Mechanistic aspects of fluorescent gold nanocluster internalization by live HeLa cells.
Nanoscale, 2013We have studied cellular uptake of ultrasmall fluorescent gold nanoclusters (AuNCs) by HeLa cells by confocal fluorescence microscopy in combination with quantitative image analysis.

Parasynchronous division of HeLa cells
Experimental Cell Research, 1959Abstract It has been observed that populations of human cervical carcinoma cells (strain HeLa) may be induced to undergo parasynchronous division by chilling of the cell culture for a short period. Replicate cultures of HeLa cells were incubated at 37 °C for 24 hours after subculture and then placed at 4 °C for 1 hour.

Anticancer activity and mechanism of juglone on human cervical carcinoma HeLa cells.
Canadian Journal of Physiology and Pharmacology, 2012Induction of apoptosis in tumor cells has become the major focus of anti-tumor therapeutics development. Juglone, a major chemical constituent of Juglans mandshurica Maxim, possesses several bioactivities, including anti-tumor. In the present study, HeLa

Investigating heterogeneity in HeLa cells [PDF]
Nature Methods, 2019 Multi-omic study uncovers biological variation across 14 HeLa cell samples, which might help to explain the growing concerns about reproducibility issues in cell culture.

The biotin requirement of HeLa cells
Journal of Cellular Physiology, 1981AbstractWe have examined the effect of alterations in the biotin content of the medium on the growth, viability, biotin content, and the activities of biotin‐dependent and biotin‐independent enzymes of the HeLa cells. The inclusion in the growth medium of avidin, which almost irreversibly binds with biotin (Kd, 10−15 M), results in an increase in ...

Ribosome Assembly in Hela Cells
Nature, 1972The 80S nucleolar particles have been found to contain peptides characteristic of 30S as well as 50S ribosomal subunits. This lends support to the idea that the maturation of both types of subunits stems from this 80S particle.

MITOCHONDRIAL PROTEIN SYNTHESIS IN HeLa CELLS [PDF]
Acta Endocrinologica, 1973 ABSTRACT HeLa cell mitochondrial polysomes, estimated to consist of two to seven 60S monomers, exhibit an unusual resistance to RNase and EDTA, possibly related to the strongly hydrophobic nature of their polypeptide products which makes the nascent chains particularly "sticky".

A simple assay based on electrochemical impedance spectroscopy (EIS) for detection of telomerase activity is developed, and it is demonstrated that the label-free EIS method is capable of detecting the telomerase activity in HeLa cells with a detection ...

The cytotoxic action of chemicals which transfer electrons from biological reductants to molecular oxygen is believed to result from the formation of •O2-, H2O2, and •OH. Paraquat is one such agent which appears to act in Escherichia coli primarily by generating •O2-, but necessarily H2O2 as well.
