Newly synthesized 2-(2-((1-indol-5yl)methylene)-hydrazinyl)-thiazole derivatives were evaluated for their in vitro cytotoxicity on two carcinoma cell lines A2780 and HeLa. Significant cytotoxic activity for 2-(2-((1-indol-5-yl)methylene)hydrazinyl)-4-methylthiazole () and 2-(2-((1-indol-5-yl)methylene)hydrazinyl)-4-phenylthiazole (), on both A2780 [IC: 11.6 μM (), and 12.4 μM ()] and HeLa [IC: 22.4 μM () and 19.4μM ()] cell lines is reported. Their antioxidant potential was evaluated by spectrophotometric method, using DPPH radical or Fe (TPTZ) complex, and EPR spectroscopy, therefore the compounds and showed remarkable antioxidant activity simultaneously with a cytotoxic effect on A2780 and HeLa cell lines. Furthermore, based on theoretical quantum chemical calculation, the present study analyzed the chemoselectivity of the hydrogen extraction from the indolyl-hydrazinil-thiazoles in reaction with free radicals.

Glutaraldehyde functionalized reduced graphene oxide based resistive sensors for detection of PCA3.
J Mater Chem B
January 2025
Department of Electrical, Electronics and Communication Engineering, Indian Institute of Technology Dharwad, Karnataka - 580011, India.
Prostate cancer antigen 3 (PCA3) has emerged as a critical biomarker for the early detection of prostate cancer, complementing the traditional prostate-specific antigen (PSA) testing. This research presents a novel resistive sensor based on reduced graphene oxide (RGO) functionalized with glutaraldehyde (GA)/complementary single-stranded DNA (ss-DNA) for the detection of the PCA3 RNA. The device was meticulously characterized at each fabrication step to confirm the successful integration of the various layers on the sensor device, utilizing atomic force microscopy (AFM) which confirmed the increase in the thickness of the sensor from ∼1.

Department of Respiratory and Critical Care Medicine, Chest Hospital Affiliated to Shanghai Jiao Tong University, Shanghai, P. R. China.
Background: The prognosis for non-small cell lung cancer (NSCLC) patients treated with standard platinum-based chemotherapy was suboptimal, with safety concerns. Following encouraging results from a preliminary phase I study, this phase II trial investigated the efficacy and safety of first-line sintilimab and anlotinib in metastatic NSCLC.
Methods: In this open-label, randomized controlled trial (NCT04124731), metastatic NSCLC without epithelial growth factor receptor (EGFR), anaplastic lymphoma kinase (ALK), or proto-oncogene tyrosine-protein kinase ROS (ROS1) mutations, and previous treatments for metastatic disease were enrolled.
Molecular Mechanisms of circKIF4A in Breast Cancer Progression.

Department of Thyroid and Breast Surgery, The Second Affiliated Hospital of Guangdong Medical University, Zhanjiang, China.
Aim: Breast cancer (BC) is the most frequently diagnosed malignancy worldwide, necessitating continued research into its molecular mechanisms. Circular RNAs (circRNAs) are increasingly recognized for their role in various cancers, including BC. This study explores the role of circRNA kinesin family member 4A (circKIF4A) in BC progression and its underlying molecular mechanisms.

Cystic fibrosis (CF) is caused by mutations in the (). While gene therapy holds promise as a cure, the cell-type-specific heterogeneity of expression in the lung presents significant challenges. Current CF ferret models closely replicate the human disease phenotype but have limitations in studying functional complementation through cell-type-specific CFTR restoration.

Epidermal growth factor (EGF) binds with its surface receptor to stimulate gene expression and cancer cell proliferation. EGF stimulates cancer cell growth via phosphoinositide 3‑kinase (PI3K) and programmed cell death ligand 1 (PD‑L1) pathways. As an integrin αvβ3 antagonist, heteronemin exhibits potent cytotoxic effects against cancer cells.
