Lineage-Specific Duplication and Loss of Pepsinogen Genes in Hominoid Evolution
Fourteen different pepsinogen-A cDNAs and one pepsinogen-C cDNA have been cloned from gastric mucosa of the orangutan, Pongo pygmaeus. Encoded pepsinogens A were classified into two groups, i.e., types A1 and A2,...

Topic 2: Fatty Acid Content of the Plants Consumed by Japanese Macaques
The dietary crude fat content consumed by wild Japanese macaques (Macaca fuscata) has previously been measured from the point of view of energy balance (Iwamoto 1982; Nakagawa 1989; Soumah and Yokota 1991). Howe...

Comparative analysis of estrogen receptor gene polymorphisms in apes
Polymorphic microsatellite repeats in the promoter region of estrogen receptor α gene (ESRα and the intron 6 region of estrogen receptor β gene (ESRβ) have been reported in human populations. To examine the evolu...

Wild chimpanzee infant urine and saliva sampled noninvasively usable for DNA analyses
In many genetic studies on the great apes, fecal or hair samples have been used as sources of DNA. However, feces and hairs are difficult to collect from chimpanzee infants under 3 years of age. As alternative...

Comparison of androgen receptor CAG and GGN repeat length polymorphism in humans and apes
Two polymorphic trinucleotide repeats of human androgen receptor gene (hAR), CAG and GGN which encode glutamine and glycine, have been shown to be associated with human diseases. The number of repeats ranges from...

How costly are ejaculates for Japanese macaques?
Much sexual selection theory is based on the idea that ejaculate is cheap. Since further details are unknown our aim was to determine the energy that primate males require for ejaculate production. We addresse...

Molecular Evolution of the Periphilin Gene in Relation to Human Endogenous Retrovirus M Element
HERV-M (human endogenous retrovirus M), related to the super family of HERV-K, has a methionine (M) tRNA primer-binding site, and is located within the periphilin gene on human chromosome 12q12. HERV-M has bee...

Genetic diversity among African great apes based on mitochondrial DNA sequences
The mitochondrial DNA D-Loop region was sequenced, analyzed and used as a molecular marker for populations of chimpanzee (Pan troglodytes), bonobo (P. paniscus) and gorilla (Gorilla gorilla and G. beringei), and ...

Species and sex identification of western lowland gorillas (Gorilla gorilla gorilla), eastern lowland gorillas (Gorilla beringei graueri) and humans
Methods for the identification of the sex and species of individuals from samples non-invasively taken from humans and gorillas were established. Amplification of a segment of amelogenin (AMG), which is an X–Y...

A prevalent POLG CAG microsatellite length allele in humans and African great apes
The human nuclear gene for the catalytic subunit of mitochondrial DNA polymerase γ (POLG) contains within its coding region a CAG microsatellite encoding a polyglutamine repeat. Previous studies demonstrated an a...

Comparative study of urinary reproductive hormones in great apes
Urinary estrone conjugates (E1C), pregnanediol-3-glucuronide (PdG), and follicle-stimulating hormone (FSH) were determined by enzyme immunoassays (EIAs) during the normal menstrual cycle in the orangutan, gorilla...

Behavioral evidence of color vision deficiency in a protanomalia chimpanzee (Pan troglodytes)
Although color vision deficiency is very rare among Old World monkeys and apes, one male chimpanzee (Lucky) was identified as protanomalous by genetic and physiological analyses. This study assessed behavioral...

Polymorphic Variations in Long- and Middle-Wavelength-Sensitive Opsin Gene Loci in Crab-Eating Monkeys
Old World primates have trichromatic color vision as a result of three types of cone opsin, each of which is maximally sensitive to either short (S), middle (M), or long (L) wavelengths. Most color vision defe...

Genetic mechanism and property of a whole-arm translocation (WAT) between chromosomes 8 and 9 of agile gibbons (Hylobates agilis)
C-banding analysis with 47 gibbons of the subgenus Hylobates (Hylobates) (44-chromosome gibbons) uncovered that the gibbons had a characteristic complicated C-banding pattern. The C-band pattern also revealed tha...
