The PTEN (phosphatase and tensin homolog deleted on chromosome 10) tumour suppressor is mutated in 40–50% of human endometrial cancers. PTEN exerts its effects in part via inhibition of the antiapoptotic protein AKT. We demonstrate that two endometrial cancer cell lines that harbour PTEN mutations, Ishikawa and RL95-2, have high levels of phosphorylated AKT and high AKT kinase activity. Two additional endometrial cancer cell lines that express wild-type PTEN, Hec1A and KLE, have little phosphorylated AKT and minimal demonstrable AKT kinase activity. We tested a potential inhibitor of the AKT pathway, API-59CJ-OMe, in these four cell lines. We found that API-59CJ-OMe inhibits AKT kinase activity and induces apoptosis in the Ishikawa and RL95-2 cell lines with high AKT activity, but has little effect on Hec1A and KLE cells without AKT activity. API-59CJ-OMe may therefore have therapeutic potential for those endometrial cancers that harbour PTEN mutations and AKT activation.

Female fertility declines dramatically with age, and childbearing at older maternal ages has significant medical consequences for mother and infant that are well-known to health professionals. Despite this, the average maternal age in the United States continues to rise. Many factors likely contribute to this secular trend; to date, no research has examined whether American women are aware of the complications of deferring conception and how this correlates with health literacy. The purpose of this study was to evaluate women's knowledge of the implications of delaying pregnancy. A structured, in-person interview was administered to 300 women between 20 and 50 years of age attending 1 of 2 gynecologic clinics at a single institution. Demographic information, medical history, and gynecologic history were obtained; and participants answered questions about the implications of aging for fertility and pregnancy outcome. Health literacy and numeracy were assessed. Participants demonstrated knowledge deficits about the implications of aging on fertility and pregnancy, and many were unfamiliar with success rates of infertility treatments. Several demographic factors correlated with knowledge; health literacy and numeracy were both important predictive variables. To the authors' knowledge, this is the first study of women's knowledge about fertility, aging, and their health literacy. Awareness of the importance of health literacy and numeracy should inform future educational efforts about fertility.

Recurrent OASIS occurred in a small percentage of women (3.2%) who subsequently delivered vaginally. Recurrent OASIS was associated with operative vaginal delivery and birth weight 4000 g or greater. Neither episiotomy at first delivery nor at subsequent delivery conferred an increased recurrence risk.
