Chinese hamster genome database: an online resource for the CHO community at www.CHOgenome.org.

Biotechnology and Bioengineering, 2012
The Chinese hamster genome database (http://www.chogenome.org/) is an online resource for the Chinese hamster (Cricetulus griseus) and Chinese hamster ovary (CHO) cell communities.

Cyclophosphamide treatment of prediabetic Chinese hamsters

Acta Physiologica Scandinavica, 1984
To assess the immune system's involvement in the causation of diabetes in the genetically diabetic Chinese hamster, “prediabetic” animals were immunosuppressed with Cyclophosphamide, starting several weeks prior to the expected onset of hyperglycemia. The immunosuppressant dose was titrated to maximally depress the lymphocyte count without significant ...

Ultrastructural study of the adenohypophysis of the Chinese hamster

Cells Tissues Organs, 1976
The adenohypophysis of normal Chinese hamsters of both sexes was examined ultrastructurally. Organs were fixed by intravascular perfusion with S-collidine-buffered glutaraldehyde solution. Seven types of cells were differentiated and, according to morphological characteristics, classified as (1) mammotropes, with very large (400–800 nm) and ...

Gametes and fertilization in the Chinese hamster

Gamete Research, 1983
AbstractFreshly ovulated eggs are each surrounded by a compact cumulus oophorus. The overall diameter of the normal egg (including the zona pellucida) is about 100 μm. Cumulus cells, particularly those near the egg, are arranged redially in a viscous noncellular matrix. The spermatozoon is about 250 μm in length.

Superovulation in immature and mature Chinese hamsters

Gamete Research, 1987
AbstractMature female Chinese hamsters ovulate an average of 8.8 ± 1.0 (mean ± SD) eggs per female in each estrous cycle. Superovulation can be induced in both immature and mature females by subcutaneous or intraperitoneal injections of pregnant mare serum gonadotropin (PMSG) and either human chorionic gonadotropin (hCG) or pituitary luteinizing ...

Conserved microRNAs in Chinese hamster ovary cell lines.

Biotechnology and Bioengineering, 2011
MicroRNAs (miRNAs), a class of short (20-24 nt) non-coding RNAs that direct post-transcriptional repression of messenger RNAs, increasingly have been shown to play a key role in regulating cellular physiology.

Distribution of DNA in Chinese hamster cells

Experimental Cell Research, 1967
Abstract The distribution of DNA in the nucleus of Chinese hamster cells growing in vitro was studied by labeling DNA with tritiated thymidine before cutting 20–25 serial sections through the nucleus. Autoradiography and light microscopy were used to locate the distribution of label in each section.

Cytotoxicity of PAMAM, PPI and maltose modified PPI dendrimers in Chinese hamster ovary (CHO) and human ovarian carcinoma (SKOV3) cells

, 2012
Characterization of dendrimers as potential therapeutics or drug carriers is complete only when toxicity is assessed. There are numerous studies on the influence of surface modification of PAMAM and PPI dendrimers on their cytotoxic properties but ...

PHOTODYNAMIC INACTIVATION OF CHINESE HAMSTER CELLS

Photochemistry and Photobiology, 1983
Abstract— Visible light exposures have been shown to kill acriflavine bound Chinese hamster cells. Such killing was enhanced when (a) dye was present in the medium during irradiation and (b) the pH of the medium was 8.5, instead of the normal 7.5 during the exposure.

Cricetulus griseus (Chinese hamster) [PDF]

, 1967
The long arm of the X may show a weak secondary constriction at the distal third. However, without autoradiography with tritiated thymidine, the X may be indistinguishable from chromosomes No. 4. The Y chromosome is morphologically unique.
