Shining Light On The Invisible: Fluorescent Detection Of Reactive Oxygen Species, Alex Zuo

Research Colloquium

Background: Reactive oxygen species (ROS) are highly reactive molecules essential for various biological processes such as cell signaling and homeostasis. However, excessive ROS production leads to oxidative stress, contributing to diseases like cancer, neurodegenerative disorders, and cardiovascular conditions. Traditional ROS detection methods lack sensitivity, specificity, and real-time spatial-temporal resolution. Recently, fluorescent probes have emerged as powerful tools for detecting and visualizing ROS in biological systems. These probes emit fluorescence upon reacting with specific ROS, allowing precise localization and quantification. Understanding ROS fluctuations during hypoxia and reoxygenation is crucial, especially in skeletal muscle cells. This study explores the dynamics of ROS …

Piperine Encourages Apoptosis In Human Cervical Adenocarcinoma Cells Through Ros Generation, Dna Fragmentation, Caspase-3 Activation And Cell Cycle Arrest, Asif Jafri, Juhi Rais, Sudhir Kumar, Md Arshad

Research Symposium

Background: Cancer is one of the most common destructive diseases and the second leading cause of death in humans. Among cancer, cervical cancer is the second most common malignancy among women globally. Thus, there is a continuous need to search for chemotherapeutic chemicals or naturally occurring drugs to resolve this global health problem. Piperine (1-piperoylpeperdine) is present in the fruits of black pepper (Piper nigrum Linn.) and long pepper (Piper longum Linn.). It possesses several pharmacological properties and in the present study we have evaluated its anti-cancer potential on human cervical adenocarcinoma (HeLa) cells.

Methods: The anti-proliferative effect …

Molecular Basis For The Pharmacological Activities Of Piperlongumine Against Breast Cancer: Role Of Glucose Import, Ros, Nf-Κb And Lncrnas, Nikee Awasthee, Anusmita Shekher, Vipin Rai, Sumit Singh Verma, Shruti Mishra, Subash Chandra Gupta

Research Symposium

Background: Piperlongumine (PL, piplartine) is an alkaloid derived from the Piper longum L. (long pepper) root. The activities PL against breast cancer and the underlying mechanism is not thoroughly investigated.

Aim: We examined the anti-cancer activities of PL against breast cancer cells. The molecular basis for the pharmacological activities of this alkaloid was also examined.

Methods: The breast cancer cell lines such as MCF-7, T-47D, MDA-MB-231, MDA-MB-468 and MDA-MB-453 were used during the study. We used MTT assay, clonogenic and soft agar colony formation assay for cytotoxicity. The cell cycle analysis, phosphatidylserine externalization assay, measurement of mitochondrial membrane potential, …

International Conference On Cancer Health Disparities, Juhi Rais, Asif Jafri, Neelam Shivnath, Habiba Khan, Md Arshad

Research Symposium

Background: Biochanin A, an isoflavone that is mainly present in red clover, has potent chemopreventive properties against many cancers. Ovarian carcinoma is fifth most common and deadliest gynaecological malignancy that causes the highest mortality in females worldwide. Hence a substantial need for new therapies for combating this gynaecological malignancy arises.

Methods: The present study aimed to investigate anti-cancerous potentials of biochanin A on cultured human ovarian carcinoma PA-1 cells through the cell viability assay, cellular apoptosis, disruption of mitochondrial membrane potential (MMP), involvement of ROS, cell cycle kinetics, and expression of apoptosis-related genes namely, p53, Bax, Bcl-2, Noxa and Puma. …

Immunepotent Crp Enhances Cyclophosphamide-Induced Cytotoxicity Through A Caspase Independent But Ros Dependent Mechanism In Triple Negative-Breast Cancer Cells, Ana L. Rivera, A. C. Martínez-Torres, C. Rodríguez-Padilla

Research Symposium

Background: Breast cancer (BC) is one of the leading causes of cancer death worldwide. Cyclophosphamide (CYP) remains a mainstay in cancer therapy mainly in the triple negative breast cancer subtype (TNBC) in spite of harmful adverse effects and cell death-resistances. To face this, combination of chemotherapies and immunotherapies has been proposed. IMMUNEPOTENT CRP (ICRP) is an immunotherapy that has cytotoxic effects in several cancer cells without affecting peripheral blood mononuclear cells (PBMC) and CD3+ cells, beside improving clinical parameters of chemotherapy-treated patients. The aim of this study was to evaluate the mechanism of cytotoxicity induced by ICRP in combination with …

Cyclophosphamide And Epirubicin Induce Apoptotic Cell Death In Microglia Cells, Rafael De La Hoz-Camacho

Research Symposium

Background. Chemotherapy Related Cognitive Impairment’s (CRCI), diminish patient’s quality life, being breast cancer (BC) patients the most affected. Microglia is described to play a major role in CRCI; hence, the aim of this research was to describe the cytotoxicity of cyclophosphamide (CTX) and Epirubicin (EPI), on microglia (SIM-A9), compared to BC cells (4T1).

Methods. We assessed cell viability (Resazurin) and cell death (AnnV), as well as nuclear damage with γ-H2AX, p53, p16 and cell cycle analysis (PI staining) by flow cytometry (FC). Furthermore, we evaluated ΔΨm (DIOC6), ROS (DCFDA) and NO (DAF-FM) production. Finally, caspase activation (TF2-VAD-FMK) and autophagy (CYTO-ID). …

Computational Studies Of Novel Thiazolidine-4-One Based Mao Inhibitors As Neuro-Protective Anti-Parkinson Agents, Abhimannu Shome, Pooja Chawla

Research Symposium

Now a day’s Neurodegenerative diseases such as Parkinson disease is a big concern in the field of medical sciences. In Parkinson’s disease, neurodegeneration occurs in several ways. Monoamine oxidase enzyme is one of them. MAO oxidize the dopamine into its precursor 3,4-dihydroxyphenylacetic acid (DOPAC), which leads to increased ROS and decreased dopamine level. Thiazolidine-4-one pharmacophore has been used to design the desired compound for the target. Thiazolidine-4-one derivatives have been reported to possess anti-oxidant property so the thiazolidine-4-one clubbed compounds were designed and studied via Molecular docking via AutoDock vina, drug-likeness profile by swissADME and pharmacophore modelling through Pharmagist …
