The cytotoxic activities of the major diterpene extracted from Salvia multicaulis (Bardakosh) are mediated by the regulation of heat-shock response and fatty acid metabolism pathways in human leukemia cells.

Background: Leukemia is one of the most lethal cancers worldwide and represents the sixth-leading cause of cancer deaths. The results of leukemia treatment have not been as positive as desired, and recurrence is common.

Purpose: Thus, there is an urgent requirement for the development of new therapeutic drugs.

Salvimulticanol from suppresses LPS-induced inflammation in RAW264.7 macrophages: in vitro and in silico studies.

Sustained inflammatory responses can badly affect several vital organs and lead to chronic inflammation-related disorders, such as atherosclerosis, pneumonia, rheumatoid arthritis, obesity, diabetes, Alzheimer's disease, and cancers. is one of the widely distributed plants that contains several biologically active phytochemicals and diterpenoids with anti-inflammatory effects. Therefore, finding alternative and safer natural plant-extracted compounds with good curative anti-inflammatory efficiencies is an urgent need for the clinical treatment of inflammation-related diseases.

Restoring microRNA-34a overcomes acquired drug resistance and disease progression in human breast cancer cell lines via suppressing the ABCC1 gene.

Purpose: Breast cancer is one of the leading types of cancer diagnosed in women. Despite the improvements in chemotherapeutic cure strategies, drug resistance is still an obstacle leading to disease aggressiveness. The small non-coding RNA molecules, miRNAs, have been implicated recently to be involved as regulators of gene expression through the silencing of mRNA targets that contributed to several cellular processes related to cancer metastasis.

Anti-proliferative effect of melatonin in human hepatoma HepG2 cells occurs mainly through cell cycle arrest and inflammation inhibition.

Hepatocellular carcinoma (HCC) is the major lethal primary liver malignant worldwide. Although, melatonin has various antitumor bioactivities; there is a requirement for more investigations to elucidate the not discussed effects, and the controversial responses of the treatment with melatonin on targets mediated in HCC. To achieve the aim of the present study, HCC-HepG2 cells were treated with different concentrations of melatonin at various time intervals.

The diagnostic significance of circulating miRNAs and metabolite profiling in early prediction of breast cancer in Egyptian women.

Objective: Breast cancer (BC) is one of the most commonly diagnosed solid malignancies in women worldwide.

Purpose: Finding new non-invasive circulating diagnostic biomarkers will facilitate the early prediction of BC and provide valuable insight into disease progression and response to therapy using a safe and more accessible approach available every inspection time. Therefore, our present study aimed to investigate expression patterns of potentially circulating biomarkers that can differentiate well between benign, malignant, and healthy subjects.

Importance of immunoglobulin therapy for COVID-19 patients with lymphocytopenia.

Background: The global coronavirus disease 2019 (COVID-19) was announced as pandemic by the World Health Organization (WHO). With the increased number of infected and dead victims daily all over the world, it becomes necessary to stop or overcome its rapid spread.Main bodyAlthough the production of vaccine or even specified effective anti-virus may take about six months to a year, intravenous immunoglobulin (IVIg) may be clinically used as a safe treatment to save and improve the quality of life of patients with a variety of immunodeficiency diseases such as lymphocytopenia, which is a common clinical feature in COVID-19.

Crosstalk between NRF2 and Dicer through metastasis regulating MicroRNAs; mir-34a, mir-200 family and mir-103/107 family.

Oxidative stress due to generation of reactive oxygen species (ROS) can cause damage to cellular proteins, lipids and DNA, which is one of crucial causes responsible for cancer. Nuclear factor erythroid 2 [NF-E2]-related factor 2 (NRF2) is a transcription factor of a variety of antioxidant and cytoprotective enzymes, so that it reduces the levels of damaging ROS in the cell. Over expression of NRF2 in cancer cells can enhance cancer progression, confer resistance to chemo and radiotherapy, and metastasis through the process of epithelial-to mesenchymal transition (EMT); which is a hallmark of cancer-related death.

The Significance of HCV Viral Load in the Incidence of HCC: a Correlation Between Mir-122 and CCL2.

Background: Hepatocellular carcinoma (HCC) is the fifth most common cancer, the third leading cause of cancer deaths worldwide with over 500,000 people affected. It is a major cause of death in patients with chronic hepatitis C virus (HCV) infection. Overwhelming lines of epidemiological evidence have indicated that persistent infection with HCV is a major risk for the development of HCC.

Possible Role of microRNA-122 in Modulating Multidrug Resistance of Hepatocellular Carcinoma.

Hepatocellular carcinoma (HCC) is a hypervascular primary liver cancer characterized by rapid progression, besides, resistance to traditional chemotherapeutic agents. It has been shown that microRNAs play critical roles in regulation of tumor cell sensitivity to drugs through modulating the expression of genes involved in drug transport. The present study investigated whether restoration of miR-122 in HCC cells could alter the cell cycle distribution and the expression of multidrug resistance (MDR)-related genes (ABCB1, ABCC1, ABCG2 and ABCF2).
