A strain of Phoma species improves drought tolerance of Pinus tabulaeformis.

Global warming has led to frequent droughts, posing challenges for afforestation in arid and semiarid regions. In search of labor-saving and money-saving methods to improve the survival and growth rates of trees in these regions, we isolated and identified fungal endophytes that can potentially enhance the drought-resistance abilities of seedlings. We isolated 93 endophytic strains from the roots of Pinus tabulaeformis trees grown on an arid cliff.

Distribution Dynamics and Roles of Starch in Non-photosynthetic Vegetative Organs of Linn., a Hemiparasitic Tree.

Allocation dynamics of stored starch plays essential roles in the development and growth of trees. Previous studies focused on the dynamics and the characteristics of starch in autotrophic trees. However, although starch granules have been detected in the organs or tissues of some parasitic plants, studies on the allocation dynamics and roles of storage starch in them are limited.

Marked thickening of muscularis mucosae and submucosa in the gastric cardia: A histopathological study of 110 surgical resection cases.

Objective: To investigate histopathologic changes of muscularis mucosae (MM) and submucosa in the gastric cardia.

Methods: We performed a histopathology study of 50 distal esophagectomies with proximal gastrectomies for esophageal squamous cell carcinoma as the study (non-cancerous cardiac) group and 60 gastrectomies for early gastric cardiac carcinoma as the cancer group. The gastroesophageal junction was defined as the distal end of squamous epithelium, multilayered epithelium, or deep esophageal glands or ducts.

Emerging evidence supports grouping by location of early gastric carcinoma for appropriate clinical management in Chinese patients.

Gastric cancer is common in China. At present, early detection with prompt resection of early gastric carcinoma (EGC) is crucial for improving patient's survival. Because of high heterogeneity of EGC in Chinese patients we reviewed recent clinicopathological and molecular evidence and proposed a grouping EGC in three subgroups according to their location for appropriate management.

Aim: To investigate the relationship between histological mixed-type of early gastric cancer (EGC) in the mucosa and submucosa and lymph node metastasis (LNM).

Methods: This study included 298 patients who underwent gastrectomy for EGC between 2005 and 2012. Enrolled lesions were divided into groups of pure differentiated (pure D), pure undifferentiated (pure U), and mixed-type according to the proportion of the differentiated and undifferentiated components observed under a microscope.

Risk factors of lymph node metastasis in 1620 early gastric carcinoma radical resections in Jiangsu Province in China: A multicenter clinicopathological study.

Objective: To investigate risk factors of lymph node metastasis (LNM) in early gastric carcinoma (EGC) in four tertiary medical centers in Jiangsu Province, China.

Methods: Among 10 097 consecutive combined gastric cancer radical resections, 1903 EGC were identified and reviewed, 283 excluded and 1620 included in the study. All pathological and some endoscopic reports were reviewed for patients' characteristics, tumor location, gross features, and the number of lymph nodes retrieved and involved.

Hypoxia-inducible factor-1 alpha Correlates with Tumor-Associated Macrophages Infiltration, Influences Survival of Gastric Cancer Patients.

Hypoxia was a common feature for accelerating tumor metastasis by both inducting epithelial-mesenchymal transition (EMT) of tumor cells and polarization of tumor-associated macrophages (TAMs). The association and roles between hypoxia, EMT and TAMs in the biological behavior of gastric cancer (GC) for the time being recurrence is unclear. hypoixa by expression of hypoxia-inducible factor-1 alpha (HIF-1α), polarized functional status of infiltrated TAMs by immunohistochemical staining of CD68 and CD163, and the expression of E-cadherin as EMT property had been evaluated in 236 patients consecutive with histologically confirmed GC.

Regulation of CD44v6 expression in gastric carcinoma by the IL-6/STAT3 signaling pathway and its clinical significance.

As a cancer stem cell marker, CD44 variant 6 (CD44v6) has been implicated in carcinogenesis, tumor progression, and metastasis in a variety of human carcinomas. However, little is known about the expression of CD44v6 in Gastric Carcinoma (GC). Therefore we investigated CD44v6 expression in clinical specimen and further explore the underlying molecular mechanisms.

High Infiltration of Polarized CD163 Tumor-Associated Macrophages Correlates with Aberrant Expressions of CSCs Markers, and Predicts Prognosis in Patients with Recurrent Gastric Cancer.

