This study was undertaken to evaluate the effect of ADAM8 on the proliferation and apoptosis of hepatocytes and hepatoma carcinoma cells during hepatocellular carcinoma (HCC) progression. The expression of ADAM8 was significantly increased with good correlation of PCNA expression increasing and cells apoptosis decreasing during the progression of HCC in the liver of mice. Proliferation experiment in vitro showed that recombinant ADAM8 could induce the expression of PCNA in L02 cells, but not in HepG2 cells. Apoptosis experiment in vitro showed that recombinant ADAM8 did not induce or inhibit the expression of apoptosis-related factors Bcl2, Bax, and Caspase3 in L02 cells, but significantly induced the expression of Bcl2, inhibited the expression of Bax and Caspase3 in HepG2 cells. In conclusion, our study suggested that ADAM8 could promote the proliferation of normal hepatocytes and render hepatoma carcinoma cells more resistant to apoptosis to play important roles during the progression of HCC.

Background: Neuroblastoma (NB), the most prevalent solid tumor in children, arises from sympathetic nervous system and accounts for 15% of pediatric cancer mortality. This malignancy exhibits substantial genetic and clinical heterogeneity, thus complicating treatment strategies. Poly(ADP-ribose) polymerase 1 (PARP1), a key enzyme catalyzing polyADP-ribosylation (PARylation), plays critical roles in various cellular processes, and contributes to tumorigenesis and aggressiveness.

Purpose: Pancreatic ductal adenocarcinoma (PDAC) is one of the most lethal cancers and several studies demonstrate that STAT3 has critical roles throughout the course of PDAC pathogenesis.
Methods: TCGA, microarray, and immunohistochemistry data from a PDAC cohort were used for clinical analyses. Panc89 cells with ADAM8 knockout, re-expression of ADAM8 mutants, and Panc1 cells overexpressing ADAM8 were generated.

Multiple myeloma (MM) is a hematological malignancy whose curability is greatly challenged by recurrent patient relapses and therapy resistance. We have previously proposed the high expression of ADAM8, ADAM9 and ADAM15 (A Disintegrin And Metalloproteinase 8/9/15) as adverse prognostic markers in MM. This study focused on the so far scarcely researched role of ADAM8/9/15 in MM using two patient cohorts and seven human MM cell lines (HMCL).

Background: Mechanical spinal cord injury (SCI) is a deteriorative neurological disorder, causing secondary neuroinflammation and neuropathy. ADAM8 is thought to be an extracellular metalloproteinase, which regulates proteolysis and cell adherence, but whether its intracellular region is involved in regulating neuroinflammation in microglia after SCI is unclear.
Methods: Using animal tissue RNA-Seq and clinical blood sample examinations, we found that a specific up-regulation of ADAM8 in microglia was associated with inflammation after SCI.

Objective: Osteoarthritis (OA) is a degenerative joint disease that affects elderly populations worldwide, causing pain and disability. Alteration of the fibroblast-like synoviocytes (FLSs) phenotype leads to an imbalance in the synovial inflammatory microenvironment, which accelerates the progression of OA. Despite this knowledge, the specific molecular mechanisms of the synovium that affect OA are still unclear.
