Abstract
Age-related osteoarthritis (OA) is a degenerative joint disease characterized by pathological changes in nearly every intra- and peri-articular tissue that contributes to disability in older adults. Studying the etiology of age-related OA in humans is difficult due to an unpredictable onset and insidious nature. A barrier in developing OA modifying therapies is the lack of translational models that replicate human joint anatomy and age-related OA progression. The purpose of this study was to determine whether the common marmoset is a faithful model of human age-related knee OA. Semi-quantitative microCT scoring revealed greater radiographic OA in geriatric versus adult marmosets, and the age-related increase in OA prevalence was similar between marmosets and humans. Quantitative assessments indicate greater medial tibial cortical and trabecular bone thickness and heterogeneity in geriatric versus adult marmosets which is consistent with an age-related increase in focal subchondral bone sclerosis. Additionally, marmosets displayed an age-associated increase in synovitis and calcification of the meniscus and patella. Histological OA pathology in the medial tibial plateau was greater in geriatric versus adult marmosets driven by articular cartilage damage, proteoglycan loss, and altered chondrocyte cellularity. The age-associated increase in medial tibial cartilage OA pathology and meniscal calcification was greater in female versus male geriatric marmosets. Overall, marmosets largely replicate human OA as evident by similar 1) cartilage and skeletal morphology, 2) age-related progression in OA pathology, and 3) sex differences in OA pathology with increasing age. Collectively, these data suggest that the common marmoset is a highly translatable model of the naturally occurring, age-related OA seen in humans.

Pharmacokinetic Study of Conjugated Equine Estrogens in Healthy Chinese Postmenopausal Women Using a Parallel Two-Column LC-MS/MS Method. Clin Pharmacokinet 2022; 61:1571-1583. [PMID: 36173592 DOI: 10.1007/s40262-022-01177-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 08/31/2022] [Indexed: 01/31/2023]
Abstract
BACKGROUND AND OBJECTIVE: Postmenopausal women often require estrogen supplementation to improve menopausal and postmenopausal vasomotor symptoms and maintain hormonal balance. Conjugated equine estrogens extracted from the urine of pregnant mares are commonly used to provide this estrogen replacement therapy. The complex composition of this mixture of animal sulfated metabolites makes its bioanalysis challenging such that its detailed pharmacokinetics has not been fully characterized. The purpose of this work is to reveal the pharmacokinetic behavior of conjugated equine estrogens in healthy Chinese postmenopausal women by a parallel two-column LC-MS/MS method. METHODS An open-label study was carried out in 35 Chinese healthy postmenopausal women who received a single dose of Premarin® 0.625 mg. A high-throughput column-switching liquid chromatography-tandem mass spectrometry method was developed to determine four conjugated estrogens and two unconjugated estrogens formed by hydrolysis in vivo. The method multiplexes two high-performance liquid chromatography systems into one mass spectrometer and incorporates the positive/negative ion switching acquisition mode of mass spectrometry to significantly increase analysis efficiency. Pharmacokinetics was determined using non-compartmental methods. RESULTS Both conjugated and unconjugated estrogens can be analyzed simultaneously in a single run with an analysis time of 13.0 minutes in the column-switching liquid chromatography-tandem mass spectrometry method as opposed to 23.0 minutes in a single-column liquid chromatography-tandem mass spectrometry system. The exposures (maximum concentration and area under the curve) of estrone and equilin in Chinese women were higher than those in the North American women. CONCLUSIONS The fully validated assay was successfully applied to a pharmacokinetic study in healthy postmenopausal Chinese women after oral administration of a conjugated equine estrogen tablet. This study suggests that Chinese postmenopausal women achieve the same level of unconjugated estrogens in plasma at a lower dose of conjugated equine estrogens than North American women.

Aromatase Inhibition Eliminates Sexual Receptivity Without Enhancing Weight Gain in Ovariectomized Marmoset Monkeys. J Endocr Soc 2022; 6:bvac063.

Abstract
Context Ovarian estradiol supports female sexual behavior and metabolic function. While ovariectomy (OVX) in rodents abolishes sexual behavior and enables obesity, OVX in nonhuman primates decreases, but does not abolish, sexual behavior, and inconsistently alters weight gain. Objective We hypothesize that extra-ovarian estradiol provides key support for both functions, and to test this idea, we employed aromatase inhibition to eliminate extra-ovarian estradiol biosynthesis and diet-induced obesity to enhance weight gain. Methods Thirteen adult female marmosets were OVX and received (1) estradiol-containing capsules and daily oral treatments of vehicle (E2; n = 5); empty capsules and daily oral treatments of either (2) vehicle (VEH, 1 mL/kg, n = 4), or (3) letrozole (LET, 1 mg/kg, n = 4). Results After 7 months, we observed robust sexual receptivity in E2, intermediate frequencies in VEH, and virtually none in LET females (P = .04). By contrast, few rejections of male mounts were observed in E2, intermediate frequencies in VEH, and high frequencies in LET females (P = .04). Receptive head turns were consistently observed in E2, but not in VEH and LET females. LET females, alone, exhibited robust aggressive rejection of males. VEH and LET females demonstrated increased % body weight gain (P = .01). Relative estradiol levels in peripheral serum were E2 >>> VEH > LET, while those in hypothalamus ranked E2 = VEH > LET, confirming inhibition of local hypothalamic estradiol synthesis by letrozole. Conclusion Our findings provide the first evidence for extra-ovarian estradiol contributing to female sexual behavior in a nonhuman primate, and prompt speculation that extra-ovarian estradiol, and in particular neuroestrogens, may similarly regulate sexual motivation in other primates, including humans.

Abstract
This study aimed to investigate the effect of estrogen withdrawal on bone
tissue in adult female marmoset monkeys. In a 1-year follow-up study we used
quantitative computer tomography to measure total bone mineral density (BMD)
of the proximal tibia and the second-last lumbar vertebral body (L5/L6)
before and 1, 3, 6, and 12 months after ovariectomy. Body mass did not
significantly change during the 1-year observation period. However, a
significant decline of total BMD after ovariectomy was observed in the
proximal tibia but not in L5/L6. In addition, regression analysis showed a
significant positive relationship between BMD and body mass in both tibia
and L5/L6. The results of our study support the idea that ovariectomized
marmoset monkeys may serve as a model to investigate bone loss related to
decline of estrogen production.
