The presence of a soluble specific antigen serologically identical with an antigen found in HeLa cells has been shown in 31 per cent of human malignancies. Similar material has not been isolable from nonmalignant adult or fetal human tissues. Ac cording to the accumulated statistical data, there seems to be no correlation between the degree of malignancy of the diseased tissue and the presence ...

A facile alcoholysis of 7-methoxymitosanes and 5-methoxyindolequinone under basic conditions was discovered and a series of 7-alkoxymitosanes were synthesized from mitomycins A and B using this reaction. They showed strong antibacterial activity against various Gram-positive and Gram-negative bacteria and were potent inhibitors of cultivating HeLa S-3 cells in vitro. Among them, 7-n-propoxy-7-d...

The objective of this study was to the synergistic antitumor effect lipophilic bismuth nanoparticles (BisBAL NPs) with antibiotic solution Neo-Poly gramicidin on human cervical tumor cells. BisBAL NPs and cancer cell line (HeLa) determined by MTT viability assay fluorescence microscopy. After a 24-h exposure 0.1× HeLa growth decreased 94%. Fluorescence microscopy confirmed death higher among tr...

• Quinoline-based BODIPYs as potential EGFR/VEGFR-2 inhibitors. Lipinski's drug likeness of compounds 1–3 revealed promising physicochemical properties for oral bioavailability. The interaction was examined by molecular docking with binding energies in the order 3˃2˃1. HOMO and LUMO were also calculated using DFT method. vitro anticancer activity 1 3 on HeLa cells evaluated. This paper reports ...

Purpose: To delve into the related molecular mechanism of suppressor cytokine signaling 4 (SOCS4) on cervical cancer cell proliferation and migration. Methods: Quantitative real-time polymerase chain reaction western blot assays were employed to examine SOCS4 mRNA or protein expression in four human line (HeLa, SW-732, AV3, CaSki) normal epithelium immortalized (H8) MTT viability applied verify...

Drug delivery by folate conjugated amphiphiles Abstract A series of amphiphilic conjugates of folic acid and aliphatic fatty acids was designed to serve as targeted drug delivery carriers for anticancer agents. The effectiveness of targeted delivery of amphiphile was evaluated using folate receptor positive HeLa cells and Caco-2 cells that do not express folate receptor. Wild type HeLa cells we...

The interaction between tumor cells and surrounding normal cells is very important in the prognosis of tumors. The object of this study was to determine the effect of recipient bed of tumor xenograft on tumor metastasis using a novel parotid gland tumor model. HeLa cells were xenografted into the parotid gland or subcutaneous tissues of athymic mice. Eight weeks after the transplantation, all m...

A method for the preparation of HeLa cell plasma membrane ghosts is described. The purity of the plasma membrane fraction was examined by phase contrast and electron microscopy, by chemical analysis, and by assay of marker enzymes. Data on the composition of the plasma membrane fraction are given. It was observed that the distribution pattern of 5'-nucleotidase activity among the subcellular fr...

Free and informed consent of participants in research studies is a cornerstone of biomedical research, but this has not always been the case. Cells derived from tumor tissue of an American woman without her consent more than 60 years ago and named HeLa cells were eventually identified as belonging to Henrietta Lacks, a fact that became widely known in 2010 upon publication of a bestselling book...

Seven strains of HeLa cells have been characterized by the number of chromosomes and the activity of the enzymes alkaline phosphatase, glucose-6-phosphate dehydrogenase, 6-phosphogluconic dehydrogenase, and lactic dehydrogenase. All seven strains were found to differ as to chromosome numbers and enzyme levels despite the fact that two strains were called HeLa and three were called HeLa S3. Thre...
