Cervical cancer accounts for the second most frequent cancer and also third leading cause of cancer mortality (15%) among women worldwide. The major problems of chemotherapeutic treatment in cervical cancer are non-specific cytotoxicity and drug resistance. Plant-derived products, known as natural therapies, have been used for thousands of years in cancer treatment with a very low number of side effects. Allium atroviolaceum is a species in the genus Allium and Liliaceae family, which could prove to have beneficial effects on cancer treatment, although there is a lack of corresponding attention...

The ginger rhizome is rich in bioactive compounds, including [6]-gingerol, [8]-gingerol, and [10]-gingerol; however, to date, most research on the anti-cancer activities of gingerols have focused on [6]-gingerol. In this study, we compared [10]-gingerol with [8]-gingerol and [6]-gingerol in terms of their ability to inhibit the growth of human and mouse mammary carcinoma cells. A colorimetric assay based on the enzymatic reduction of 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide revealed that [10]-gingerol was more potent than [6]-gingerol and at least as potent as [8]-gingerol for the inhibition of triple-negative human (MDA-MB-231, MDA-MB-468) and mouse (4T1, E0771) mammary carcinoma cell growth...

Lung cancer is the most common type of malignancy and one of the leading causes of cancer-related deaths in the world. Non-small cell lung carcinomas (NSCLC) account for 85% cases of lung cancer. Sanguinarine (SNG) is a benzophenanthridine alkaloid isolated from plants of the Papaveraceae family that possess diverse biological activities. SNG exhibits antitumor effects in several cancer cells. However, the effects of SAN on NSCLC proliferation, invasion, and migration and the mechanisms remain to be clarified...

BACKGROUND/AIMS: For in vitro cytotoxicity testing, discrimination of apoptosis and necrosis represents valuable information. Viability analysis performed at two different time points post treatment could serve such a purpose because the dynamics of metabolic activity of apoptotic and necrotic cells is different, i.e. a more rapid decline of cellular metabolism during necrosis whereas cellular metabolism is maintained during the entire execution phase of apoptosis. This study describes a straightforward approach to distinguish apoptosis and necrosis...

The protein encoded by immature colon carcinoma transcript 1 (ICT1) is a component of the human mitochondrial ribosome, and is reported to be implicated in cell proliferation, viability and apoptosis of HeLa cells. This study was conducted to investigate the role of ICT1 in human breast cancer. Oncomine database was used to investigate ICT1 expression in human breast cancer tissues compared to normal tissues. The results showed that ICT1 was highly overexpressed in various human breast cancer subtypes. Then short hairpin RNA (shRNA)-mediated knockdown of ICT1 was performed in human breast cancer ZR-75-30 and T-47D cells...

Patients with advanced urothelial carcinoma live 3 months longer, on average, when given pembrolizumab as a second-line treatment instead of chemotherapy. The finding is based on data from the first phase III trial to test an immunotherapeutic in these patients, which could lead to another label indication for the PD-1 inhibitor.

REVIEW
Luca Di Tommaso, Massimo Roncalli
Few tissue markers are currently available to pathologists in the study of hepatocellular tumors. These markers should be used carefully taking into consideration not only morphology but also, and sometimes even more important, the clinical setting where the lesion to be diagnosed had developed. Glypican-3, heat shock protein 70, and glutamine synthetase (GS) are markers currently used, as a single panel, to discriminate the nature of a <2 cm hepatocellular lesion lacking radiological features of hepatocellular carcinoma (HCC) detected in a cirrhotic patient under surveillance...

Importance: Given recently published results of a 750-patient adjuvant sunitinib trial showing improved disease-free survival (DFS), the appropriate strategy for treating high-risk patients is unclear. We sought to determine whether there is improved disease-free survival benefit to taking the active drug in patients with high-risk (pT3, pT4, node-positive) clear cell renal cancer (ccRCC) in the ASSURE trial (adjuvant sunitinib or sorafenib vs placebo in resected unfavorable renal cell carcinoma [RCC]), the largest adjuvant trial published to date...
