Summary: There is an urgency to find new drugs for high-grade cancers like osteosarcomas, as current therapeutic options are limited. A PORCN inhibitor called ETC-159 has shown promise in clinical trials by inhibiting Wnt, a key driver in these tumors. In vivo and in vitro models demonstrated that ETC-159 reduces beta-catenin staining, increases tumor necrosis, and reduces vascularity, indicating a potential new treatment approach for osteosarcomas.

Summary: In this study, the anti-osteosarcoma (OS) activity of Echinatin (Ecn), a natural active component from licorice, was evaluated and the possible mechanism was explored. It was found that Ecn inhibited the proliferation, migration, and invasion of OS cells, while inducing apoptosis. Ecn also showed synergistic inhibitory effect with cisplatin (DDP) on OS cells. Mechanistically, Ecn inactivated Wnt/β-catenin signaling pathway while activated p38 signaling pathway. These findings provide new insights into the potential therapeutic strategy for OS treatment by combining Ecn with DDP.

Summary: The current design scheme on anti-cancer materials focuses on tuning the mechanical properties of materials and inducing apoptosis in cancer cells through the Rho/ROCK signaling pathway. The study proposes that tuning cell motility could be another important approach to modifying the tumor microenvironment and inducing tumor apoptosis. RGD-modified substrates were used to regulate cell motility, and the effect of motility on tumor cell apoptosis and the involvement of the Wnt signaling pathway were examined. The findings suggest that RGD modification can effectively tune the motility of cancer cells, while high RGD concentration can suppress cell migration and increase the apoptosis rate. The activation of the Wnt-beta-catenin pathway further confirms the critical role of the Wnt pathway in motility-regulated apoptosis of tumor cells.

Summary: This study reveals a positive correlation between FGFR2 expression and osteogenic potential in human adult bone marrow-derived MSCs. Knockdown of FGFR2 leads to downregulation of pro-osteogenic genes and upregulation of pro-adipogenic genes, suppressing osteogenesis. Furthermore, FGFR2 knockdown results in upregulation of EZH2, an enzyme that regulates MSC lineage commitment and suppresses osteogenesis under osteogenic induction.

Summary: This study reveals a long non-coding RNA (MIR181A1HG) that is highly expressed in multipotent mesenchymal stromal cells (MSCs) and down-regulated during osteogenic differentiation. Knockdown of MIR181A1HG impedes cell cycle progression in MSCs and enhances their differentiation into osteo-chondroprogenitors. This study suggests that MIR181A1HG may serve as a regulator of new bone formation in skeletal disorders.

Summary: High-throughput microRNA sequencing was used to study the differentiation of osteoblasts and identify specific microRNAs involved in osteogenesis. The study found that miR-101a is highly upregulated during osteoblast differentiation and plays a role in accelerating mineralization. Transient elevation of miR-101a reduces the levels of Ezh2, a regulatory enzyme, and promotes bone formation. Male mice with overexpression of miR-101a exhibit enhanced trabecular bone parameters, while no significant changes were observed in females. This suggests that the effect of miR-101a on bone formation is influenced by intricate epigenetic mechanisms, which may differ between sexes.

Summary: Vitamin C is crucial for bone health and low levels of serum Vitamin C increase the risk of skeletal fractures. This study examined the effects of Vitamin C on femoral structure, bone formation, and bone mineralization density distribution in mice. The results showed that Vitamin C depletion significantly reduced cortical thickness and bone volume, as well as diminished the amount of newly formed bone tissue. Additionally, Vitamin C supplementation led to higher calcium concentrations and suggested a longer bone tissue age. Female mice were found to be more sensitive to Vitamin C deficiency. These findings highlight the key role of Vitamin C in bone formation rate and its potential in preventing bone-degenerative diseases, especially in females.

Summary: RSC is an essential ATP-dependent chromatin remodeling complex in Saccharomyces cerevisiae. It regulates nucleosome-depleted regions (NDRs) by sliding flanking nucleosomes away from NDRs. Depletion of RSC leads to nucleosome encroachment in NDRs and transcription initiation defects. The study compared the effects of catalytic-dead Sth1 and rapid depletion of Sth1 on transcription. Rapid depletion of Sth1 reduces recruitment of TBP and Pol II, while the catalytic-dead mutant exhibits a severe reduction in TBP binding but accumulates Pol II in coding regions. The results suggest a role for RSC in transcription elongation and termination processes.

Summary: This study analyzed the expression of Ptpn1 and miR-124-3p in testicular tissues of mice and investigated their regulatory relationship. The results showed that Ptpn1 expression was up-regulated in adult mouse testis compared to juvenile mouse testis, while miR-124-3p expression showed an opposite pattern. Further analysis suggested that the down-regulation of miR-124-3p may contribute to the high expression of Ptpn1 in adult mouse testis.
