Water Science and Technology, 2003 The goal of the research was the development of a simple method to quantify microbial groups in environmental samples. Fluorescence intensity was measured in the sample before and after whole cell fluorescence in situ hybridization with rRNA-targeted, fluorochrome-labeled oligonucleotide probes.

Imaging mass spectrometry of polymeric materials [PDF]
, 2009 Imaging mass spectrometry (MS) is a technique that makes images of molecular distributions at surfaces based on mass spectral information. At a range (typically a raster) of positions, mass spectra are measured from the surface giving a characteristic ...

Interrogating the architecture of protein assemblies and protein interaction networks by cross-linking mass spectrometry [PDF]
, 2015 Proteins are involved in almost all processes of the living cell. They are organized through extensive networks of interaction, by tightly bound macromolecular assemblies or more transiently via signaling nodes.

Oncogenic DMTF1β promotes cancer cell motility by regulating autophagy through ULK1 stabilization
Molecular Oncology, EarlyView.In the current study, we demonstrate that the oncogene DMTF1β regulates ULK1 stability by reducing its proteasomal degradation in cancer cells. This stabilization enables ULK1 to induce autophagy, which in turn facilitates cancer cell migration. Consequently, reduced DMTF1β levels lead to decreased autophagy and impaired cancer cell migration.

Molecular Oncology, EarlyView.Breast cancer remains a major cause of cancer death in women, frequently developing endocrine therapy resistance. This study demonstrates that upregulated p21‐activated kinase 1 (PAK1) activity drives resistance to tamoxifen and long‐term estrogen deprivation in ER+ breast cancer models.
