Abstract Gastric cancer (GC) is a prevalent malignant tumor globally, with high incidence and mortality rates. Advances in understanding molecular mechanisms underlying GC have highlighted the role of microRNAs (miRNAs) in its initiation, progression, and treatment. The Let-7 family, an important class of miRNAs, is closely associated with the biological behaviors of GC. Aberrant expression of various Let-7 family members in GC patients contributes to disease progression, as they target multiple molecular pathways and participate in diverse regulatory mechanisms throughout GC pathogenesis. This article systematically summarizes the expression patterns of Let-7 family members in GC, explores More >

Abstract Carcinogenesis is a multilevel process characterized by genetic and epigenetic alterations, thus contributing to uncontrolled proliferation that eventually leads to cancer. The process of carcinogenesis involves an intricate dis-orchestration in the expression of both, coding and non-coding sequences and is also dependent on the reprogramming of energy metabolism as both direct and indirect consequence of oncogenic mutations. Dysregulated mitochondrial energetics is an important hallmark of cancer, where cancer cells switch to the glycolytic pathway as an alternate source of energy to support the continuous energy supply needed for their indefinite growth. Even though functional mitochondria… More >

Abstract Background: Alterations in splicing factors contribute to aberrant alternative splicing (AS), which subsequently promotes tumor progression. The splicing factor polypyrimidine tract binding protein 1 (PTBP1) has been shown to facilitate cancer progression by modulating oncogenic variants. However, its specific role and underlying mechanisms in hepatocellular carcinoma (HCC) remain to be elucidated. Methods: PTBP1 expression was evaluated in HCC tissues and cell lines. Subsequently, cells were transfected with vectors designed for PTBP1 overexpression or downregulation. The biological function of PTBP1 was assessed in vitro and in vivo using MTS assays, colony formation assays, transwell assays, xenograft formation, tail… More > Graphic Abstract

Abstract Decorin (DCN) is primarily found in the connective tissues of various parts of the body, including the lungs, kidneys, bone tissue, aorta, and tendons. It is an important component of the extracellular matrix (ECM) and belongs to the class I small leucine-rich proteoglycans family. DCN is increasingly attracting attention due to its significant role in tumors, fibrotic diseases, and the regulation of vascular formation. Moreover, its anti-tumor properties have positioned it as a promising biomarker in the fight against cancer. Numerous studies have confirmed that DCN can exert inhibitory effects in various solid tumors, particularly… More >

Abstract Hepatitis B-associated hepatocellular carcinoma (HBV-HCC) remains an intractable high-mortality solid tumor cancer that accounted for 42% of global HCC cases in 2019. Despite some developments in systemic therapy, only a small subset of late-stage HCC patients responds positively to recently developed therapeutic innovations. MicroRNAs (miRNAs) act as an ancillary epigenetic system that can regulate genome expression in all cancer pathways including HCC. The molecular mechanisms of miRNA regulation in cancer pathogenesis offered researchers a new approach that was widely hoped would translate into miRNA-based drugs and diagnostics. Thirty years on, miRNA-based diagnostic and therapeutic agents… More >

Abstract Tazarotene-induced gene 1 (TIG1) is induced by a derivative of vitamin A and is known to regulate many important biological processes and control the development of cancer. TIG1 is widely expressed in various tissues; yet in many cancer tissues, it is not expressed because of the methylation of its promoter. Additionally, the expression of TIG1 in cancer cells inhibits their growth and invasion, suggesting that TIG1 acts as a tumor suppressor gene. However, in some cancers, poor prognosis is associated with TIG1 expression, indicating its protumor growth characteristics, especially in promoting the invasion of inflammatory breast cancer More >

Abstract Introduction: Hepatocellular carcinoma (HCC), a prevalent malignancy, poses significant challenges with high tumor heterogeneity and poor prognosis. MicroRNAs (miRNAs) play a pivotal role in hepatocarcinogenesis. Although abnormalities in microRNA-557 (miR-557) expression have been implicated in various cancer types, its role in HCC remains unclear. Therefore, there is a need to explore the function of microRNA-557 in HCC. Methods: Candidate miRNAs were identified through screening in GSE108724 and GSE20077. Real-time PCR was employed to analyze the expression level of miR-557 in hepatoma cell lines and tissues. Cell viability and migration assays were applied to assess the… More > Graphic Abstract

Abstract Solar ultraviolet B (UVB) radiation is a major skin cancer-causing agent. Initiation, promotion, and progression are the diverse phases of UVB-induced carcinogenesis. Exposure to UVB causes abnormalities in a series of biochemical and molecular pathways: thymine dimer formation, DNA damage, oxidative stress, inflammatory responses, and altered cell signaling, eventually resulting in tumor formation. The increased skin cancer rates urge researchers to develop more efficient drugs, but synthetic chemotherapeutic drugs have more contrary effects and drug resistance issues, which have been reported recently. The current review focuses on the relationship between microbes and cancer. Human skin… More > Graphic Abstract

Abstract Objective: This research was designed to observe the value of miR-1271 and GPC3 in evaluating the prognosis of liver cancer (LC) patients after liver transarterial chemoembolization (TACE). Methods: A total of 80 patients diagnosed as LC in our hospital from January 2018 to April 2019 were included in the LC group (LCG), and then assigned into a survival group (SG) and a death group (DG) based on prognosis. Seventy healthy subjects undergoing physical examination simultaneously were included in the normal group (NG). miR-1271 and GPC3 in serum of two groups of subjects were tested via qRT-PCR.… More >

Abstract MicroRNAs (miRNAs) are small single-stranded, non-coding RNA molecules involved in the pathogenesis and progression of cancer, including osteosarcoma. We aimed to clarify the pathways involving miRNAs using new bioinformatics tools. We applied WikiPathways and PathVisio, two open-source platforms, to analyze miRNAs in osteosarcoma using miRTar and ONCO.IO as integration tools. We found 1298 records of osteosarcoma papers associated with the word “miRNA”. In osteosarcoma patients with good response to chemotherapy, miR-92a, miR- 99b, miR-193a-5p, and miR-422a expression is increased, while miR-132 is decreased. All identified miRNAs seem to be centered on the TP53 network. This is the More >
