    Notes: Human monocyles release cytostatic protein factors (CF) upon activation with lymphokines und lipopolysacchairide. CF has been purified from monocyte supernatants by ion-exchange chromatography. chromatofocusing and gel filtration, and this resulted in a 10,000-fold reduction in the amount of protein in the purified CF preparation compared to the amount in the monocyte supernatant. About 5% of the eytostatic activity was recovered after purification. CF constitutes a population of proteins heterogeneous with respect to ionic charge and differing in their isoelectric points, since CF eluted as a broad peak both upon ion-exchange chromatography and chromatofocusing. The isoelectric points of the CF proteins were determined by chromatofocusing to be between 6.0 and 5.0. The molecular weight of CF as determined by gel filtration was in the range of 45,000 to 35,000 daltons. Only one monocyte-secreted protein with a molecular weight of 40,000 was detected upon sodium dodecyl sulphate-polyacrylamide gel electrophoresis of proteins in the purified CF preparations obtained after the final gel filtration step, und this protein may consequently be CF. If the 40,000-dalton protein is CF. one may estimate that about 106 monocytes produced roughly 0.1 μg CF upon activation and that significant cytostasis may be detected with less than nanogram quantities of CF.

    Notes: Human lymphokine-activated monocytes release a cytotoxic protein factor (CF). The cytostatic activity of CF was potentiated by the DNA and RNA synthesis inhibitors actinomycin D, daunomycin, and mitomycin C. These inhibitors increased the sensitivity for detecting CF approximately 10-fold, and this is of great practical value when assaying CF. The CF-potentialing inhibitors had a similar effect on the cell cycle distribution in that they all induced an accumulation of cells in the S and G2 phases of the cell cycle. Cytolytic activity was shown to be associated with CF, and this activity was also greatly potentiated by daunomycin and actinomycin D. The two other inhibitors studied, cycloheximide and 5-fIuorouracil (5-FU), had an adverse effect on the cytostatic activity of CF. These two inhibitors reduced the sensitivity of the assay for CF about fivefold. Cycloheximide had no apparent effect on the relative cell cycle distribution, whereas 5-FU induced an accumulation of cells in the G1 phase. Of the inhibitors studied, only those that induced an accumulation of cells in the S and G2 phases of the cell cycle potentiated the cytotoxic activity of CF. suggesting that CF may preferentially act in these parts of the cell cycle.

    Notes: Summary A family in which an interstitial deletion of the X chromosome, del(X)(q13q21.3), is segregating was ascertained through a boy with cleft lip and palate, agenesis of the corpus callosum, and severe mental retardation. The possible causal relationship to his chromosome abnormality is discussed. Although the deletion occurred within the critical region, the mother showed no signs of gonadal dysgenesis. A phenotypically normal daughter was, as her mother, monosomic for this region of the X, and both showed random inactivation of the X chromosome.

    Notes: Summary Choroideremia is an X-linked hereditary retinal dystrophy leading to blindness in early adulthood. RFLP analyses in three Danish families were consistent with close linkage between choroideremia and the locus DXYS1, located at Xq13–Xq21. Measurable linkage was found between choroideremia and DXS17, at Xq22. Furthermore, choroideremia was diagnosed in a boy with an interstitial deletion at Xq13–Xq21, strongly suggesting the assignment of the locus for choroideremia to this region of the X chromosome. The deletion also covered DXYS1, but did not include DXS17.

    Notes: A procedure is described for isolating milligram quantities of bovine and porcine zonae pellucidae, uncontaminated by follicle cells or their processes. On SDS-polyacrylamide gel electrophoresis the isolated bovine zona material formed one major glycoprotein band with an estimated molecular weight of approximately 100,000 daltons and two minor lower molecular weight components. The isolated pig zonae formed only one glycoprotein band with a molecular weight of approximately 62,000 daltons. Rabbit antisera raised against the isolated zonae were zona-specific and formed only a single precipitin line against the heat-solubilized zonae on immunoelectrophoresis. An adjuvant was not required for high-antibody titers. High titers were also obtained by injection of the dog and rhesus monkey. Anti-zona antibody was detected by immunofluorescence, zona-coating, double-immunodiffusion, and the inhibition of spermbinding to eggs, including those of human origin. Antigenic and sperm receptor properties were stable at 100°C for five minutes, but some activity was lost after longer exposure. The serum antibody produced by rabbits immunized with pig zonae was predominantly IgG and cross-reacted with the zonae of a variety of other species, including primates. Pregnancy was inhibited in female rabbits immunized with pig zona preparations.