As the most predominant tumor-infiltrating immune cells, tumor-associated macrophages (TAMs) are associated with poor outcome in multiple solid cancers and play important roles in cancer progression. Cancer stem cells (CSCs) may account for metastasis and recurrence after cancer therapy. However, the association between TAMs and CSCs is not clarified in gastric cancer (GC).

Risk factors of lymph node metastasis in early gastric carcinomas diagnosed by WHO criteria in 379 Chinese patients.

Objective: To investigate risk factors of lymph node metastasis (LNM) in Chinese early gastric carcinoma (EGC) patients diagnosed using the World Health Organization (WHO) criteria and compare the differences in those factors between proximal (PGC) and distal gastric carcinoma (DGC).

Methods: Among 3 176 gastric cancer resections we identified 379 (11.9%) consecutive EGC (104 PGC and 275 DGC) with lymphadenectomy performed at the Affiliated Nanjing Drum Tower Hospital of Nanjing University (Nanjing, Jiangsu Province, China) between January 2005 and December 2012.

Uracil-DNA Glycosylase UNG Promotes Tet-mediated DNA Demethylation.

In mammals, active DNA demethylation involves oxidation of 5-methylcytosine (5mC) into 5-formylcytosine (5fC) and 5-carboxylcytosine (5caC) by Tet dioxygenases and excision of these two oxidized bases by thymine DNA glycosylase (TDG). Although TDG is essential for active demethylation in embryonic stem cells and induced pluripotent stem cells, it is hardly expressed in mouse zygotes and dispensable in pronuclear DNA demethylation. To search for other factors that might contribute to demethylation in mammalian cells, we performed a functional genomics screen based on a methylated luciferase reporter assay.

Risk factors of early proximal gastric carcinoma in Chinese diagnosed using WHO criteria.

Objective: The incidence of proximal gastric carcinoma (PGC) is rising worldwide for unknown reasons. Herein we compare the risk factors of early PGC with distal gastric carcinoma (DGC) in patients treated at a single tertiary hospital in China.

Methods: Risk factors of 379 consecutive surgically resected early gastric carcinoma (EGC) diagnosed according to the 2010 World Health Organization criteria were studied by reviewing their medical records and esophagogastroduodenoscopy/biopsy findings and interviewing patients and family members for the patients' history of environmental toxin exposure (ETE), dietary habits, family (FCH) and personal cancer history (PCH) and survival.

Treatment of gallbladder stone with common bile duct stones in the laparoscopic era.

Background: Laparoscopic common bile duct exploration (LCBDE) for stone can be carried out by either laparoscopic transcystic stone extraction (LTSE) or laparoscopic choledochotomy (LC). It remains unknown as to which approach is optimal for management of gallbladder stone with common bile duct stones (CBDS) in Chinese patients.

Methods: From May 2000 to February 2009, we prospective treated 346 consecutive patients with gallbladder stones and CBDS with laparoscopic cholecystectomy and LCBDE.

Combined epithelial-mesenchymal transition with cancer stem cell-like marker as predictors of recurrence after radical resection for gastric cancer.

Background: The aim of the study was to identify the incidence and the predictors of recurrence after curative resection and the clinical significance of epithelial-mesenchymal transition (EMT) and stem cell-like phenotypes in gastric cancer.

Methods: In a total of 1,463 patients that underwent curative resection for gastric cancer between January 2001 and January 2008 at Drum Tower Hospital, 402 (27.5%) experienced recurrence.

Tet and TDG mediate DNA demethylation essential for mesenchymal-to-epithelial transition in somatic cell reprogramming.

Tet-mediated DNA oxidation is a recently identified mammalian epigenetic modification, and its functional role in cell-fate transitions remains poorly understood. Here, we derive mouse embryonic fibroblasts (MEFs) deleted in all three Tet genes and examine their capacity for reprogramming into induced pluripotent stem cells (iPSCs). We show that Tet-deficient MEFs cannot be reprogrammed because of a block in the mesenchymal-to-epithelial transition (MET) step.

Reevaluating significance of perineural invasion in gastric cancer based on double immunohistochemical staining.

Context: In gastric cancer, the significance of perineural invasion remains controversial. Detecting perineural invasion with hematoxylin-eosin staining often leads to misdiagnosis. Labeling nerves by immunohistochemistry greatly assists perineural invasion detection, but it might also be misdiagnosed, because scattered cancer cells are difficult to recognize.
