Article Abstract
Osteoporosis, which is caused by an imbalance in osteoblasts and osteoclasts, is a global age-related metabolic disease. Osteoblasts induce osteocyte and bone matrix formation, while osteoclasts play an important role in bone resorption. Maintaining a balance between osteoblast formation and osteoclastic absorption is crucial for bone remodeling. Circular RNAs (circRNAs), which are characterized by closed-loop structures, are a class of novel endogenous transcripts with limited protein-coding abilities. Accumulating evidence indicates that circRNAs play important roles in various bone diseases, such as osteosarcoma, osteoarthritis, osteonecrosis, and osteoporosis. Recent studies have shown that circRNAs regulate osteoblast and osteoclast differentiation and may be potential biomarkers for osteoporosis. In the current review, we summarize the expression, function, and working mechanisms of circRNAs involved in osteoblasts, osteoclast differentiation, and osteoporosis.

In recent years, there has been a rapid increase in the incidence of thyroid carcinoma (TC). Our study focuses on the regulatory effect of circular RNAs on metabolism of TC, aiming to provide new insights into the mechanisms of progression and a potential therapeutic target for TC. In this study, we identified high expression levels of circPSD3 in TC tissues through RNA sequencing.

Circular RNA (circRNA) has been confirmed to be a regulator for septic acute kidney injury (AKI). It is reported that circ_0049271 has abnormal expression in AKI patients, but its role and mechanism in septic AKI remain unclear. Lipopolysaccharide (LPS)-stimulated HK-2 cells were served as the cellular model of sepsis-associated AKI (SAKI).

Colorectal cancer (CRC) constitutes a significant global health challenge, accounting for a considerable proportion of cancer cases and associated mortality. Projections indicate a potential increase in new cases by 2040, attributed to demographic factors such as aging and population growth. Although advancements in the understanding of CRC pathophysiology have broadened treatment options, challenges such as drug resistance and adverse effects persist, highlighting the necessity for enhanced diagnostic methodologies.

Backgrounds: Head and neck cancer is among the top ten cancers worldwide, with most lesions in the oral cavity. Oral squamous cell carcinoma accounts for more than 90% of all oral malignancies and is a significant public health concern. Circular RNA and micro RNA, as non-coding RNA, plays an important role in the development of tumor transmission.
