Procollagen mRNA was isolated from mouse embryos and used for the synthesis of a highly labelled cDNA probe complementary to collagen mRNA. This probe was used for the investigation of procollagen mRNA metabolism during the cell cycle of 3T6 mouse embryo fibroblasts in culture. Titration hybridization experiments revealed that procollagen mRNA was present throughout the cell cycle following stumulation of confluent monolayers. Procollagen mRNA levels of sparse cultures appeared similar to those of unstimulated monolayers. The fluctuating levels of collagen synthesis during the cell cycle can be ascribed to changes in the amount of collagen mRNA present. In mouse sarcoma virus transformed 3T3 cells only 20--30% of the amount of procollagen mRNA in 3T3 cells is present indicating that the decline in collagen synthesis is due to mRNA availability.

Type 2 diabetes and weight loss are associated with detrimental skeletal health. Incretin-based therapies (GLP-1 receptor agonists, and dual GIP/GLP-1 receptor agonists) are used clinically to treat diabetes and obesity. The potential effects of semaglutide and tirzepatide on bone metabolism in type 2 diabetic mice remain uncertain.

Purpose: Procollagen C-proteinase enhancer 1 (PCPE-1) is associated with liver fibrosis, a major risk factor of hepatocellular carcinoma (HCC). However, its role in HCC remains unclear.
Materials And Methods: The mRNA and protein expression levels of PCPE-1 were analyzed using publicly available datasets of HCC tissues and matched normal tissues.

Objective: To investigate the changes in serum homeobox A9 ( ), soluble E-cadherin (SE-CAD) and type Ⅲ procollagen (PCⅢ) levels in acute myeloid leukemia (AML) patients after chemotherapy with DCAG regimen and their relationship with prognosis.
Methods: The clinical data of 80 patients with relapsed/refractory AML diagnosed and treated in our hospital from March 2018 to December 2021 were retrospectively analyzed. According to different treatment regimen, the patients were divided into DCAG group (=40) and CAG group (=40).

Bruck syndrome is an autosomal recessive form of osteogenesis imperfecta caused by biallelic variants in PLOD2 or FKBP10 and is characterized by joint contractures, bone fragility, short stature, and scoliosis. PLOD2 encodes LH2, which hydroxylates type I collagen telopeptide lysines, a critical step for collagen crosslinking. The Plod2 global knockout mouse model is limited by early embryonic lethality, and thus, the role of PLOD2 in skeletogenesis is not well understood.
