Objective: Biliary atresia (BA) is a progressive fibro-obliterative disease of the biliary tract, which results in end-stage liver disease. However, liver fibrosis progression may continue even after Kasai surgery. Recent evidence showed that collagen plays a pivotal role in the progression of liver fibrosis in BA. However, most studies were conducted in developed countries. We investigated the expressions of the collagen gene cluster (COL6A1, COL6A2, COL6A3, and COL1A1) in BA patients in Indonesia.
Results: There was a significant down-regulated expression of COL6A1 (ΔC 9.06 ± 2.64 vs. 5.42 ± 2.41; p = 0.0009), COL6A2 (ΔC 8.25 ± 2.07 vs. 5.77 ± 3.51; p = 0.02), COL6A3 (ΔC 11.2 ± 6.08 vs. 6.78 ± 3.51; p = 0.024), and COL1A1 (ΔC 3.26 ± 1.71 vs. 0.19 ± 2.76; p = 0.0015) in BA patients compared to controls. Interestingly, the collagen gene cluster expressions were significantly associated with the presence of cirrhosis (p = 0.0085, 0.04, and 0.0283 for COL6A1, COL6A2, and COL6A3, respectively). In conclusion, our study shows the changes in the collagen gene cluster, particularly collagen type I and VI, expressions in patients with BA in a particular developing country. Our findings suggest the role of these collagen gene clusters in the liver fibrogenesis of BA.

Cells are subjected to dynamic mechanical environments which impart forces and induce cellular responses. In age-related conditions like pulmonary fibrosis, there is both an increase in tissue stiffness and an accumulation of senescent cells. While senescent cells produce a senescence-associated secretory phenotype (SASP), the impact of physical stimuli on both cellular senescence and the SASP is not well understood.

Background: Skeletal fluorosis is a chronic metabolic bone disease caused by excessive accumulation of fluoride in the bones. Previous studies have found that when the intake of tea fluoride is similar, the prevalence of skeletal fluorosis varies greatly among different ethnic groups, which may be related to different genetic backgrounds. Single nucleotide polymorphisms (SNPs) of estrogen receptor 1 (ESR1) and collagen type 1 α1 (COL1A1) were strongly associated with bone metabolism as well as bone growth and development, but their association with the risk of skeletal fluorosis has not been reported.

Lipid nanoparticle (LNP)-mediated RNA delivery holds significant potential for the treatment of various liver diseases. Ionizable lipids play a crucial role in the formulation of LNPs and directly influence their delivery efficiency. In this study, we introduced an innovative concept by incorporating an ether bond into the hydrophobic tail of ionizable lipids for the first time.

The extracellular matrix (ECM) and its primary chemical components, including collagen, play a pivotal role in carcinogenesis and tumor progression. The ECM actively regulates cell proliferation, migration, and, importantly, resistance to various adverse factors. It is widely recognized as a key factor in modifying the resistance of tumor cells to various treatment modalities and cytotoxic compounds.

Fatty acid and retinol binding proteins (FARs) are lipid-binding protein that may be associated with modulating nematode pathogenicity to their hosts. However, the functional mechanism of FARs remains elusive. We attempt to study the function of a certain FAR that may be important in the development of Nippostrongylus brasiliensis.
