Long noncoding RNA (lncRNA) papillary thyroid carcinoma susceptibility candidate 3 (PTCSC3) inhibits several types of cancer, whereas its role in gastric cancer is unknown. From May 2010 to May 2015, this study included 68 (36 males and 32 females, 35-69 years, 48.3 ± 7.1 years) gastric cancer patients and 60 healthy volunteers (32 males and 28 females, 34-67 years, 48.8 ± 6.5 years). Transient transfections, QPCR, CCK-8, transwell cell migration, and invasion assay were used for carrying out the research. The authors found that plasma PTCSC3 was downregulated in gastric cancer patients. Downregulation of PTCSC3 distinguished early stage gastric cancer patients from healthy controls. LncRNA PTCSC3 expression levels were increased on the day of discharge in gastric cancer patients compared with pretreatment levels. During follow-up, patients with low plasma levels of PTCSC3 showed a significantly lower overall survival rate. PTCSC3 negatively regulated proliferation, invasion, and migration of gastric cancer cells. Therefore, lncRNA PTCSC3 may serve as a biomarker for the treatment and prognosis of gastric cancer.

Long noncoding RNA (lncRNA) PTCSC3 (hereafter PTCSC3 is used to represent lncRNA PTCSC3) inhibits glioma and thyroid cancer, indicating its potential tumor suppression function in other types of cance...
Dysregulation of long non-coding RNA Papillary thyroid carcinoma susceptibility candidate 3 (lncRNA PTCSC3) has been found to correlate with various types of cancers. Quantitative RT-PCR showed a down...
It is known that lncRNA PTCSC3 inhibits thyroid cancer and glioma and STAT3 promotes cancer development. We in this study investigated the potential involvement of PTCSC3 in laryngeal squamous cell ca...
Long non-coding RNA (lncRNA) is closely related to the occurrence and development of gastric cancer, but the mechanism and clinical significance of lncRNA AOC4P are still unclear. This study aimed to ...
The mechanism of gastric cancer is highly complex, accompanied by a variety of genetic abnormalities. It is of great significance to elucidate the pathogenesis of gastric cancer, find its markers and ...
This study aims to analyze the expression of micro-RNA (miRNA) and long non-coding RNA (lncRNA) by next-generation sequencing in patients with high grade serous ovarian cancer (HGSOC) and ...
No accurate, inexpensive and non-invasive test for gastric cancer screening is currently available. The investigators' recent study identified a1-antitrypsin and other proteins as potentia...
In-depth understanding of molecular characteristics of gastric cancer enabled us to realize personalized medicine with targeted agents in gastric cancer treatment. We initiated open-label,...
The purpose of this study is to evaluate sensitivity and specificity of newly defined tumor biomarker with gastric cancer pts and cancer-free healthy volunteers.
Liquid biopsy has been widely used in the diagnosis and treatment of tumors, and cfDNA has always been a hot spot in clinical research. Previous studies have shown that cfDNA may be associ...
A deoxycytidine derivative and fluorouracil PRODRUG that is used as an ANTINEOPLASTIC ANTIMETABOLITE in the treatment of COLON CANCER; BREAST CANCER and GASTRIC CANCER.
That portion of the stomach remaining after gastric surgery, usually gastrectomy or gastroenterostomy for cancer of the stomach or peptic ulcer. It is a common site of cancer referred to as stump cancer or carcinoma of the gastric stump.
A proto-oncogene protein and member of the Wnt family of proteins. It is frequently up-regulated in human GASTRIC CANCER and is a tumor marker (TUMOR MARKERS, BIOLOGICAL) of gastric and COLORECTAL CANCER.
An internationally recognized set of published rules used for evaluation of cancer treatment that define when tumors found in cancer patients improve, worsen, or remain stable during treatment. These criteria are based specifically on the response of the tumor(s) to treatment, and not on the overall health status of the patient resulting from treatment.
Abnormal distention of the STOMACH due to accumulation of gastric contents that may reach 10 to 15 liters. Gastric dilatation may be the result of GASTRIC OUTLET OBSTRUCTION; ILEUS; GASTROPARESIS; or denervation.
The thyroid is a butterfly-shaped gland in the neck, just above thecollarbone and is an endocrine gland that make hormones. These Thyroid hormones control the rate of many activities in the body, including how fast the body burns calories and how fast th...
Cancer is not just one disease but many diseases. There are more than 100 different types of cancer. Most cancers are named for the organ or type of cell in which they start - for example, cancer that begins in the colon is called colon cancer; cancer th...
