Purpose: Osteosarcoma (OS) is the most common malignant tumor associated with poor patient outcomes and a limited availability of therapeutic agents. Scutellarein (SCU) is a monomeric flavone bioactive compound with potent anti-cancer activity. However, the effects and mechanisms of SCU on the growth of OS remain unknown.

Our previous study revealed a link between O-GlcNAc transferase (OGT) localization and protein phosphatase 2A (PP2A) activity in osteoblast. Given the association of PP2A downregulation with osteoblast differentiation, we hypothesized that OGT localization changes during this process. We examined OGT localization in MC3T3-E1 cells undergoing differentiation under normal and high glucose conditions.

Osteoporosis is a chronic disease distinguished by decreased bone density and degradation of bone microstructure, frequently linked with inflammation and oxidative stress, both of which contribute to the acceleration of bone resorption. The compound 5,7-Dihydroxy-4-methylcoumarin (D4M) present in Artemisia dracunculus exhibits significant antioxidant and anti-inflammatory properties. Nonetheless, the potential anti-osteoporotic effects of D4M, along with the molecular targets and mechanisms responsible for these effects, have not been studied.

Splanchnic vein thrombosis (SVT), which is particularly prevalent in myeloproliferative neoplasms (MPNs), has a multifactorial pathomechanism involving the anticoagulant protein C (PC) pathway. To better characterize the hypercoagulable state in SVT we assessed its key enzymes thrombin and activated PC (APC). The study population included 73 patients with SVT, thereof 36 MPN+, confirmed by bone marrow biopsy, 37 MPN-, and 30 healthy controls.

Transcription factors play important roles in the growth and development of various tissues in pigs, such as muscle, fat, and bone. A transcription-factor-scale activation library based on the clustered, regularly interspaced, short palindromic repeat (CRISPR)/CRISPR-associated endonuclease Cas9 (Cas9) system could facilitate the discovery and functional characterization of the transcription genes involved in a specific gene network. Here, we have designed and constructed a CRISPR activation (CRISPRa) sgRNA library, containing 5056 sgRNAs targeting the promoter region of 1264 transcription factors in pigs.
