Female hormone receptors are differentially expressed in mouse fibrocartilages.

ABSTRACT:

Objective

Despite the female predilection for joint diseases, and the known effects of female hormones in regulating chondrocyte function, the various female hormone receptor subtypes in joints are not well characterized, and comparisons in receptor profiles between joints and genders are lacking. This investigation characterized and compared the relative levels of estrogen receptors (ER)-alpha and -beta, relaxin receptors LGR7 and LGR8, and progesterone receptor (PR) in the temporomandibular joint (TMJ) disc, knee meniscus (KM) and pubic symphysis fibrocartilages.

Methods

Fibrocartilaginous cells from 12-week-old mice were maintained in serum-containing alpha-modified Eagle's medium (MEM) until confluence. Total RNA and cell lysates were assayed by RT-PCR, qRT-PCR, immunocy
