Mitochondrial Ribosomes in HeLa Cells
Nature New Biology, 1971HeLa cell mitochondria contain 60S ribosomes which seem to consist of subunits of 45S and 35S particles. The 16S and 12S RNA components are coded by mitochondrial DNA.

Publisher Summary HeLa cells are not so fastidious concerning medium, and many kinds of media with different components have been used for the genetic study of HeLa cells. HeLa cells grow in a defined medium, such as Ham's F12 medium supplemented with insulin, transferrin, hydrocortisone (aldosterone), fibroblast growth factor, and epidermal growth ...

Chemical Toxicity on HeLa Cells
Current Medicinal Chemistry, 2006HeLa cells were named for Henrietta Lacks, who died in 1952 from an infection of a special type of cancer. Margaret Gey, her physician, started working with these cancer cells that are still used for medical research. In the present review, an attempt has been made to collect the data for the effects of different chemicals on HeLa cells and to discuss ...

Archiv f�r die gesamte Virusforschung, 1965
A strain of varicella virus was isolated and easily maintained in HeLa cells. The infection could be passed with live cells only, practically all infectivity being destroyed by disruption of the cells with sonication or repeated freeze-thawing, even if precautions were taken to favour the infectivity of nucleic acids.

Photodynamic Effects of Pterin on HeLa Cells
Photochemistry and Photobiology, 2011AbstractPterins, heterocyclic compounds widespread in biological systems, participate in relevant biological processes and are able to act as photosensitizers. In the present study, we ascertained that 2‐aminopteridin‐4(3H)‐one, abbreviated as Ptr, is readily incorporated into and/or onto cervical cancer cells (HeLa) and that these cells die upon UV‐A ...

Occurrence of the Crabtree effect in HeLa cells
Cell Biochemistry and Function, 1998The occurrence of a Crabtree effect in HeLa cells was detected. Some properties of pyruvate kinase (PK) were also evaluated. Hexose phosphate, triose-phosphate and phosphoenolpyruvate (PEP) significantly decreased the oxygen consumption of digitonin-permeabilized HeLa cells, which were oxidizing succinate.

Regulation of metallothionein production in HeLa cells
Toxicology Letters, 1991Metallothioneins are cysteine-rich, heavy-metal-binding proteins which have been assumed to participate in the detoxification of toxic metals. The mechanism of thionein (apoprotein of metallothionein) induction by cadmium was studied using cultured human cells.

The assembly of ribosomes in HeLa cells
Journal of Molecular Biology, 1966The assembly of proteins and RNA into a mature ribosome has been studied in the HeLa cell by examining the appearance of labeled ribosomal proteins on mature ribosomes after a pulse of radioactive amino acids followed by a chase with cold amino acids. The ribosomal proteins continue to appear as part of cytoplasmic ribosomes for a period of two hours ...

Mycoplasma fermentans—HeLa Cell Interactions
Clinical Infectious Diseases, 1993A survey of previous evidence for the intracellular localization of mycoplasmas within nonphagocytic cells indicated that it was insufficient to conclude unequivocally that such localization occurred. Illustrations of the seemingly intracellular existence of Mycoplasma fermentans in the tissues of patients with AIDS and other patients rekindled ...

Methylation of ribosomal proteins in HeLa cells
Archives of Biochemistry and Biophysics, 1976Abstract Methylated amino acids from both 40 and 60S subunit proteins of HeLa cytoplasmic ribosome were analyzed. It was observed that methylation of ribosomal proteins occurs in both subunits with N G , N G -dimethylarginine as the major methylated amino acid.
