Heteronemin suppresses EGF‑induced proliferation through the PI3K/PD‑L1 signaling pathways in cholangiocarcinoma.

Epidermal growth factor (EGF) binds with its surface receptor to stimulate gene expression and cancer cell proliferation. EGF stimulates cancer cell growth via phosphoinositide 3‑kinase (PI3K) and programmed cell death ligand 1 (PD‑L1) pathways. As an integrin αvβ3 antagonist, heteronemin exhibits potent cytotoxic effects against cancer cells.

Histamine N-methyltransferase (HNMT) as a potential auxiliary biomarker for predicting adaptability to anti-HER2 drug treatment in breast cancer patients.

Background: Up to 23% of breast cancer patients recurred within a decade after trastuzumab treatment. Conversely, one trial found that patients with low HER2 expression and metastatic breast cancer had a positive response to trastuzumab-deruxtecan (T-Dxd). This indicates that relying solely on HER2 as a single diagnostic marker to predict the efficacy of anti-HER2 drugs is insufficient.

The Effect of Oncology Nurse Navigation on Mental Health in Patients with Cancer in Taiwan: A Randomized Controlled Clinical Trial.

In this study, we investigated the prevalence of mental health problems among patients with cancer and whether oncology nurse navigation improved their mental health outcomes and medical experience. In this randomized controlled clinical trial, we recruited 128 outpatients with cancer via purposive sampling from a teaching hospital in northern Taiwan. Participants were randomly assigned to the navigation group ( = 61) or the usual care group ( = 67).

2,3,5,4'-Tetrahydroxystilbene-2--β-D-Glucoside improves female ovarian aging.

Reduced fertility associated with normal aging may reflect the over-maturity of oocytes. It is increasingly important to reduce aging-induced infertility since recent trends show people marrying at later ages. 2,3,5,4'-Tetrahydroxystilbene-2--β-D-glucoside (THSG), a polyphenol extracted from , has been reported to have anti-inflammatory and anti-aging properties.

Heteronemin and Tetrac Induce Anti-Proliferation by Blocking EGFR-Mediated Signaling in Colorectal Cancer Cells.

Overexpressed EGFR and mutant play vital roles in therapeutic resistance in colorectal cancer patients. To search for an effective therapeutic protocol is an urgent task. A secondary metabolite in the sponge sp.

Toxicologic Concerns with Current Medical Nanoparticles.

Nanotechnology is one of the scientific advances in technology. Nanoparticles (NPs) are small materials ranging from 1 to 100 nm. When the shape of the supplied nanoparticles changes, the physiological response of the cells can be very different.

The power of heteronemin in cancers.

Heteronemin (Haimian jing) is a sesterterpenoid-type natural marine product that is isolated from sponges and has anticancer properties. It inhibits cancer cell proliferation via different mechanisms, such as reactive oxygen species (ROS) production, cell cycle arrest, apoptosis as well as proliferative gene changes in various types of cancers. Recently, the novel structure and bioactivity evaluation of heteronemin has received extensive attention.

Heteronemin and tetrac derivatives suppress non-small cell lung cancer growth via ERK1/2 inhibition.

The most common cancer, lung cancer, causes deaths worldwide. Most lung cancer patients have non-small cell lung carcinomas (NSCLCs) with a poor prognosis. The chemotherapies frequently cause resistance therefore search for new effective drugs for NSCLC patients is an urgent and essential issue.

Nano-Strategies Targeting the Integrin αvβ3 Network for Cancer Therapy.

Integrin αvβ3, a cell surface receptor, participates in signaling transduction pathways in cancer cell proliferation and metastasis. Several ligands bind to integrin αvβ3 to regulate proliferation and metastasis in cancer cells. Crosstalk between the integrin and other signal transduction pathways also plays an important role in modulating cancer proliferation.

Role of thyroid hormone-integrin αvβ3-signal and therapeutic strategies in colorectal cancers.

