ANGPTL4 plays a paradoxical role in gastric cancer through the LGALS7 and Hedgehog pathways.

Gastric cancer (GC) is a malignant disease worldwide. Angiopoietin-like protein 4 (ANGPTL4) plays a role in pathophysiological processes, including metabolic reprogramming, angiogenesis, proliferation, and metastasis. Current evidence shows conflicting findings regarding the role of ANGPTL4 in the progression of GC.

Differential lipid signaling from CD4 and CD8 T cells contributes to type 1 diabetes development.

Introduction: We reported that Ca-independent phospholipase Aβ (iPLAβ)-derived lipids (iDLs) contribute to type 1 diabetes (T1D) onset. As CD4 and CD8 T cells are critical in promoting β-cell death, we tested the hypothesis that iDL signaling from these cells participates in T1D development.

Methods: CD4 and CD8 T cells from wild-type non-obese diabetic () and .

CircRNAs as upstream regulators of miRNA//HMGA2 axis in human cancer.

High mobility group protein A2 (HMGA2) is widely recognized as a chromatin-binding protein, whose overexpression is observed in nearly all human cancers. It exerts its oncogenic effects by influencing various cellular processes such as the epithelial-mesenchymal transition, cell differentiation, and DNA damage repair. MicroRNA (miRNA) serves as a pivotal gene expression regulator, concurrently modulating multiple genes implicated in cancer progression, including HMGA2.

Routes and molecular mechanisms of central nervous system involvement in acute myeloid leukemia (Review).

Acute myeloid leukemia (AML) is a predominant form of leukemia. Central nervous system (CNS) involvement complicates its diagnosis due to limited diagnostic tools, as well as its treatment due to inadequate therapeutic methodologies and poor prognosis. Furthermore, its incidence rate is unclear.

The interaction between m6A modification and noncoding RNA in tumor microenvironment on cancer progression.

Cancer development is thought to be closely related to aberrant epigenetic regulation, aberrant expression of specific non-coding RNAs (ncRNAs), and tumor microenvironment (TME). The m6A methylation is one of the most abundant RNA modifications found in eukaryotes, and it can determine the fate of RNA at the post-transcriptional level through a variety of mechanisms, which affects important biological processes in the organism. The m6A methylation modification is involved in RNA processing, regulation of RNA nuclear export or localisation, RNA degradation and RNA translation.

Emerging Roles of ncRNAs Regulating PKM2 in Cancer Progression.

Cancer is one of the main reasons for death, and it threatens human life and health. Both the environment and genes can lead to cancers. It dates back more than a million years; more importantly, tumor cells can not be detected until they grow to a large number.

Potential Links between ANRIL and MiRNAs in Various Cancers.

Non-coding RNAs are mainly divided into two categories, one is small non-coding RNA represented by miRNA, and the other is long non-coding RNA longer than 200 bp. Further studies on non-coding RNAs have revealed that long non-coding RNAs not only have carcinogenic effects, but also have potential links with miRNAs. Antisense non-coding RNA in the INK4 locus (ANRIL/CDKN2B-AS1), one of the five subtypes of long non-coding RNA, has been proved to play a role of oncogene in many cancers, such as gastric cancer, cervical cancer, prostate cancer and non-small cell lung cancer.

LncRNA TUG1 and its Molecular Mechanisms in Human Cancer.

As lncRNAs have increasingly been investigated, they are no longer simply defined as RNAs with no transcription capability. Studies have identified significant associations between the abnormal expression of lncRNAs and human diseases, particularly the mechanisms by which lncRNAs play a part in cancers, which are of considerable attention to researchers. As a result of the complex spatial structure, the mechanisms of interaction of lncRNAs in cancer cells are also complicated and diversified.

Autophagy-related ncRNAs: Regulatory Roles and Potential Therapeutic Effects in Digestive System Neoplasms.

Among all cancers in the world, the incidence rate of digestive system neoplasms accounts for about 25%, while the mortality rate accounts for about 35%. Difficulty in detecting early digestive system cancers and its poor prognosis are the two main reasons for the high mortality rate. Understanding of the basic cellular processes is of significance and autophagy is one of these processes.

Discovery of novel small molecules targeting the USP21/JAK2/STAT3 axis for the treatment of triple-negative breast cancer.

The deficiency in available targeted agents and frequency of chemoresistance are primary challenges in clinical management of triple-negative breast cancer (TNBC). The aberrant expression of USP21 and JAK2 represents a characterized mechanism of TNBC progression and resistance to paclitaxel (PTX). Despite its clear that high expression of USP21-mediated de-ubiquitination leads to increased levels of JAK2 protein, we lack regulator molecules to dissect the mechanisms that the interaction between USP21 and JAK2 contributes to the phenotype and resistance of TNBC.

The Cross-Talk of Non-coding RNAs and Inflammation in Human Cancer.

