Context: The role of growth differentiation factor 9 (GDF9) and bone morphogenetic protein 15 (BMP15) on aromatase regulation is poorly understood in humans.

Objective: Determine GDF9 and BMP15 effects on follicle-stimulating hormone (FSH) stimulation of estradiol production in primary human cumulus granulosa cells (GCs). We hypothesized that the combination of GDF9 and BMP15 potentiates FSH-induced aromatase expression. Read More

Background/aims: Periosteal tissue is a valuable source of multipotent stem cells for bone tissue engineering. To characterize these cells in detail, we generated an immortalized human cranial periosteal cell line and observed an increased MSCA-1 and CD146 expression, as well as an earlier and stronger mineralization compared to the parental cells. Further, we detected a higher osteogenic potential of MSCA-1high compared to MSCA-1low cranial periosteal cell (CPC) fractions. Read More

Inflammation-induced disappearance of tissue-resident macrophages represents a key pathogen defense mechanism. Using a model of systemic blood-stage malaria, we studied the dynamics of tissue-resident macrophages in multiple organs to determine how they are depleted and refilled during the course of disease. We show that Plasmodium infection results in a transient loss of embryonically established resident macrophages prior to the parasitemia peak. Read More

Leukemic stem cells (LSCs) are thought to be the major cause of the recurrence of acute myeloid leukemia (AML) due to their potential for self-renewal. To identify therapeutic strategies targeting LSCs, while sparing healthy hematopoietic stem cells (HSCs), we performed gene expression profiling of LSCs, HSCs, and leukemic progenitors all residing within the same AML bone marrow and identified insulin-like growth factor-binding protein 7 (IGFBP7) as differentially expressed. Low IGFBP7 is a feature of LSCs and is associated with reduced chemotherapy sensitivity. Read More

Bone metastasis causes bone pain and pathological bone fracture in breast cancer patients with a serious complication. Previous studies have demonstrated that a novel phosphatidyl inositol 3-kinase (PI3K)-mTOR inhibitor PKI-402 suppressed the growth of breast cancer cells. However, the role of PKI-402 involved in osteolysis induced by breast cancer remains unclear. Read More

Telomeres are repetitive nucleotide sequences that cap linear chromosomes, thereby limiting progressive chromosomal shortening during cell replication. In conjunction with environmental factors, common single nucleotide polymorphisms and rare and ultra-rare telomere-related mutations are associated with accelerated telomere shortening resulting in organ dysfunction, including interstitial lung disease (ILD). The most common telomere-related mutation-associated ILD is idiopathic pulmonary fibrosis (IPF). Read More

The signaling pathways of growth factors including platelet-derived growth factor (PDGF) can be considered specific targets for overcoming the poor prognosis of idiopathic pulmonary fibrosis (IPF). Nintedanib, the recently approved multiple kinase inhibitor, has shown promising anti-fibrotic effects in IPF patients; however, its efficacy is still limited, and in some cases, treatment discontinuation is necessary due to toxicities such as gastrointestinal disorders. Therefore, more effective agents with less toxicity are still needed. Read More

For anatomical restoration of a repaired rotator cuff, mechanical augmentation of the repaired structure is essential. Using histological and biomechanical evaluation in a rat model, the authors sought to determine the efficacy of an absorbable alginate sheet at the supraspinatus tendon-to-bone repair site for healing of the rotator cuff tear. Forty adult (12 weeks old) male Sprague- Dawley wild-type rats were used in this study. Read More

Genetic manipulation of NOD/SCID (NS) mice has yielded numerous sub-strains with specific traits useful for the study of human hematopoietic xenografts, each with unique characteristics. Here, we have compared the engraftment and output of umbilical cord blood (UCB) CD34+ cells in four immune-deficient strains: NS, NS with additional IL2RG knockout (NSG), NS with transgenic expression of human myeloid promoting cytokines SCF, GM-CSF, and IL-3 (NSS), and NS with both IL2RG knockout and transgenic cytokine expression (NSGS). Overall engraftment of human hematopoietic cells was highest in the IL2RG knockout strains (NSG and NSGS), while myeloid cell output was notably enhanced in the two strains with transgenic cytokine expression (NSS and NSGS).

Fractures of the femoral neck can occur in young healthy individuals due to high loads occurring during motor vehicle accidents, impacts, or falls. Failure forces are lower if impacts occur sideways onto the greater trochanter as compared with vertical loading of the hip. Bone density, bone geometry, and thickness of cortical bone at the femoral neck contribute to its mechanical strength. Read More

Case: Isolated patella absentia is an extremely rare phenomenon, with only a few published cases and even fewer follow-up reports. Nearly 40 years after the initial presentation of 2 brothers with bilateral congenital absence of the patella and the publication of a case report, we report the clinical and radiographic findings of their subsequent tibiofemoral osteoarthritis, which was treated with bilateral total knee arthroplasty.

Conclusion: Understanding the biomechanical complications associated with congenital absence of the patella as it relates to a stable knee is vital; in the case of degenerative changes, total knee arthroplasty appears to provide a long-term solution for these patients. Read More

Evaluating the nature of chemical bonding for actinide elements represents one of the most important and long-standing problems in actinide science. We directly address this challenge and contribute a Cl K-edge X-ray absorption spectroscopy and relativistic density functional theory study that quantitatively evaluates An-Cl covalency in AnCl (An = Th, U, Np, Pu). The results showed significant mixing between Cl 3p- and An 5f- and 6d-orbitals (t*/t* and t*/e *), with the 6d-orbitals showing more pronounced covalent bonding than the 5f-orbitals. Read More

Activins are dimeric glycoproteins belonging to the transforming growth factor beta superfamily and resulting from the assembly of two beta subunits, which may also be combined with alpha subunits to form inhibins. Activins were discovered in 1986 following the isolation of inhibins from porcine follicular fluid, and were characterized as ovarian hormones that stimulate follicle stimulating hormone (FSH) release by the pituitary gland. In particular, activin A was shown to be the isoform of greater physiological importance in humans. Read More

Calcitonin was discovered over 50 yr ago as a new hormone that rapidly lowers circulating calcium levels. This effect is caused by the inhibition of calcium efflux from bone, as calcitonin is a potent inhibitor of bone resorption. Calcitonin has been in clinical use for conditions of accelerated bone turnover, including Paget's disease and osteoporosis; although in recent years, with the development of drugs that are more potent inhibitors of bone resorption, its use has declined.

Osteoarthritis is the most prevalent form of aging-related joint diseases, and its etiology is still not fully understood. Obesity has been recognized as one of the most significant and potentially preventable risk factors for osteoarthritis. Beyond mechanical loading, adipokines, including leptin, visfatin, adiponectin, resistin and others, are demonstrated to have metabolic implications in the pathogenesis and progression in obesity-induced osteoarthritis by modulating the pro/anti-inflammatory and anabolic/catabolic balance, apoptosis, matrix remodeling and subchondral bone ossification.
