NUAKs promote mTOR/c-Myc-induced glucose and glutamine reprogramming for cell growth and metastasis in breast cancer cells.

Breast cancer progression and metastasis are closely connected to changes in glucose and glutamine metabolism. While Novel (nua) kinase family 1 (NUAK1) and Novel (nua) kinase family 2 (NUAK2), which are two members of the AMPK-related kinases, have been associated with breast tumorigenesis, their role in the metabolic reprogramming that occurs during breast cancer progression remains unclear. Our research uncovers that NUAKs expression is significantly higher in breast cancer tissues and cell lines, and it is positively related to glycolysis, the pentose phosphate pathway (PPP), glutamine metabolism, and a poor prognosis for breast cancer patients.

In silico analysis reveals α-amylase inhibitory potential of Taraxerol () and Epoxywithanolide-1 (): a possible way to control postprandial hyperglycemia-induced endothelial dysfunction and cardiovascular events.

Postprandial hyperglycemia (PPG) exacerbates endothelial dysfunction and impairs vascular function in diabetes as well in healthy people. Though synthetic drugs are available to regulate PPG, the severe gastrointestinal side effects of those medications have prompted the search for alternative treatments. Recently, some phytochemicals captured the attention because of their inhibitory effects on α-amylase to control diabetes.

Density functional theory (DFT) studies were used to study atomic structure and reactivity, including absolute electronegativity (χ), electrophilicity (ω), electron acceptor (ω+), donor capabilities (ω-), electron affinity (EA), energy gap (ΔE), global hardness (η), global softness (S), and ionisation potential (IP) and FMOs, NBOs, MEP, and Mulliken Charge analysis.

Deciphering the molecular landscape of the FAM72 gene family: Implications for stem cell biology and cancer.

Family with sequence similarity 72 (FAM72) is a protein-coding gene family located on chromosome 1 in humans, uniquely featuring four paralogs: FAM72A, FAM72B, FAM72C, and FAM72D. While FAM72's presence as a gene pair with the SLIT-ROBO Rho GTPase-activating protein 2 (SRGAP2) is intriguing, its functional roles, particularly in neural stem cells, remain incompletely understood. This review explores the distinct characteristics of FAM72, shedding light on its expression patterns, potential roles in cell cycle regulation, stem cell renewal and implications in neurogenesis and tumorigenesis.

Hesperetin regulates PI3K/Akt and mTOR pathways to exhibit its antiproliferative effect against colon cancer cells.

Hesperetin, a citrus flavonoid, has been a widely studied anticancer agent against many types of cancers, but the exact mechanism of efficacy is still unrevealed. Therefore, this study has attempted to delineate the mechanical aspect of hesperetin's anticancer efficacy against colon cancer using immunoblotting, scanning, and transmission electron microscopic studies. The treatment with hesperetin (25 and 50 µM) has significantly (p < 0.

Optimizing 2-furylated imidazole π-bridges for NIR lipid droplet imaging.

Lipid droplets (LDs) are globular biological organelles found in the human body, essential for lipid storage, homeostasis, energy reserve, cellular stress response, membrane biogenesis, and cellular signaling. Dysregulated accumulation of LDs leads to various diseases, including breast and liver cancers. Therefore, the development of diagnostic tools for monitoring LDs using suitable probes for bio-imaging applications is imperative.

Digital nets conformational sampling (DNCS) - an enhanced sampling technique to explore the conformational space of intrinsically disordered peptides.

We propose digital nets conformational sampling (DNCS) - an enhanced sampling technique to explore the conformational ensembles of peptides, especially intrinsically disordered peptides (IDPs). The DNCS algorithm relies on generating history-dependent samples of dihedral variables using bitwise XOR operations and binary angle measurements (BAM). The algorithm was initially studied using met-enkephalin, a highly elusive neuropeptide.

Impact of Crystallite Size and Phase Boundaries on Magnetic and Thermoelectric Properties of Cu-Added BiFeO.

In this study, bismuth ferrite (BFO) and copper-added BFO were synthesized using the coprecipitation method. The incorporation of copper into the BFO lattice led to a reduction in the phase percentage of BFO due to the early formation of CuBiO. X-ray diffraction analysis revealed a decrease in crystallite size up to 0.

Synthesis of Indolo[2,3/3,2-]quinoline through Complementary PIDA/BF·OEt as Well as Pd(0)-Mediated Intramolecular Cyclization of Isomeric -((Aryl)--(phenylsulfonyl)indolyl)methylbenzenesulfonamides.

Herein, a straightforward facile synthesis of indolo[2,3-]quinoline analogues was reported from 2-arylamino(phenylsulfonyl)methylindoles involving PIDA/BF·OEt-mediated intramolecular dehydrogenative coupling (IDC) as a key step. Even though isomeric 3-arylamino(phenylsulfonyl)methylindoles, upon interaction with PIDA/BF·OEt, led to complications, synthesis of the indolo[3,2-]quinoline framework could be easily achieved from -(2-iodoaryl)--indolylmethylbenzenesulfonamide by employing a Pd(0)-mediated intramolecular cyclization reaction. Under identical conditions, synthesis of indolo[2,3-]quinolines was also accomplished from the respective -(2-iodoaryl)--indolylmethylbenzenesulfonamides.
