Опубликована: Март 29, 2019

Normal wound healing is a dynamic and complex multiple phase process involving coordinated interactions between growth factors, cytokines, chemokines, various cells. Any failure in these phases may lead wounds to become chronic have abnormal scar formation. Chronic affect patients' quality of life, since they require repetitive treatments incur considerable medical costs. Thus, much effort has been focused on developing novel therapeutic approaches for treatment. Stem-cell-based strategies proposed treat wounds. They shown potential improving the rate regenerating skin. However, there are many challenges using stem cells skin regeneration. In this review, we present some sets data published embryonic cells, induced pluripotent adult Additionally, will discuss different angles whereby can contribute their unique features show current drawbacks.

Updated review of advances in microRNAs and complex diseases: experimental results, databases, webservers and data fusion

Briefings in Bioinformatics, Год журнала: 2022, Номер 23(6)

Опубликована: Сен. 12, 2022

Abstract MicroRNAs (miRNAs) are gene regulators involved in the pathogenesis of complex diseases such as cancers, and thus serve potential diagnostic markers therapeutic targets. The prerequisite for designing effective miRNA therapies is accurate discovery miRNA-disease associations (MDAs), which has attracted substantial research interests during last 15 years, reflected by more than 55 000 related entries available on PubMed. Abundant experimental data gathered from wealth literature could effectively support development computational models predicting novel associations. In 2017, Chen et al. published first-ever comprehensive review MDA prediction, presenting various relevant databases, 20 representative models, suggestions building powerful ones. current review, continuation previous study, we revisit biogenesis, detection techniques functions; summarize recent findings to common miRNA-associated diseases; introduce updates miRNA-relevant databases database releases since present mainstream webservers new webserver 2017 finally elaborate how fusion diverse sources contributed prediction.

Postmenopausal osteoporosis coexisting with sarcopenia: the role and mechanisms of estrogen

Journal of Endocrinology, Год журнала: 2023, Номер 259(1)

Опубликована: Июль 31, 2023

Estrogens (estradiol, estriol, and estrone) are important hormones that directly indirectly regulate the metabolism function of bone skeletal muscle via estrogen receptors. Menopause causes a dramatic reduction in concentration body. This contributes to decline function, thereby resulting osteoporosis sarcopenia. Menopausal women often experience wasting, clinicians recognize as playing an role these conditions, particularly women. Bone closely related endocrine tissues synthesize produce various cytokines. These bone- muscle-derived cytokines, including interleukin-6, irisin, β-aminoisobutyric acid, osteocalcin, fibroblast growth factor-23, sclerostin, both local distant tissues, they mediate crosstalk between muscle. review examines metabolic effects on describes cytokine-mediated bone–muscle conditions deficiency.
