Cannabidiol Inhibits Tumorigenesis in Cisplatin-Resistant Non-Small Cell Lung Cancer via TRPV2.

Chemotherapy forms the backbone of current treatments for many patients with advanced non-small-cell lung cancer (NSCLC). However, the survival rate is low in these patients due to the development of drug resistance, including cisplatin resistance. In this study, we developed a novel strategy to combat the growth of cisplatin-resistant (CR) NSCLC cells.

Slit2 Inhibits Breast Cancer Metastasis by Activating M1-Like Phagocytic and Antifibrotic Macrophages.

Tumor-associated macrophages (TAM) are heterogeneous in nature and comprise antitumor M1-like (M1-TAM) or pro-tumor M2-like (M2-TAM) TAMs. M2-TAMs are a major component of stroma in breast tumors and enhance metastasis by reducing their phagocytic ability and increasing tumor fibrosis. However, the molecular mechanisms that regulate phenotypic plasticity of TAMs are not well known.

Racially Disparate Expression of mTOR/ERK-1/2 Allied Proteins in Cancer.

Recent studies revealed that ethnic differences in mechanistic target of rapamycin (mTOR) and extracellular signal-regulated kinase (ERK-1/2) signaling pathways might be associated with the development and progression of different human malignancies. The African American (AA) population has an increased rate of cancer incidence and mortality compared to the Caucasian American (CA) population. Although the socioeconomic differences across different ethnic groups contribute to the disparity in developing different cancers, recent scientific evidence indicates the association of molecular and genetic variations in racial disparities of different human malignancies.

Lipopolysaccharide from the commensal microbiota of the breast enhances cancer growth: role of S100A7 and TLR4.

The role of commensal bacterial microbiota in the pathogenesis of human malignancies has been a research field of incomparable progress in recent years. Although breast tissue is commonly assumed to be sterile, recent studies suggest that human breast tissue may contain a bacterial microbiota. In this study, we used an immune-competent orthotopic breast cancer mouse model to explore the existence of a unique and independent bacterial microbiota in breast tumors.

Molecular and Cellular Factors Associated with Racial Disparity in Breast Cancer.

Recent studies have demonstrated that racial differences can influence breast cancer incidence and survival rate. African American (AA) women are at two to three fold higher risk for breast cancer than other ethnic groups. AA women with aggressive breast cancers show worse prognoses and higher mortality rates relative to Caucasian (CA) women.

An AI-based approach in determining the effect of meteorological factors on incidence of malaria.

This study presents the classification of malaria-prone zones based on (a) meteorological factors, (b) demographics and (c) patient information. Observations are performed on extended features in dataset over the spiking and non-spiking classifiers including Quadratic Integrate and Fire neuron (QIFN) model as a benchmark. As per research studies, parasite transmission is highly dependent on the (i) stagnant water, (ii) population of area and the (iii) greenery of the locality.

Cancer data classification using binary bat optimization and extreme learning machine with a novel fitness function.

Cancer classification is one of the crucial tasks in medical field. The gene expression of cells helps in identifying the cancer. The high dimensionality of gene expression data hinders the classification performance of any machine learning models.

A new backpropagation neural network classification model for prediction of incidence of malaria.

Malaria is an infectious disease caused by parasitic protozoans of the Plasmodium family. These parasites are transmitted by mosquitos which are common in certain parts of the world. Based on their specific climates, these regions have been classified  as low and high risk regions using a backpropagation neural network (BPNN).

Silymarin, a polyphenolic flavonoid impede growth through interaction with heme.

A polyphenolic flavonoid, Silymarin isolated from is widely known for its hepatoprotective action. In the present study anti-plasmodial activity of Silymarin has been demonstrated for the first time having IC of 14 ± 0.33 μM against the NF-54 strain of with high selectivity index (>100).

Isoniazid induces apoptosis: Role of oxidative stress and inhibition of nuclear translocation of nuclear factor (erythroid-derived 2)-like 2 (Nrf2).

Aims: Long-term treatment of Isoniazid (INH) in tuberculosis (TB) patients can lead to anti-tuberculosis drug-induced hepatotoxicity. To understand the mechanism of hepatotoxicity, an attempt has been made to elucidate the role of Nrf2, a transcription factor induced by oxidative stress, in INH induced apoptosis liver cancer cell lines.

Materials And Methods: Cytotoxicity was evaluated by MTT assay.

Novel combination of salinomycin and resveratrol synergistically enhances the anti-proliferative and pro-apoptotic effects on human breast cancer cells.

Resveratrol (RES) is a natural polyphenol having anti-proliferative activity against breast cancer cells. RES in combination with other chemo modulatory agents, minimizes toxicity and increases efficacy of the treatment. Salinomycin (SAL), a monocarboxylic polyether ionophore is known for selectively targeting breast cancer stem cells.

Isoniazid prevents Nrf2 translocation by inhibiting ERK1 phosphorylation and induces oxidative stress and apoptosis.

Isoniazid is used either alone or in combination with other drugs for the treatment of tuberculosis. It is also used for the prevention of tuberculosis. Chronic treatment of Isoniazid may cause severe liver damage leading to acute liver failure.

Moxifloxacin-loaded nanoemulsions having tocopheryl succinate as the integral component improves pharmacokinetics and enhances survival in E. coli-induced complicated intra-abdominal infection.

In the present work, a novel nanoemulsion laden with moxifloxacin has been developed for effective management of complicated intra-abdominal infections. Moxifloxacin nanoemulsion fabricated using high pressure homogenization was evaluated for various pharmaceutical parameters, pharmacokinetics (PK) and pharmacodynamics (PD) in rats with E. coli-induced peritonitis and sepsis.

Rosiglitazone induces cardiotoxicity by accelerated apoptosis.

Present investigation explores the cardiotoxicity of rosiglitazone (ROSI) using rat heart cardiomyocytes and db/db mice. In H9c2 cells, ROSI at 50 and 60 μM induced an increase in the percentage of apoptotic cells and superoxide generation, along with an increase in the expression of various subunits of NADPH oxidase and nitric oxide synthases, confirmed that ROSI-induced apoptosis in H9c2 cells is by ROS generation. The increase in the expression of the antioxidants like superoxide dismutase (SOD), catalase, glutathione reductase (GR), glutathione-S-transferase (GST), and glutathione peroxidase (GPx) further confirmed this notion.
