Various epidemiological and preclinical studies have already established the cancer chemopreventive potential of naturally occurring glucosinolate breakdown product Indole-3-Carbinol (I3C) as well as its abilities to induce selective cell death towards malignant cell. Therefore, the objective of the present study is to improve the therapeutic efficacy and prevention of doxorubicin (DOX)-induced toxicity, by the concurrent use of Indole-3-Carbinol (I3C). In this study, I3C was administered (20 mg/kg b.w., p...

Breast cancer patients who initially respond to cancer therapies often succumb to distant recurrence of the disease. It is not clear why people with the same type of breast cancer respond to treatments differently; some escape from dormancy and relapse earlier than others. In addition, some tumor clones respond to immunotherapy while others do not. We investigated how autophagy plays a role in accelerating or delaying recurrence of neu-overexpressing mouse mammary carcinoma (MMC) following adriamycin (ADR) treatment, and in affecting response to immunotherapy...

The complex nature of marine biodiversity is partially responsible for the lack of studies in Indian ascidian species, which often target a small number of novel biomolecules. We performed untargeted metabolomics using gas chromatography-mass spectrometry (GC-MS) in two invasive ascidian species to investigate the inter-specific chemical diversity of Phallusia nigra and P. arabica in search of drug-like properties and metabolic pathways. The chemical profiling of individual ascidian species was obtained using GC-MS, and the metabolites were determined by searching in NIST library and literature data...

In an effort to develop potent anticancer agents, the synthesis of a series of benzothiazole-based 1,3,4-thiadiazole derivatives (1-14) was described and their cytotoxic effects on A549 human lung adenocarcinoma, MCF-7 human breast adenocarcinoma, HepG2 human hepatocellular carcinoma and NIH/3T3 mouse embryonic fibroblast cell lines were investigated using MTT assay. Phenyl-substituted compounds (8-14) were found to be more effective than naphthyl-substituted compounds (1-7) on cancer cells. Compounds 8, 9, 10, 12, 13 and 14 were identified as the most potent anticancer agents on MCF-7 and HepG2 cell lines and therefore their effects on DNA synthesis and apoptotic/necrotic cell death in MCF-7 cell line were evaluated...

Cancer-associated fibroblasts (CAFs) are major players in the development and spread of breast carcinomas through non-cell-autonomous signaling. These paracrine effects are under the control of several genes and microRNAs. We present here clear evidence that let-7b, a tumor suppressor microRNA, plays key roles in the persistent activation of breast stromal fibroblasts and their functional interplay with cancer cells. We have first shown that let-7b is down-regulated in CAFs as compared to their corresponding normal adjacent fibroblasts, and transient specific let-7b inhibition permanently activated breast fibroblasts through induction of the IL-6-related positive feedback loop...

Cutaneous and intraoral metastasis from any malignancy is not common. Cutaneous spread is usually noted in 5%-10% of high-grade malignancies, as in carcinoma breast, lung, colon, ovary, and malignant melanoma. Only 4.6% cases of cutaneous spread are from renal cell carcinoma (RCC). Intraoral spread from RCC is much rarer with an incidence of approximately 1% of all malignant oral tumors, noted sometimes in tongue, palate, buccal mucosa, gingiva, and lips. RCC is a highly aggressive tumor which requires early diagnosis for increasing the chance of cure...

BACKGROUND: The mediator complex consists of 33 subunits and plays a central role in transcription. Studies have already described the involvement of individual subunits, especially in carcinogenesis. With regard to the subunit MED30, this has, so far, only been confirmed in gastric and breast carcinoma. The role of MED30 in urological tumours is unknown. MATERIALS AND METHODS: First, a database analysis using cBioPortal was performed for the mRNA expression and survival analysis of MED30 in clear cell renal cell carcinoma (ccRCC) and papillary RCC (pRCC)...

Primary breast carcinoma with neuroendocrine features (NEBC) is an uncommon tumor. In the classification of WHO 2012, these tumors were categorized as: 1- neuroendocrine tumor, well-differentiated; 2- neuroendocrine carcinoma, poorly differentiated/small cell carcinoma; and 3- invasive breast carcinoma with neuroendocrine differentiation. In this study, we reviewed NEBC except poorly differentiated/small cell carcinoma variant in order to define the morphological growth patterns and cytonuclear details of these tumors...

The tumor stroma, which accounts for a large part of the tumor mass, represents an attractive target for the delivery of diagnostic and therapeutic compounds. Here, the focus is notably on a subpopulation of stromal cells, known as cancer-associated fibroblasts (CAFs), which are present in more than 90% of epithelial carcinomas including pancreatic, colon and breast cancer. CAFs feature a high expression of fibroblast activation protein (FAP), which is not detectable in adult normal tissue but associated with a poor prognosis in cancer patients...

