In this study, we used mice with a conditional knockout (cKO) of <i>LRP5</i> in mature osteoblasts, which presented decreased osteogenesis.

This paper first reviewed the effects of macroautophagy and mitophagy on the structure and function of skeletal muscle in COPD, and then explored the mechanism of autophagy mediating the dysfunction of skeletal muscle in COPD. The results showed that macroautophagy- and mitophagy-related proteins were significantly increased in COPD skeletal muscle. Promoting macroautophagy in COPD improves myogenesis and replication capacity of muscle satellite cells, while inhibiting macroautophagy in COPD myotubes increases their diameters.

A total of 260 Ross 308 broilers aged 1‍-‍40 d were divided into the following four groups of 65 birds each: control group, which was fed the main diet (MD), and three experimental groups, which were fed MD supplemented with GLY, GLY+ANTs (enrofloxacin and colistin methanesulfonate), and GLY+AD (ammonium maduramicin), respectively. The results showed that the addition of GLY, GLY+ANTs, and GLY+AD caused significant changes in the expression of several genes of physiological and economic importance. In particular, genes related to inflammation and apoptosis (interleukin 6 (<i>IL6</i>), prostaglandin-endoperoxide synthase 2 (<i>PTGS2</i>), and caspase 6 (<i>CASP6</i>)) were downregulated by up to 99.1%, and those related to antioxidant protection (catalase (<i>CAT</i>), superoxide dismutase 1 (<i>SOD1</i>) and peroxiredoxin 6 (<i>PRDX6</i>)) by up to 98.6%, compared to controls.

In the bone microenvironment, bone tissue cells play a critical role in regulating angiogenesis, including osteoblasts, bone marrow mesenchymal stem cells (BMSCs), and osteoclasts. Osteogenesis and bone angiogenesis are closely linked. The decrease in osteogenesis and bone angiogenesis caused by aging leads to osteoporosis.

In addition, also for the first time, the protective potential of <i>R. aegyptiacum</i> was revealed using an in vivo rat model of UC. The animals were grouped into four categories: normal control (group I), <i>R. aegyptiacum</i> (group II), acetic acid (AA)‍-induced UC (group III), and <i>R. aegyptiacum</i>-treated AA-induced UC (group IV). In group IV, <i>R. aegyptiacum</i> was administered at 0.2 mg/kg daily for one week before and two weeks after the induction of UC. After sacrificing the rats on the last day of the experiment, colon tissues were collected and subjected to histological, immunohistochemical, and biochemical investigations. There was a remarkable improvement in the histological findings of the colon tissues in group IV, as revealed by hematoxylin and eosin (H&E) staining, Masson's trichrome staining, and periodic acid-Schiff (PAS) staining. Normal mucosal surfaces covered with a straight, intact, and thin brush border were revealed. Goblet cells appeared magenta in color, and there was a significant decrease in the distribution of collagen fibers in the mucosa and submucosal connective tissues. All these findings were comparable to the respective characteristics of the control group. Regarding cyclooxygenase-2 (COX-2) immunostaining, a weak immune reaction was shown in most cells. Moreover, the colon tissues were examined using a scanning electron microscope, which confirmed the results of histological assessment. A regular polygonal unit pattern was seen with crypt orifices of different sizes and numerous goblet cells. Furthermore, the levels of catalase (CAT), myeloperoxidase (MPO), nitric oxide (NO), interleukin-6 (IL-6), and interlukin-1β (IL-1β) were determined in the colonic tissues of the different groups using colorimetric assay and enzyme-linked immunosorbent assay (ELISA).
