Effects of astragalus injection on different stages of early hepatocarcinogenesis in a two-stage hepatocarcinogenesis model using rats. J Toxicol Pathol 2019; 32:155-164. [PMID: 31402807 PMCID: PMC6682553 DOI: 10.1293/tox.2019-0006] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2019] [Accepted: 03/12/2019] [Indexed: 12/18/2022] Open
Abstract
To clarify the suppressive effects of astragalus injection (AI) on different stages of
early hepatocarcinogenesis induced by weak promotion, SD rats initiated with a single
intraperitoneal (i.p.) injection of N-diethylnitrosamine (DEN) at 200
mg/kg body weight and promoted with 0.5% piperonyl butoxide (PBO) in diet were repeatedly
administered AI at 5 ml/kg body weight/day in the early postinitiation (EPI) or late
postinitiation (LPI) period for 2 or 8 weeks, respectively. The number and area of
glutathione S-transferase placental form (GST-P)-immunoreactive
(+) foci tended to increase in the DEN+PBO group compared with the DEN-alone
group. Among the PBO-promoted groups, number and area of GST-P+ foci did not
visibly change in the DEN+PBO+AI-EPI group compared with the DEN+PBO group. In contrast,
number and area of GST-P+ foci tended to decrease in the DEN+PBO+AI-LPI group
compared with the DEN+PBO group. Number of Ki67+ cells was increased in the
DEN+PBO group compared with the DEN-alone group and was decreased in both AI-administered
groups compared with the DEN+PBO group. Gene expression analysis revealed that the
DEN+PBO+AI-LPI group showed increased transcript levels of Ccne1,
Cdkn1b, Rb1, Bax,
Bcl2, Casp3, and Casp9 compared with
the DEN+PBO group; however, the DEN+PBO+AI-EPI group did not show changes in the
transcript levels of any genes examined compared with the DEN+PBO. These results suggest
that AI administration during the LPI period caused weak suppression of
hepatocarcinogenesis under weak promotion with a low PBO dose by the mechanism involving
facilitation of cell cycle suppression causing G1/S arrest and apoptosis via the
mitochondrial pathway. In addition, the results suggest that AI administration during the
EPI period has no effect on weakly promoted hepatocarcinogenesis.

Abstract
BACKGROUND AND AIM The use of BioEnterics intragastric balloon (BIB) is progressively increasing, owing to the fact that morbid obesity becomes a global epidemic together with risks of bariatric surgery. Yet, the possible local BIB effect on gastric mucosa is not clearly elucidated. The aim of the current study was to assess the histological changes occurring in the gastric mucosa post-BIB insertion. METHODS Gastric mucosa biopsy was obtained from 87 cases of morbid obesity both pre-BIB and 6 months post-BIB insertion to compare the local changes by histological and immunohistochemical analysis. RESULTS An inflammatory reaction was detected in the post-BIB mucosa which displayed a positive CD20, CD3 (p < 0.05), and the proliferation index (Ki67) increased significantly compared with that of the pre-BIB cases. The Ki67 index showed a significant positive correlation with CD20 and CD3 immunoexpression in the post-BIB gastric mucosae. CONCLUSION Our results demonstrated a possible increase in the gastric proliferative activity after BIB insertion accompanied with a remarkable local inflammatory reaction. Although these findings may be reactive and transient, endoscopic follow-up is recommended for early detection of further pathological changes.

Abstract
BACKGROUND RING box protein-1 (RBX1) is an essential component of the E3 ubiquitin ligase Skp1/Cullin/RBX1/F-box protein complex. Although an altered expression of RBX1 has been reported in several human cancers, the role of RBX1 in gastric cancer remains unknown. METHODS We investigated the RBX1 expression in primary gastric cancer tissues from 145 patients by immunohistochemistry, and explored its clinical relevance and prognostic value. Furthermore, the effect of RBX1 expression on cancer cell proliferation was analyzed in vitro using a siRNA silencing technique. RESULTS The RBX1 expression was abundant in gastric cancer tissues. There was a significant difference in the expression level of RBX1 in terms of the tumor depth (P = 0.008), presence of distant metastasis (P = 0.016) and venous invasion (P = 0.005). The postoperative overall (P < 0.001) and relapse-free survival (P < 0.001) rates were significantly poorer in patients with RBX1-high tumors than in patients with RBX1-low tumors. There was a significant correlation of the RBX1 status with postoperative hematogenous recurrence (P = 0.013). Importantly, the RBX1 status was identified as an independent prognostic factor for gastric cancer (P = 0.002). Furthermore, RBX1 gene silencing significantly inhibited the proliferation of gastric cancer cells in vitro. CONCLUSIONS The RBX1 expression has a significant prognostic value in gastric cancer. RBX1 might play an important role in regulating the proliferation of gastric cancer cells and promoting the development of postoperative recurrence. Our data provide a rationale for developing a novel therapy targeting RBX1 for gastric cancer.

