Investigations on Zinc Isotope Fractionation in Breast Cancer Tissue Using in vitro Cell Culture Uptake-Efflux Experiments

Frontiers in Medicine, 2022
Zinc (Zn) accumulates in breast cancer tumors compared to adjacent healthy tissue. Clinical samples of breast cancer tissue show light Zn isotopic compositions (δ66Zn) relative to healthy tissue. The underlying mechanisms causing such effects are unknown.

Fractionation of Hepatic Nonparenchymal Cells [PDF]

The Scientific World JOURNAL, 2002
The majority of parenchymal cells from mammalian liver cells can be removed by very low speed centrifugation (50 g) but a simple low-density barrier (1.096 g/ml) is required to remove the remaining parenchymal cells from the 50-g supernatant which contains all of the lower density nonparenchymal cells.

Separation of blood cells with differing deformability using deterministic lateral displacement [PDF]

, 2014
Determining cell mechanical properties is increasingly recognized as a marker-free way to characterize and separate biological cells. This emerging realization has led to the development of a plethora of appropriate measurement techniques. Here, we use a

Polysome profiling followed by quantitative PCR for identifying potential micropeptide encoding long non-coding RNAs in suspension cell lines

STAR Protocols, 2022
Summary: Micropeptides are emerging as important regulators of various cellular processes. Long non-coding RNAs (lncRNAs) serve as a source of micropeptide-encoding small reading frames. The techniques to detect micropeptides or translating lncRNAs, such
