Anticancer activity of derived peptide with iRGD in colon cancer therapy.

Objectives: Colon cancer is well-known as a life-threatening disease. Since the current treatment modalities for this type of cancer are powerful yet face some limitations, finding novel treatments is required to achieve better outcomes with fewer side effects. Here we investigated the therapeutic potential of Azurin-p28 alone or along with iRGD (Ac-CRGDKGPDC-amide) as a tumor-penetrating peptide and 5-fluorouracil (5-FU) for colon cancer.

The photocatalytic, cytotoxicity, and antibacterial properties of zinc oxide nanoparticles synthesized using Trigonella foenum-graecum L extract.

In this study, the manufacture of zinc oxide nanoparticles (ZnO-NPs) was completed via the sol-gel method with Trigonella foenum-graecum L extract for the first time to function as the stabilizing and reducing agent. The obtained product was investigated by various analyzing procedures such as TGA/DTG, FT-IR, UV-Vis, XRD, and EDX/FESEM. The calcination of our product was conducted at temperatures of 400, 500, and 600 °C.

Facile green synthesis of Ag-doped ZnO/CaO nanocomposites with Caccinia macranthera seed extract and assessment of their cytotoxicity, antibacterial, and photocatalytic activity.

The current paper exhibited a green method for the manufacture of Ag-doped ZnO/CaO nanocomposites (NCPs) by the usage of Caccinia macranthera seed extract, zinc, calcium, and silver salts solution, for the first time. The chemical structure of NCPs was studied by the FT-IR technique. The XRD pattern shows a crystallite structure with an Fm3m group space and particle size of about 23 nm.

Inhibition of angiotensin pathway via valsartan reduces tumor growth in models of colorectal cancer.

Background: Overexpression of the angiotensin-II receptor and renin-angiotensin system (RAS) has been reported in several malignancies, including colorectal-cancer (CRC), indicating its potential value as a therapeutic target. Here we explored the impact of targeting the RAS using an angiotensin II receptor blocker, valsartan, alone and its combination with Fluorouracil (5-FU) in in vitro and in vivo models of CRC.

Methods: Anti-proliferative activity of valsartan was evaluated in 2-/3-dimensional in vitro and in vivo CRC mouse models.

The therapeutic potential of γ-AlO nanoparticle containing 5-fluorouracil in the treatment of colorectal cancer.

5-Fluorouracil (5-FU) is being used in the treatment of several malignancies, but side effects are often reported and include: diarrhea, vomiting, nausea, poor appetite, watery eyes, and photophobia. We have developed and tested the cytotoxic activity of nanocrystalline powder of γ-alumina (γ-AlO) containing 5-FU in two-dimensional and three-dimensional (3D) CRC cell culture. γ-AlO was prepared using a facile sol-gel method.

Hydrogen-rich water exerts anti-tumor effects comparable to 5-fluorouracil in a colorectal cancer xenograft model.

Background: Colorectal cancer (CRC) is the third leading cause of cancer-related deaths in the world. Tumor removal remains the preferred frontline treatment; however, effective non-surgical interventions remain a high priority. 5-fluorouracil (5-FU) is a widely used chemotherapy agent, and molecular hydrogen (H) has been recognized for its antioxidant and anti-inflammatory effects, with research also suggesting its potential anti-tumor effects.

Angiotensin II Receptor Antagonist, Valsartan, Has Beneficial Effect in Lung Metastasis of Colorectal Cancer Treated with Fluorouracil.

Purpose: Lung metastasis is the main cause of death in patients with colorectal carcinoma (CRC). Angiotensin II has been confirmed to facilitate cancer cell progression and metastasis. In this study, the possible anti-metastatic effects of an angiotensin II receptor type 1 (AT1R) antagonist, valsartan, have been investigated in an experimental CRC lung metastasis model.

Inhibition of angiotensin II type 1 receptor by candesartan reduces tumor growth and ameliorates fibrosis in colorectal cancer.

Colorectal cancer (CRC) is an important cause of cancer-related mortality. Aberrant activation of the renin-angiotensin system (RAS) is reported to be associated with poor clinical outcomes in patients with CRC. This study was designed to explore the anti-tumor effects of the angiotensin receptor blocker Candesartan either alone or in combination with 5-FU in and models of CRC.

The therapeutic potential of losartan in lung metastasis of colorectal cancer.

Colorectal cancer (CRC) is a common cancer with a high incidence rate. Components of the renin-angiotensin system (RAS) have been reported to be dysregulated in several malignancies including CRC. Here, we have explored the potential anti-metastatic effects of a RAS inhibitor, losartan, in an experimental model of lung metastasis in CRC.

The Esophageal Cancer and the PI3K/AKT/mTOR Signaling Regulatory microRNAs: a Novel Marker for Prognosis, and a Possible Target for Immunotherapy.

The Phosphatidylinositol 3-kinase/AKT/Mammalian Target of Rapamycin (PI3K/AKT/mTOR) pathway has a critical regulatory role in cell biology including translation, transcription, and autophagy. Dysregulation of this pathway is involved in the pathogenesis, development, and prognosis of esophageal cancer that has been assessed in the recent years and its potential as a target in therapy. This report summarizes the current knowledge about PI3K/AKT/mTOR pathway and its cross-talk with a focus on the value of targeting this pathway as a potential therapeutic target in the treatment of esophageal cancer.

Apoptosis inducing capacity of Holothuria arenicola in CT26 colon carcinoma cells in vitro and in vivo.

Objectives: Sea cucumber is one of the classes of echinoderms, which is considered as a health marine product and possess various biological characteristics with therapeutic application. The present investigation attempted to evaluate the potential of anti-cancer Persian Gulf sea cucumber species Holothuria arenicola (H. arenicola) aqueous extract on mice colon carcinoma cells in vitro and in vivo.
