The 5 tetranucleotide short tandem repeats, HUMTH01, HUMVWA31/A, HUMF13A1, HUMFES/FPS and HUMLPL were studied using different electrophoretic methods and PCR amplification conditions in order to optimize the typing conditions. A genetic population study in the population of Galicia was carried out and the allele and genotype frequencies are given. Compliance with the Hardy-Weinberg equilibrium was tested using different statistical parameters, with clear advantages resulting in favor of using the exact test (Guo-Thompson method) instead of conventional chi-square methods. Some statistical parameters of forensic interest (PD, CE, h) were also calculated. There were no mutations found in a total of 73 paternal meioses and 101 maternal meioses. Abnormal electrophoretic mobility was found in the AT-rich STR HUMF13A1 under non-denaturing conditions and, therefore, the use of denaturing conditions is absolutely necessary. No "stutter" bands were found, although double peaks in the HUMFES/FPS system were observed in some samples. The advantage of using automated sequencers with fluorescent technology is also reported.

A maximum of 6 STR systems (TH01, VWA, ACTBP2, FES, F13B, D21S11) was investigated in 7 human populations (Germans, Turks, Moroccans, Japanese, Chinese, Papuans, Ovambos). In each population no deviations from Hardy-Weinberg equilibrium were observed. Out of each population the phenotypes of 50 individuals (comprising 3 to 6 STRs) were randomly selected. Based on the phenotype frequencies interpopulation comparisons were carried out using the frequencies of each other population. Within major ethnic groups only minor differences in phenotype frequencies were found. Between major ethnic groups differences of up to several orders of magnitude could be observed. The most discriminative STRs for interpopulation comparisons were TH01, FES and F13B.

Lactogens [prolactin (Prl) and growth hormone] stimulate phosphorylation of the 40S ribosomal protein, S6, in Nb2 cells by mechanisms that do not involve participation of cAMP or protein kinase A, protein kinase C, or cGMP-dependent protein kinase. However, inhibition of tyrosine kinase (TK) abrogates Prl-mediated macromolecular biosynthesis. Inasmuch as lactogen signaling may involve sequential activation of protein kinases, the effect of Prl on the well-characterized mitogen-activated protein kinase (MAPK) and S6 kinase (S6K), the enzyme responsible for S6 phosphorylation in vivo, and their relationship to Nb2 macromolecular biosynthesis and mitogenesis were investigated. The results show that MAPK stimulation is transient (peak activity, 30 min) and precedes that of S6K, which reaches a maximum at 1.5-2 h, and slowly returns towards control levels at 6 h. Both staurosporine which inhibits GH receptor-associated kinase (JAK2) and genistein (GEN), an inhibitor of membrane-associated and cytoplasmic TKs, abrogate Prl-stimulated TK, MAPK, and S6K. Rapamycin (RAP), a specific inhibitor of p70S6K, completely blocks S6K but does not affect TK and MAPK. TK and MAPK activity correlates with Prl-stimulated anabolism, i.e., protein and DNA synthesis and mitogenesis. Thus, concentrations of STR and GEN which abrogate TK and MAPK inhibit anabolism virtually 100%. However, RAP, which inhibits S6K (ca. 100%) but not TK or MAPK, only delays Prl-mediated anabolism. These results indicate that Prl signaling in Nb2 cells involves a protein kinase cascade and that regulation of receptor-associated kinase, TK, and MAPK correlates with anabolism. The role of S6K (and S6 phosphorylation) appears to be ancillary.

The allele frequency distributions of four VNTR loci amplified by PCR have been studied in a population of 205 individuals from Spain. The loci analysed are D1S80 and three STRs: HUMTH01, HUMFES/FPS and HUMACTBF2 (SE33). The former was visualized in Metaphor agarose gels, and the STRs in sequencing polyacrylamide gels under denaturing conditions which could separate alleles with differences of a single base. This is of particular importance in the HUMTH01 locus, a tetrameric STR in which two alleles (9.3 and 10) were detected differing in a single base. Furthermore, HUMACTBP2 has at least 30 alleles, some of which may vary by as little as one base. At this locus a variation in the allele mobility was observed, depending on the electrophoretic conditions. For this reason, there should be careful consideration before this marker is accepted and validated as a common interlaboratory system. This paper does not include any comparison of the frequencies obtained for this locus with other recent studies. For the rest of the loci, the frequencies found have been compared with other published population studies; they show a degree of difference, particularly in the D1S80 locus. Finally, the systems were tested for Hardy-Weinberg equilibrium, and some statistical parameters of forensic interest were calculated.

