These results indicate that a decrease in hepatic cathepsin expression in NAFLD is associated with autophagic dysfunction. Hepatic inflammation correlates with autophagic dysfunction in NAFLD. These findings indicate that the suppression of autophagic proteolysis by hepatic steatosis is involved in the pathogenesis of NAFLD.

We performed post-marketing surveillance to evaluate the safety and efficacy of cell-free and concentrated ascites reinfusion therapy (CART). In total, 356 CART sessions in 147 patients at 22 centers were performed. The most common primary disease was cancer (128 cases, 300 sessions). Mean amount of ascites collected was 3.7 L, and mean concentration ratio was 9.2. Mean amount of reinfused protein was 67.8 g (recovery rate, 72.0%). Performance status, dietary intake, urine volume, body weight and abdominal circumference were significantly improved after CART. Body temperature increased significantly, by 0.3°C on average. Concomitant steroids and/or NSAIDs use before reinfusion was significantly and negatively associated with increases in body temperature. Most adverse events were fever and chills. This study examined a large number of patients compared with previous studies, and showed that CART is an effective and relatively safe treatment for refractory ascites, such as malignant ascites.

Our findings suggest that aberrant CADM1 and 4.1B expression is involved in progression of breast cancer, especially in invasion into the stroma and metastasis.

The prognostic value of BRAF and TERT promoter mutation in papillary thyroid carcinoma (PTC) is controversial. We examined alterations in BRAF and TERT promoter by PCR-direct sequencing in PTC of 144 Japanese patients. Alternative lengthening of telomeres was examined as another mechanism of telomere maintenance by immunohistochemical staining for ATRX and DAXX. Of the clinicopathological characteristics, regional lymph node metastasis, extra-thyroid extension, multifocality/intrathyroidal spread, and advanced stage (III/V) were associated with shorter disease-free survival rate (DFSR). TERT promoter mutation was found in eight patients (6 %), and this was significantly associated with total thyroidectomy, multifocality/intrathyroidal spread, lymph node metastasis and advanced stage. The BRAF mutation was found in 53 patients (38.2 %) but was not associated with any clinicopathological factors. TERT mutations were not correlated with BRAF mutation status. TERT mutation-positive tumors (TERT+) showed lower DFSR than BRAF -mutation-positive tumors (BRAF +), and TERT+/BRAF + tumors showed lower DFSR than BRAF + tumors. No cases showed loss of ATRX/DAXX expression by immunohistochemistry. TERT promoter mutations showed a lower prevalence in our series and appeared to be associated with aggressive behavior. In PTCs, telomerase activation by TERT promoter mutation might be more important than alternative lengthening of telomeres.