Abstract
Mina53 is a direct novel target protein of Myc. The present study investigated the expression of mina53 and c-myc in gastric carcinoma and the relationship between Mina53 expression and clinicopathological features. The expression levels of mina53 and c-myc mRNA and protein in gastric cancers and the adjacent normal tissues from 12 patients were assessed by laser-capture microdissection (LCM) combined with quantitative polymerase chain reaction (qPCR) and western blotting, respectively. Immunohistochemical analysis was used to evaluate the expression of the Mina53 protein in normal gastric tissues (n=30), chronic atrophic gastritis without intestinal metaplasia (n=44), intestinal metaplasia (n=34), gastric dysplasia (n=36), intestinal-type gastric carcinoma (IGC) (n=30) and diffuse-type gastric carcinoma (DGC) (n=34). The correlation between expression of mina53 and patient survival time was also investigated. The expression levels of mina53 and c-myc mRNA in the gastric carcinomas were found to be higher when compared to these levels in the adjacent normal tissues. In addition, the expression levels of Mina53 and c-Myc protein in gastric carcinomas were higher when compared with levels in the adjacent normal epithelium. mina53 expression was significantly increased during gastric carcinogenesis and was correlated with different clinicopathological factors in IGC and DGC. The prognosis of patients with low expression of Mina53 was more favorable when compared to the prognosis of patients with high expression of Mina53. mina53 expression was gradually elevated during gastric carcinogenesis, and the overexpression of mina53 was correlated with different clinicopathological features between DGC and IGC cases. Furthermore, the prognosis of gastric carcinoma patients was significantly correlated with the expression of Mina53.

Abstract
Background Gastric cancer is a leading causes of cancer-related deaths ,but the underlying molecular mechanisms of its progression are largely unknown. Differentiated embryonic chondrocyte-expressed gene 1 (DEC1), is an important transcription factor involved in the progression of tumors and has recently been identified to be strongly inducible by hypoxia. Little is known about the contribution of DEC1 to the intracellular hypoxia and proliferation signaling events in gastric cancer. Methods Immunohistochemistry was used to detect the expression of DEC1, hypoxia-inducible factor 1(HIF-1α) and Ki67 in 173 human gastric cancer samples and adjacent non-tumor tissues samples. The relationship between DEC1, HIF-1α and Ki67 was evaluated. Results DEC1 protein was persistently expressed in the nucleus and cytoplasm of gastric cancer tissue. The protein expression of DEC1 and HIF-1α in tumour tissues was 83.8% and 54.3%, respectively, and was significantly higher than that in adjacent normal tissues (83.8% vs 23.7%, P <0.001; 54.3% vs 12.7%, P< 0.001). The expression of DEC1 and HIF-1α was associated with poor histological differentiation. (P < 0. 01). Furthermore, DEC1 level was positively correlated with HIF-1α (P < 0. 01, r=0.290) and Ki67 expression (P < 0. 01, r=0.249). Conclusion The upregulation of DEC1 may play an important role in hypoxia regulation and cell proliferation in gastric cancer. The relevant molecular mechanism requires further investigation.

Abstract
BACKGROUND Patients not fulfilling minimal criteria for myelodysplastic syndromes (MDS) but presenting with persisting cytopenia(s) not attributable to a haematological or non-haematological disease are defined as 'idiopathic cytopenia of undetermined significance' (ICUS). DESIGN AND METHODS We retrospectively analysed 67 of 3504 patients from our MDS Registry fulfilling the criteria for ICUS. Furthermore, we used the human androgen receptor gene-based assay (HUMARA) to look for clonality. RESULTS Of all 67 patients, 66% had unilineage, 18% bilineage and 12% trilineage cytopenias. The majority of patients (67%) presented with anaemia. Median overall survival was 44 months (range: 1-199 months). In the entire group, eight patients (12%) developed acute myeloid leukaemia (AML). Of the 23 patients eligible for HUMARA, 17 had non-clonal X-chromosome inactivation patterns, while 6 patients showed clonal patterns. Two of these six patients developed AML indicating that a clonal stem cell disorder was the reason for the anteceding cytopenia, while there was no AML observed among the 17 patients with non-clonal patterns (P = 0.013). CONCLUSIONS Since some of the ICUS patients had a clonal bone marrow disease when presenting with cytopenia(s) and 8 of 67 patients with ICUS later developed AML, we recommend to follow these patients thoroughly. As demonstrated here, HUMARA can facilitate the discrimination between ICUS and a 'manifest' MDS.
