Rab31 expression levels modulate tumor-relevant characteristics of breast cancer cells.

Background: Rab proteins constitute a large family of monomeric GTP-binding proteins that regulate intracellular vesicle transport. Several Rab proteins, including rab31, have been shown to affect cancer progression and are related with prognosis in various types of cancer including breast cancer. Recently, the gene encoding rab31 was found to be overexpressed in estrogen receptor-positive breast cancer tissue.

Pilot trial of cyclosporine 1% ophthalmic ointment in the treatment of keratoconjunctivitis sicca.

This trial was a randomized, double-masked, crossover study during which patients with keratoconjunctivitis sicca underwent 6 weeks of treatment with either cyclosporine 1% ophthalmic ointment or placebo followed by 6 weeks of the alternative treatment. Washout periods using only unpreserved artificial tears preceded both treatment cycles. Twenty-five patients completed the first treatment period, but only eight met entry criteria for period II.

Safety and tolerability of two percent cyclosporine (Sandimmune) ophthalmic ointment in normal volunteers.

Thirty-six healthy male volunteers were enrolled in two sequential double-masked, placebo-controlled trials with the objective of assessing the safety and local tolerability of 2% cyclosporine ophthalmic ointment. Subjects were randomly assigned to active or placebo groups and dosed once, twice, or thrice daily for 14 days. Safety and tolerability were assessed through patient interviews, ophthalmologic examinations, routine laboratory testing, and blood cyclosporine assays.