We have examined the performance and reproducibility of an automated DNA profiling system which is based on the multiplex amplification of 4 tetrameric STR loci-HUMVWFA31/A. HUMTH01, HUMF13A1 and HUMFES/FPS. The system was able to type 100 pg of purified, undegraded, genomic DNA. At lower concentrations of DNA (below 100 pg), allelec drop-out occurred due to stochastic differences in allele copy number. Minor variation of individual PCR reagent concentrations or cycling temperatures did not result in a significant effect on the efficiency of amplification of any of the 4 loci in the quadruplex system. More substantial variation of reagent concentrations or cycling temperatures outside the optimum range of the system resulted in a reduction or complete loss of signal for one or more loci. This was also observed at high ionic strength or extreme pH. However, under all reagent concentrations and conditions studied, no artefact bands that could potentially result in the mistyping of a sample were apparent within the read region (130-240 bases) of the gel. Evaluation of both native and denaturing polyacrylamide gels revealed that, although native gels displayed faster run times, the sizing precision of such gels for certain STR loci was lower than that of denaturing gels. Also, artefact bands may be present within the read region of native gels. In conclusion the quadruplex amplification system described, coupled with automated fluorescence-based detection on denaturing polyacrylamide gels, appeared to be a robust and reliable system for individual identification.

Alleles of the STR systems HumFES/FPS, HumVWA and HumD21S11 were sequenced and analyzed. Sequence data revealed 3 different systems concerning the complexity of their sequence structure. HumFES/FPS belongs to the STR polymorphism with a simple repeat structure. Only 2 subtypes were found with a base substitution in the 5'-flanking region and no variation in the repeat region. In the STR system HumVWA the sequence structure of the repeat region is more complex, because 2 tetranucleotide units TCTA and TCTG were present. Additionally allele 14 revealed a completely different sequence structure leading to a different electrophoretic mobility. The repeat region of HumD21S11 is compound in structure. The possibility of variation at 3 positions leads to the occurrence of microheterogeneities in fragments of apparent length. In the upper allele range alleles arise with an additional incomplete TA-repeat.

We report on a Dutch population study of the STR loci HUMTHO1, HUMFES/FPS, HUMVWA31/1, and HUMF13A1, in which we used multiplex amplification and automated fragment detection. Genotype and allele frequencies showed no deviation from Hardy-Weinberg and linkage equilibrium. The improved Bonferroni procedure was used to combine the results of several tests. The power of discrimination of a complete profile exceeded 0.9998. We compared the allele frequencies in the Dutch sample to the frequencies in other populations using a bipilot to visualize alleles and populations simultaneously. The Dutch sample was similar to most other Caucasian samples. The data demonstrate that the genetic systems in this report are a valuable tool for forensic identity testing in The Netherlands.

Population data studies for the three tetranucleotide STR systems HumTH01, HumVWA and FES/ FPS were carried out on a Caucasian population sample from Lower Franconia (Germany). The observed heterozygosities were 0.83, 0.80 and 0.73, respectively, and the discrimination power of the triplex was 0.9995. All loci were in accordance with Hardy-Weinberg equilibrium tested using the chi 2-analysis.

A population study of unrelated individuals from North Poland (Gdansk area) was carried out to investigate the allele distributions of the five STR systems HUMCD4, HUMFES/FPS, HUMVWA31, HUMTH01 and ACTBP2. PCR products were separated on horizontal non-denaturing polyacrylamide gels followed by silver staining. For all STR systems analysed the distribution of observed phenotypes did not deviate from Hardy-Weinberg equilibrium. A comparison of allele distributions between Polish and other European Caucasian population samples is presented.

Experiments were performed to evaluate the efficiency of PCR-STR (Short Tandem Repeats) and PCR-sequence polymorphisms for the identification of stained pap smears and postcoital slides stained with cytological and forensic techniques. HLA-DQA1, PolyMarker, Amelogenin, HUMTH01, HUMVWFA31, HUMF13B, and HUMFES/FPS were determined. With the exception of the forensic Baecchi stain, all the PCR-systems gave consistent results in comparison with the reference blood from the donors. Cytological stained smears can be important evidence for identification in sexual assault cases and in missing person cases.
