journal, 2019
The domain structure of a thin single crystal plate of the iron garnet Tb3Fe5O12 has been investigated using the magneto-optical method in the temperature range near the magnetic compensation point of this ferrimagnet Tc = 248.6 K.

Paclitaxel induces NM2‐dependent cellular contraction through GEF‐H1 dissociation from microtubules and RhoA/ROCK activation in cancer cells

Molecular Oncology, EarlyView.
Taxanes are widely used chemotherapeutics whose effects on cellular mechanics remain poorly understood. We show that paclitaxel induces rapid cellular contraction by promoting GEF‐H1 dissociation from microtubules and non‐muscle myosin II activation through RhoA/ROCK.

Design, fabrication, and characterization of magnetic nanostructures

, 2008
For several years, thin films of ferromagnetic materials with metallic spacer layers showing giant magnetoresistance (GMR) were the technological basis used in the read-heads of hard disk drives. Similarly, tunnelling magnetoresistance (TMR), which is an