Thyroid hormone analogues-particularly, L-thyroxine (T) has been shown to be relevant to the functions of a variety of cancers. Integrin αvβ3 is a plasma membrane structural protein linked to signal transduction pathways that are critical to cancer cell proliferation and metastasis. Thyroid hormones, T and to a less extend T bind cell surface integrin αvβ3, to stimulate the extracellular signal-regulated kinase 1/2 (ERK1/2) pathway to stimulate cancer cell growth.

High-Grade B-Cell Lymphoma (HGBL) with and and/or Rearrangements Is Predominantly BCL6-Rearranged and BCL6-Expressing in Taiwan.

This study investigated the epidemiological and clinical peculiarities of and rearrangement in patients with high grade B-cell lymphoma (HGBL) from Taiwan, compared with data from Western countries. Two hundred and eighty-two DLBCL cases from Taipei Medical University-affiliated hospitals ( = 179) and Tri-Service General Hospital ( = 103) were enrolled for this study. From the 282, 47 (16.

Inhibition of Bruton's Tyrosine Kinase Suppresses Cancer Stemness and Promotes Carboplatin-induced Cytotoxicity Against Bladder Cancer Cells.

Background/aim: Bruton's tyrosine kinase (BTK) has been discovered to serve a critical role in the survival and infiltration of B-cell lymphoma. Recently, it was reported that BTK inhibitors exerted potential beneficial effects against numerous types of solid tumor, including glioblastoma multiforme and breast cancer; however, whether BTK is crucial for the progression of bladder cancer (BLCA) remains unclear. The present study investigated the in vitro function of BTK in stemness properties of BLCA cells.

Gamma/Delta T-Cells Enhance Carboplatin-induced Cytotoxicity Towards Advanced Bladder Cancer Cells.

Background/aim: Bladder cancer (BLCA, urothelial bladder cancer) is one of the most common malignancies with increasing incidence and mortality worldwide. Poor diagnosis and the limitation of treatment is still an unmet need in clinical practice. γδ T-Cells have been paid increasing attention because of their potent cytotoxicity against tumors.

NDAT Targets PI3K-Mediated PD-L1 Upregulation to Reduce Proliferation in Gefitinib-Resistant Colorectal Cancer.

The property of drug-resistance may attenuate clinical therapy in cancer cells, such as chemoresistance to gefitinib in colon cancer cells. In previous studies, overexpression of PD-L1 causes proliferation and metastasis in cancer cells; therefore, the PD-L1 pathway allows tumor cells to exert an adaptive resistance mechanism in vivo. Nano-diamino-tetrac (NDAT) has been shown to enhance the anti-proliferative effect induced by first-line chemotherapy in various types of cancer, including colorectal cancer (CRC).

Combined Treatment of Heteronemin and Tetrac Induces Antiproliferation in Oral Cancer Cells.

Background: Heteronemin, a marine sesterterpenoid-type natural product, possesses an antiproliferative effect in cancer cells. In addition, heteronemin has been shown to inhibit expression. Our laboratory has demonstrated that the thyroid hormone deaminated analogue, tetrac, activates and induces antiproliferation in colorectal cancer.

Cytokine-induced Killer T Cells Enhance the Cytotoxicity Against Carboplatin-resistant Ovarian Cancer Cells.

Background/aim: Ovarian cancer (OC) is typically diagnosed at an advanced stage with limitations for cure. Cytokine-induced killer (CIK) T cell therapy exerts significant cytotoxic effects against cancer cells and reduces the adverse effects of chemotherapy. Herein, we performed a flow cytometry-based method to evaluate the cytotoxicity of peripheral blood mononuclear cells-derived CIK cells against OC cells.

Integrin αvβ3 in the Mediating Effects of Dihydrotestosterone and Resveratrol on Breast Cancer Cell Proliferation.

Hormones and their receptors play an important role in the development and progression of breast cancer. Hormones regulate the proliferation of breast cancer cells through binding between estrogen or progestins and steroid receptors that may reside in the cytoplasm or be transcriptionally activated as steroid-protein nuclear receptor complexes. However, receptors for nonpeptide hormones also exist in the plasma membrane.
