The C. elegans ninein homolog NOCA-1 is important for the assembly of non-centrosomal microtubule arrays required for embryo production, nuclear positioning and larval development.

C. elegans germline stem cells become quiescent under starved conditions, and this quiescence maintains the stem cell state even in the absence of GLP-1/Notch signaling, which is otherwise essential for stem cell maintenance.

The immune system in the vagina becomes more active when young women begin to have sexual intercourse, and this immune activity could influence the risk of acquiring sexually transmitted infections.
