Abstract
A 71-year-old woman was diagnosed with a tumor in the pancreatic head on CT imaging, which was performed as a close examination of an exacerbation of diabetes mellitus. The pancreatic tumor was diagnosed as resectable pancreatic cancer, and after preoperative adjuvant chemoradiotherapy, pancreatoduodenectomy was performed as a radical surgery. There were no residual tumor cells in the resected specimen histopathologically, and the patient was judged to have a pathological complete response(pCR). Six months of postoperative adjuvant chemotherapy was administered, but peritoneal recurrence was observed at 20 months postoperatively, and the patient is currently undergoing treatment for recurrence. There have been other reports of recurrence even after pCR was achieved with preoperative treatment, so it is important to follow up carefully, keeping in mind that pancreatic cancer is a latent systemic disease.

Abstract
We previously identified the AKT-phosphorylation sites in nuclear receptors and showed that phosphorylation of S379 in mouse retinoic acid γ and S518 in human estrogen receptor α regulate their activity independently of the ligands. Since this site is conserved at S510 in human liver receptor homolog 1 (hLRH1), we developed a monoclonal antibody (mAb) that recognized the phosphorylation form of hLRH1S510 (hLRH1pS510) and verified its clinicopathological significance in hepatocellular carcinoma (HCC). We generated the anti-hLRH1pS510 mAb and assessed its selectivity. We then evaluated the hLRH1pS510 signals in 157 cases of HCC tissues by immunohistochemistry because LRH1 contributes to the pathogenesis of diverse cancers. The developed mAb specifically recognized hLRH1pS510 and worked for immunohistochemistry of formalin-fixed paraffin-embedded tissues. hLRH1pS510 was exclusively localized in the nucleus of HCC cells, but the signal intensity and positive rates varied among the subjects. According to the semi-quantification, 45 cases (34.9%) showed hLRH1pS510-high, and the remaining 112 cases (65.1%) exhibited hLRH1pS510-low. There were significant differences in the recurrence-free survival (RFS) between the two groups, and the 5-year RFS rates in the hLRH1pS510-high and hLRH1pS510-low groups were 26.5% and 46.1%, respectively. In addition, high hLRH1pS510 was significantly correlated with portal vein invasion, hepatic vein invasion, and high levels of serum alpha-fetoprotein (AFP). Furthermore, multivariable analysis revealed that hLRH1pS510-high was an independent biomarker for HCC recurrence. We conclude that aberrant phosphorylation of hLRH1S510 is a predictor of poor prognosis for HCC. The anti-hLRH1pS510 mAb could provide a powerful tool to validate the relevance of hLRH1pS510 in pathological processes such as tumor development and progression.

Abstract
The ability to engineer biologically viable hepatocytes and tissue matrices with long-term functional maintenance has attracted considerable interest in the fields of hepatocyte transplantation and liver tissue engineering. Here, newly developed hepatocyte sheets supplemented with adipose-derived stem cells (ADSCs) were evaluated to assess the effects of ADSCs on hepatocyte function and engraftment into the subcutaneous space. Eight-week-old male C57BL/6J mice were used as donors and 6-week-old male C.B-17/Icr-scid/scid mice were used as recipients. Hepatocyte-ADSC composite sheets were developed using temperature-responsive culture dishes. Hepatocyte viability in the hepatocyte-ADSC composite sheets was evaluated in an in vitro assay, and the outcome of subcutaneous transplantation of the sheet was evaluated. Hepatocyte viability was sustained in the hepatocyte-ADSC composite sheets in vitro. Albumin secretion was significantly higher (p = 0.015) in the hepatocytes of the hepatocyte-ADSC composite sheets (70.5 μg/mL) than in hepatocyte-only sheets (24.0 μg/mL). Cytokine assays showed that hepatocyte growth factor and interleukin-6 were contributed by ADSCs and not hepatocytes, which were not capable of constitutively secreting them. Immunohistochemically, phosphorylated STAT3 and c-MET expression in hepatocytes in the hepatocyte-ADSC composite sheets was significantly higher than that in the hepatocyte-only sheets. Engraftment of the transplanted hepatocyte-ADSC composite sheets was significantly enhanced without pretreatment of the subcutaneous tissue to induce a vascular network. In the hepatocyte-ADSC composite sheets, the viability of the hepatocytes was significantly maintained as the co-cultured ADSCs provided cytokines, enhancing pivotal cell signaling necessary for hepatocyte activity.

Abstract
BACKGROUND This retrospective study aimed to compare the discriminative performance between magnetic resonance elastography (MRE) and biological markers in detecting liver fibrosis and in predicting postoperative ascites (PA). METHODS We enrolled 77 patients consecutively who underwent hepatectomy between March 2017 and June 2019. Liver fibrosis was histopathologically graded using the METAVIR scoring system as reference. Discriminative performance of non-invasive assessments in detecting different stages of liver fibrosis and predicting PA was evaluated by receiver-operator curve analysis. RESULTS The concordance indices (C-indices) for MRE and biological markers for detecting significant fibrosis (≥F2) and cirrhosis (F4) were: MRE, 0.84 and 0.86; Wisteria floribunda agglutinin + Mac-2 binding protein (WM2BP), 0.63 and 0.71; Hyaluronic acid (HA), 0.72 and 0.75; 7 S-type 4 collagen (T4C), 0.61 and 0.66; APRI, 0.76 and 0.83; and Fib-4, 0.75 and 0.76. Univariable logistic analysis for predicting PA showed that C-indices were 0.751 (p = 0.007), 0.798 (p = 0.106), 0.771 (p = 0.050), 0.674 (p = 0.855), 0.655 (p = 0.263), and 0.560 (p = 0.640) for MRE, WM2BP, Fib-4, HA, APRI, and T4C, respectively. CONCLUSION MRE has a higher diagnostic performance than biological markers in detecting the stages of liver fibrosis and is a predictor for PA after hepatectomy.