Despite advanced clinical treatment, the mortality rate of cancer patients is high. Recent studies have linked the development of cancer to inflammation. Many cancers are exacerbated by the emergence of inflammatory responses, and non-coding RNAs play an important role in inflammation.

Potential therapeutic targets of the JAK2/STAT3 signaling pathway in triple-negative breast cancer.

Triple-negative breast cancer (TNBC) poses a significant clinical challenge due to its propensity for metastasis and poor prognosis. TNBC evades the body's immune system recognition and attack through various mechanisms, including the Janus Kinase 2 (JAK2)/signal transducer and activator of transcription 3 (STAT3) signaling pathway. This pathway, characterized by heightened activity in numerous solid tumors, exhibits pronounced activation in specific TNBC subtypes.

Drug resistance in breast cancer is based on the mechanism of exocrine non-coding RNA.

Breast cancer (BC) ranks first among female malignant tumors and involves hormonal changes and genetic as well as environmental risk factors. In recent years, with the improvement of medical treatment, a variety of therapeutic approaches for breast cancer have emerged and have strengthened to accommodate molecular diversity. However, the primary way to improve the effective treatment of breast cancer patients is to overcome treatment resistance.

The Emerging Roles of CircPVT1 in Cancer Progression.

CircRNA is stable due to its ring structure and is abundant in humans, which not only exists in various tissues and biofluids steadily but also plays a significant role in the physiology and pathology of human beings. CircPVT1, an endogenous circRNA, has recently been identified from the PVT1 gene located in the cancer risk region 8q24. CircPVT1 is reported to be highly expressed in many different tumors, where it affects tumor cell proliferation, apoptosis, invasion, and migration.

Small-molecule modulators of tumor immune microenvironment.

In recent years, tumor immunotherapy, aimed at increasing the activity of immune cells and reducing immunosuppressive effects, has attracted wide attention. Among them, immune checkpoint blocking (ICB) is the most commonly explored therapeutic approach. All approved immune checkpoint inhibitors (ICIs) are clinically effective monoclonal antibodies (mAbs).

pH regulators and their inhibitors in tumor microenvironment.

As an important characteristic of tumor, acidic tumor microenvironment (TME) is closely related to immune escape, invasion, migration and drug resistance of tumor. The acidity of the TME mainly comes from the acidic products produced by the high level of tumor metabolism, such as lactic acid and carbon dioxide. pH regulators such as monocarboxylate transporters (MCTs), carbonic anhydrase IX (CA IX), and Na/H exchange 1 (NHE1) expel protons directly or indirectly from the tumor to maintain the pH balance of tumor cells and create an acidic TME.

Recent advances in pyruvate dehydrogenase kinase inhibitors: Structures, inhibitory mechanisms and biological activities.

Metabolism is reprogrammed in a variety of cancer cells to ensure their rapid proliferation. Cancer cells prefer to utilize glycolysis to produce energy as well as to provide large amounts of precursors for their division. In this process, cancer cells inhibit the activity of pyruvate dehydrogenase complex (PDC) by upregulating the expression of pyruvate dehydrogenase kinases (PDKs).

Efficacy of Chemoimmunotherapy Chemotherapy for Gastric Cancer: A Meta-Analysis of Survival Outcomes.

Background: Gastric cancer has been traditionally treated with chemotherapy as the primary mode of treatment. However, recent studies have shown that chemoimmunotherapy is also effective and, in some cases, better than chemotherapy treatment. Current study aimed to find the efficacy of chemoimmunotherapy versus chemotherapy in the treatment of gastric cancer.

The Impact of miR-122 on Cancer.

MiRNAs are confirmed to be a kind of short and eminently conserved noncoding RNAs, which regulate gene expression at the post-transcriptional level via binding to the 3'- untranslated region (3'-UTR) of targeting multiple target messenger RNAs. Recently, growing evidence stresses the point that they play a crucial role in a variety of pathological processes, including human cancers. Dysregulated miRNAs act as oncogenes or tumor suppressor genes in many cancer types.

Emerging role of competing endogenous RNA in lung cancer drug resistance.

Lung cancer remains one of the most common malignant cancers worldwide, and its survival rate is extremely low. Chemotherapy, the mainstay of lung cancer treatment, is not as effective as it could be due to the development of cellular resistance. The molecular mechanisms of drug resistance in lung cancer remain to be elucidated.

Current Perspectives of Immunotherapy for Hepatocellular Carcinoma.

Hepatocellular carcinoma is the sixth most common tumor and the third leading cause of cancer death worldwide. It ranks fourth in the spectrum of malignant tumor incidence and second in the order of death from major malignant tumors in China. Hepatocellular carcinoma is a complex ecosystem containing non-tumor cells (mainly immune-related cells), and its immunotherapy can stimulate the recognition of specific tumor antigens, inhibit the proliferation of cancer cells, and produce over-memory lymphocytes, which can prevent recurrence.
