Assays of Ki67, colony formation, Matrigel invasion, and the xenograft animal study were used to assess the cell proliferation, invasion, and tumorigenesis in vitro and in vivo.

Multivariate analysis revealed that low ATF3/GDF15 but not a single low expression of ATF3 is an independent prognostic factor for progression-free survival of bladder cancer patients. Ectopic overexpression of ATF3 downregulated cell proliferation and invasion in bladder cancer cells in vitro, while ATF3-knockdown reversed these results. Knockdown of ATF3 upregulated EMT markers to enhance cell invasion in vitro and downregulated GDF15, NDRG1, and KAI-1 to elevate tumor growth in vivo. The activation of metformin on ATF3 and GDF15 in bladder cancer cells was blocked by SB431542, a TGFβ receptor inhibitor. ATF3 positively regulated GDF15 expression in bladder cancer cells through a feedback loop.</p><p><strong>Conclusions: </strong>Our results identify that ATF3 is a metformin-upregulated antitumor gene.

As well-known, LT for HCC based on the Milan criteria has shown satisfactory outcomes. However, numerous expanded transplantation criteria were proposed to benefit more patients for LT and showed comparable survivals as well. In addition, a modest expansion of transplantation criteria for HCC may be acceptable on the basis of the consensus within the transplantation community. Nonetheless, LT in patients with advanced HCC and portal vein tumor thrombosis (PVTT) recently has received attention and has been reported by many transplantation centers despite being contraindicated. Of those, the LT outcomes in certain HCC patients with PVTT were favorable. Additionally, the advancement of multimodality treatments and the evolution of systemic therapies have emerged as promising therapeutic options for downstaging advanced HCC prior to LT. Somehow, advanced HCC with PVTT could be downstaged to become eligible for LT through these multidisciplinary approaches. Although the available evidence of LT for HCC with PVTT is limited, it is hoped that LT may soon be more widely indicated for these patients.
