An isoform of 14‐3‐3 protein regulates transbilayer lipid movement at the plasma membrane
FEBS Letters, EarlyView.Loss of 14‐3‐3ζ in CHO cells confers resistance to exogenous phosphatidylserine (PS) and impairs endocytosis‐independent inward flip‐flop of fluorescent PS at the plasma membrane. RNAi‐mediated knockdown reproduces this defect, while no additive effect is seen in ATP11C‐deficient cells.

Chemiluminescent Measurement of Telomere DNA Content in Biopsies
BioTechniques, 2002 Telomeres are nucleoprotein complexes that protect the ends of chromosomes from fusion and degradation. They are typically shorter in tumor cells than in paired normal cells, and shorter telomeres are associated with poor outcome in cancer. We previously

Entamoeba shows reversible variation in ploidy under different growth conditions and between life cycle phases. [PDF]
PLoS Neglected Tropical Diseases, 2008 Under axenic growth conditions, trophozoites of Entamoeba histolytica contain heterogenous amounts of DNA due to the presence of both multiple nuclei and different amounts of DNA in individual nuclei.

The human gut microbiome across the life course
FEBS Letters, EarlyView.Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

Journal of the American Society for Horticultural ScienceFlow cytometry has been widely used to estimate relative and absolute genome sizes (DNA contents) of plants for more than 50 years. However, the accuracy of these estimates can vary widely because of many factors, including errors in the genome size ...

Measurement of Telomeric DNA Content in Human Tissues
BioTechniques, 1997 Telomeres, nucleoprotein complexes at the ends of eukaryotic chromosomes, are 10–12 kbp in length in somatic cells, but as small as 1–2 kbp in rapidly growing cancer cells.

FEBS Letters, EarlyView.This study reveals that the small GTPase Rab14 is necessary for human papillomavirus (HPV) infection and plays an essential role in the transport of virions to the trans‐Golgi network (TGN). HPV in the early endosome (EE), which harbors GTP‐bound Rab14, is transported to the TGN through the switch of Rab14 from its GTP‐bound to GDP‐bound form.

Significance of DNA Content in Oral Carcinoma
The International Journal of Biological Markers, 1989 Standard cytophotometric measurement of DNA in normal, leukoplakic and cancerous oral and oropharyngeal tissues with a Leitz Weitzler Aristophot Cytophotometer showed both 1% and 5% significance in different grades of malignancy and 5% as regards sites ...

FEBS Letters, EarlyView.We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...
