Polar Molecular Organisation in Liquid Crystals [PDF]

, 2003
Various possibilities of polar self-organisation in low molar mass nematic, smectic and columnar liquid crystals are discussed with particular focus on the underlying molecular symmetries and interactions.

Reciprocal control of viral infection and phosphoinositide dynamics

FEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

The epigenetic circle: feedback loops in the maintenance of cellular memory

Epigenetics & Chromatin
The memory of gene expression states, active or repressive, is a fundamental biological concept as it controls cell fate in development, immunity and abiotic stress responses.

Molecular mechanisms of parturition

Infectious Diseases in Obstetrics and Gynecology, 1997
The initial signal for triggering human parturition might be fetal but of trophoblastic origin. Concomitantly, this placental signal would have as its target not only the uterus but also the fetus by activating its hypothalamo-pituitary-adrenocortical axis.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

TUBB4B Downregulation Is Critical for Increasing Migration of Metastatic Colon Cancer Cells

Cells, 2019
Tumor metastasis, the major problem for clinical oncology in colon cancer treatment, is linked with an epithelial-mesenchymal transition (EMT). The observed cellular transformation in this process is manifested by cell elongation, enhanced cell migration

Desorption From Interstellar Ices

, 2007
The desorption of molecular species from ice mantles back into the gas phase in molecular clouds results from a variety of very poorly understood processes.

Energy migration in molecular assemblies:The characterisation and differentiation of two-photon mechanisms [PDF]

, 2006
Energy migration between chromophores plays a prominent role in a range of energy harvesting assemblies. Recent advances in the design and production of light-harvesting polymers have led to the synthesis of novel two-photon absorbing dendrimers.

Photocarcinogenesis-molecular mechanisms

Collegium antropologicum, 2007
The carcinogenicity (photocarcinogenicity) of sunlight to human skin has been recognized more than a century ago. Last decades numerous experimental studies show that UV rays damage DNA, cause gene mutations leading to the development of malignant tumors such basal cell carcinomas, squamous cell carcinomas and melanomas.

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

FEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.
