Radiation response of mammalian cells grown in culture. 1. Repair of X-ray damage in surviving Chinese hamster cells.

Radiation Research, 1960
The generally observed threshold type of response of the lethal effect of x rays on cultured mammaliam cells means that damage must be accumulated before a lethal response is prcduced. Surviving cells are, therefore, damaged cells. A study was undertaken,

Dominant white spotting in the Chinese hamster

Journal of Heredity, 1987
An autosomal dominant white spotting mutant is described for the Chinese hamster. The mutant gene is designated as dominant spot (symbol Ds). The homozygote DsDs is a prenatal lethal while the heterozygote Ds + displays white spotting. The expression of white is variable, ranging from a white forehead spot to extensive white on the body.

Carbohydrate Metabolism in Chinese-Hamster Cells [PDF]

Biochemical Society Transactions, 1976
Carbohydrate metabolism has been extensively studied in micro-organisms, animals and plants. The major metabolic routes are well established and many of the enzymes have been extensively purified and studied in vitro. Experiments with whole animals, perfused organs and isolated cells have established an overall picture of the regulation of carbohydrate

Cell engineering and cultivation of chinese hamster ovary (CHO) cells.

Current Pharmaceutical Biotechnology, 2010
Mammalian cell lines are important host cells for the industrial production of pharmaceutical proteins owing to their capacity for correct folding, assembly and post-translational modification.

Asynchronous centromere division in the Chinese hamster

Cytogenetic and Genome Research, 1972
Asynchronous centromere division, i.e., variation in the distance between sister centromeres in the same cell, has been observed in bone-marrow cells of the Chinese hamster (2n = 22). The cells were harvested with brief hypotonic treatment but without colchicine.

Effect of intestinal hyperthermia in the Chinese hamster

International Journal of Radiation Oncology*Biology*Physics, 1984
If hyperthermia is to become a useful cancer therapeutic modality, normal tissue response must be thoroughly understood. The hyperthermia response of Chinese hamster intestine was studied by immersion of the exteriorized small intestine in heated tissue culture medium.

X-ray sensitivity during the cell generation cycle of cultured Chinese hamster cells.

Radiation Research, 1966
Our earlier reports (1–3) have provided a general, qualitative description of the X-ray sensitivity of Chinese hamster cells as a function of their age within the generation cycle. With a partially synchronized cell population and colony survival used as

Infection of the Chinese Hamster with Trichinella pseudospiralis

The Journal of Parasitology, 1989
A mean of 2,862 muscle larvae was recovered on day 45 postinfection (PI) from the total body musculature of Chinese hamsters infected with 498 Trichinella pseudospiralis. Infection of the Chinese hamster with 494 Trichinella spiralis resulted in recovery of a mean of 225 muscle larvae on day 45 PI. The reproductive capacity index for T.

Variation in sensitivity to heat shock during the cell-cycle of Chinese hamster cells in vitro.

International Journal of Radiation Biology and Related Studies in Physics Chemistry and Medicine, 1971
SummaryWhen asynchronous cells were exposed for 4–100 min to heat shocks of 43·5–46·5°c, a sigmoidal relationship between survival and duration of heat treatment was observed.

Heterogeneity in Chinese hamster ribosomal DNA

Chromosoma, 1978
A discrete heterogeneity has been detected in Chinese hamster ribosomal DNA after Eco R1 digestion of total DNA followed by a Southern transfer and hybridization with [125I]18S or [125I]28S ribosomal RNA. Digestion with Eco R1 produces three fragments, 4.3, 6.0 and 9.5 x 10(6) daltons respectively, which hybridize with 18S RNA.