INTRODUCTION: Suspected thyroid malignancies are usually assumed to be primary in origin. Rarely, in 1-3% of cases, the tumour arises from a secondary source such as a melanoma or breast carcinoma. There is a growing body of research concerning metastatic spread of renal cell carcinoma to the thyroid gland. PRESENTATION OF CASE: This case report describes the presentation and diagnostic work-up of an 84yr male presenting with a goitre and hoarse voice. Histopathological examination of the excised 95 × 65 × 55 mm tissue mass revealed metastatic clear cell renal cell carcinoma...

Invasive papillary carcinoma (IPC) and glycogen-rich clear cell carcinoma (GRCCC) are rare primary breast carcinomas. IPC typically have favorable prognosis, whereas the prognosis of GRCCC is less established. We report a unique case of high-grade invasive mammary carcinoma with mixed IPC and GRCCC features. We review the imaging and pathologic features and discuss prognosis of these unusual breast cancer subtypes.

Background: One of the main causes of mortality is hepatocellular carcinoma (HCC) which accounts for the third leading cause of deaths and one in forty deaths worldwide. The flavonoids, natural antioxidant compounds, account for a major group of polyphenolic compounds. One of the major isoflavones in soybean is genistein (GE) which can inhibit proliferation and induce apoptosis. Isoflavones, major type of phenolic materials, derived from dietary plants and medicinal herbs play a significant role in cancer prevention and treatment...

In a previous study, we evaluated a HER2-specific single domain antibody fragment (sdAb) 2Rs15d labeled with 18 F via conjugation of a residualizing prosthetic agent that was synthesized by copper-catalyzed azide-alkyne cycloaddition (CuAAC). In order to potentially increase overall efficiency and decrease the time required for labeling, we now investigate the use of a strain-promoted azide-alkyne cycloaddition (SPAAC) between the 2Rs15d sdAb, which had been pre-derivatized with an azide-containing residualizing moiety, and an 18 F-labeled aza-dibenzocyclooctyne derivative...

Cutaneous mixed tumor (chondroid syringoma) is the cutaneous counterpart of pleomorphic adenoma of salivary glands, comprised of both epithelial and mesenchymal components. Malignant transformation is exceptionally rare, with only a few cases reported. We report a case of a malignant cutaneous mixed tumor in an 86-year-old white man who presented with a pink indurated plaque on his left scapula. He had a history of nonmelanoma skin cancers, a stage IB malignant melanoma of a lower extremity and Gleason 4 + 3 prostate cancer treated with brachytherapy, external beam irradiation, and bicalutamide...

Purpose: Forkhead box K2 (FOXK2) is a member of the forkhead box family of transcription factors. Recently, researchers discovered that overexpression of FOXK2 inhibits the proliferation and metastasis of breast cancer, non-small cell lung cancer, and colorectal cancer, and is related to the clinical prognosis. However, in hepatocellular carcinoma, FOXK2 results in the opposite phenotypes. Currently, the contribution of FOXK2 to glioma pathogenesis is not clear. Patients and methods: We evaluated the expression of FOXK2 in 151 glioma patients using immunohistochemistry assays...

It is abundantly clear that tumor-derived parathyroid hormone-related protein (PTHrP), receptor activator of nuclear factor-κB ligand (RANKL) and osteoprotegerin (OPG) are central contributors in promoting osteolytic process of breast carcinoma bone metastasis. Forcusing on this molecular basis, the study was undertaken to explore the inhibition effects of total flavonoids from Scutellaria barbata D. Don (TF-SB) on human breast carcinoma bone metastasis. MDA-MB-231 cells and nude mouse models of breast cancer bone metastasis were given TF-SB in different concentrations...

Triple-negative breast cancer is one of the intractable cancers that are not sensitive to treatment with existing molecular-targeted drugs. Recently, there has been much interest in RNA interference-mediated treatment of triple-negative breast cancer. In the present study, we have developed lipid nanoparticles encapsulating siRNA (LNP-siRNA) decorated with an Fab' antibody against heparin-binding EGF-like growth factor (αHB-EGF LNP-siRNA). αHB-EGF LNP-siRNA targeting polo-like kinase 1 (PLK1) was prepared and evaluated for its anticancer effect using MDA-MB-231 human triple-negative breast cancer cells overexpressing HB-EGF on their cell surface...
