Professor Dan Huang's research lab specializes in epidemiological and clinical studies focusing on the associations between lifestyle factors, gallbladder and biliary tract diseases, and the risk of hepatobiliary and pancreatic cancers (HBPCs). The lab also investigates familial and genetic risk factors for gastric cancer, particularly in high-risk Asian populations, and explores rare malignancies such as cardiac and central nervous system lymphomas. Using large-scale cohort studies and advanced imaging techniques like PET/CT, the lab emphasizes early detection, risk stratification, and tailored interventions for improved patient outcomes.

Dental pulp stem cells (DPSCs), as one type of mesenchymal stem cells (MSCs), have the capability of self-renewal and multipotency to differentiate into several cell lineages, including osteogenesis, odontoblasts, chondrogenesis, neurogenesis, and adipogenesis. It has found that tumor necrosis factor-α (TNF-α) can promote osteogenic differentiation of human DPSCs in our previous studies. Other experimentation revealed that signal transducer and activator of transcription 3 (STAT3) underwent a ra
Activation of nuclear receptor estrogen receptor α (ERα) exerts cardiovascular protective effects by modulating the expression of ERα target genes. However, the underlying mechanism remains unclear. PARP1 is a ubiquitous multifunctional nuclear enzyme. In this study, we examined the interplay between PARP1 and ERα, and identified PARP1 as an important regulator of ERα-dependent transcription. We showed that PARP1 could directly bind to ERα, and ERα could be poly(ADP-ribosyl)ated by PARP1. Poly(A
PARP-1 inhibits adiponectin and AdipoR1 expression as well as PPAR gamma transactivation through poly(ADP-ribosyl)ation of PPAR gamma in cultured rat cardiac fibroblasts.
The rising prevalence of bone diseases in an aging population underscores the urgent need for innovative and clinically translatable solutions in bone tissue engineering. While significant progress has been made in refining the chemical properties of biomaterials, the structural design of scaffolds-a critical determinant of repair success-remains comparatively underexplored. Structural parameters such as porosity, pore size, and interconnectivity are not only essential for achieving mechanical s
PARP1 is indispensable for TGF-β1 induced Smad3 activation in rat VSMCs. Targeting PARP1 may be a promising therapeutic approach against vascular diseases induced by dysregulation of TGF-β/Smad3 pathway.
The transcription factor Sp1 is implicated in the activation of G0/G1 phase genes. Modulation of Sp1 transcription activities may affect G1-S checkpoint, resulting in changes in cell proliferation. In this study, our results demonstrated that activated poly(ADP-ribose) polymerase 1 (PARP-1) promoted cell proliferation by inhibiting Sp1 signaling pathway. Cell proliferation and cell cycle assays demonstrated that PARP inhibitors or PARP-1 siRNA treatment significantly inhibited proliferation of h
