Background: Gastric cancer (GC) is the most common malignant tumor of the digestive system. Although progress has been reported in terms of treatment, it is still the second leading cause of cancer-related death. Long non-coding RNAs have been shown to play a key role in human cancers in recent investigations.

There is extensive evidence indicating that long non-coding RNAs (lncRNAs) serve as key regulators of oncogenesis and tumor progression in humans. Through prior study has assessed that LIFR-AS1 plays a key role in various kinds of malignant tumors.

Methods: LBX2-AS1 expression levels in CRC were determined from the GEPIA database and CRC tissues to investigate clinical relevance. meRIP-PCR assays investigated the molecular mechanisms underlying the function of m6A in LBX2-AS1.
Background: MicroRNAs (miRNAs) play an important regulatory role in carcinogenesis and cancer progression. MiR-95-3p has been reported to be an oncogene in hepatocellular carcinoma. However, the role of miR-95-3p in colorectal carcinoma (CRC) remains unclear.

A number of previously studies have observed that the levels of miR-365a-3p expression are dysregulated in many cancers, but the specific role of this miRNA in CRC and its association with patient prognosis remains unclear. : The expression of miR-365a-3p in CRC tissues and cell lines was detected by Real-time Quantitative polymerase chain reaction (RT-qPCR), while the relationship between miR-365a-3p expression and clinicopathological characteristics was further analyzed.

However, whether LINC00520 is involved in the malignant characteristics of colorectal cancer (CRC) has not been extensively studied until recently. Therefore, the present study aimed to detect LINC00520 expression in CRC and evaluate its clinical significance in patients with CRC.

In the present study, we report the first known case of a pelvic CFP in China in a 67-year-old male patient. The solitary tumor had an extremely regular shape and was in the vicinity of the sigmoid colon.

The microRNA (miRNA) miR-196-5p has been shown to modulate the progression of several cancer types, but its roles in HCC remain uncertain. In the present report we observed significant miR-196-5p downregulation in HCC tissues and cells, and we found that the expression of this miRNA significantly impaired the proliferation and metastatic potential of HCC in vitro and in vivo.

In the present study, we found NOVA1 to be expressed at higher levels in CRC cell lines and tissue samples, and this upregulation was positively correlated with TNM stage (p = 0.034), poor differentiation (p = 0.

Tropomodulin 3 (TMOD3) is a member of the pointed end capping protein family that contributes to invasion and metastasis in several types of malignancies. It has been found to be crucial for the membranous skeleton and embryonic development, although, its role in HCC progression remains largely unclear.

In this study, we show that miR-212-3p is down-regulated in HCC cell lines and tissues, and correlates with vascular invasion (p = 0.001), and the absence of capsule formation (p = 0.

Aberrant expression of miR-197-3p has been reported in various human malignancies. However, the role of miR-197-3p in the progression and prognosis of hepatocellular carcinoma (HCC) remains unknown.

Methods: A 22-gene panel consisting of 103 hotspot regions was utilized in the formalin-fixed paraffin-embedded (FFPE) tissue samples of 207 CRC patients, using the next-generation sequencing (NGS)-based multiplex PCR technique. Those 22 genes included AKT1, ALK, BRAF, CTNNB1, DDR2, EGFR, ERBB2, ERBB4, FBXW7, FGFR1, FGFR2, FGFR3, KRAS, MAP2K1, MET, NOTCH1, NRAS, PIK3CA, PTEN, SMAD4, STK11, and TP53.
