Exosomal long non-coding RNAs in cancer: Interplay, modulation, and therapeutic avenues.

In the intricate field of cancer biology, researchers are increasingly intrigued by the emerging role of exosomal long non-coding RNAs (lncRNAs) due to their multifaceted interactions, complex modulation mechanisms, and potential therapeutic applications. These exosomal lncRNAs, carried within extracellular vesicles, play a vital partin tumorigenesis and disease progression by facilitating communication networks between tumor cells and their local microenvironment, making them an ideal candidates for use in a liquid biopsy approach. However, exosomal lncRNAs remain an understudied area, especially in cancer biology.

In Silico Bioinformatics Analysis on the Role of Long Non-Coding RNAs as Drivers and Gatekeepers of Androgen-Independent Prostate Cancer Using LNCaP and PC-3 Cells.

Prostate cancer (PCa) is the leading cancer in men globally. The association between PCa and long non-coding RNAs (lncRNAs) has been reported. Aberrantly expressed lncRNAs have been documented in each of the cancer "hallmarks".

Production and Limbal Lineage Commitment of Aniridia Patient-Derived Induced Pluripotent Stem Cells.

Congenital aniridia is caused by heterozygous mutations on the PAX6 gene leading to reduced amount of PAX6 protein (haploinsufficiency), abnormal eye development, and aniridia-associated keratopathy (AAK). This progressive corneal opacification resembles late-onset limbal stem cell (LSC) deficiency, leading to disrupted corneal epithelial renewal. The factors leading to AAK are not known and defects in native LSC differentiation and/or features leading to ocular surface dysfunction like inflammation and loss of innervation could contribute to development of AAK.

A novel EGFR inhibitor, HNPMI, regulates apoptosis and oncogenesis by modulating BCL-2/BAX and p53 in colon cancer.

Background And Purpose: Colorectal cancer (CRC) is the second most lethal disease, with high mortality due to its heterogeneity and chemo-resistance. Here, we have focused on the epidermal growth factor receptor (EGFR) as an effective therapeutic target in CRC and studied the effects of polyphenols known to modulate several key signalling mechanisms including EGFR signalling, associated with anti-proliferative and anti-metastatic properties.

Experimental Approach: Using ligand- and structure-based cheminformatics, we developed three potent, selective alkylaminophenols, 2-[(3,4-dihydroquinolin-1(2H)-yl)(p-tolyl)methyl]phenol (THTMP), 2-[(1,2,3,4-tetrahydroquinolin-1-yl)(4-methoxyphenyl)methyl]phenol (THMPP) and N-[2-hydroxy-5-nitrophenyl(4'-methylphenyl)methyl]indoline (HNPMI).

Mitochondrial complex III bypass complex I to induce ROS in GPR17 signaling activation in GBM.

Guanine nucleotide binding protein (G protein) coupled receptor 17 (GPR17) plays crucial role in Glioblastoma multiforme (GBM) cell signaling and is primarily associated with reactive oxidative species (ROS) production and cell death. However, the underlying mechanisms by which GPR17 regulates ROS level and mitochondrial electron transport chain (ETC) complexes are still unknown. Here, we investigate the novel link between the GPR17 receptor and ETC complex I and III in regulating level of intracellular ROS (ROSi) in GBM using pharmacological inhibitors and gene expression profiling.

Computational Analysis of miRNA and their Gene Targets Significantly Involved in Colorectal Cancer Progression.

Background: Globally, colorectal cancer (CRC) is the third most common cancer in women and the fourth most common cancer in men. Dysregulation of small non-coding miRNAs have been correlated with colon cancer progression. Since there are increasing reports of candidate miRNAs as potential biomarkers for CRC, this makes it important to explore common miRNA biomarkers for colon cancer.

Aberrantly Binding microRNAs and their Interactions with Nuclear Hormone Receptors.

History: Nuclear Hormone Receptors (NHRs) are the most important targets that play vital role in cellular signaling pathways of disease. Regulation of NHRs by using potential non-coding RNAs, miRNA, is clinically important to control a disease. However, the detailed status of miRNA interactions with NHRs remains unclear.

Data set of induced alterations in tear proteome: Understanding the pathogen-induced host response to fungal infection.

Fungal keratitis is one of the leading causes of blindness in the tropical countries affecting individuals in their most productive age. The host immune response during this infection is poorly understood. We carried out comparative tear proteome analysis of keratitis patients and uninfected controls.

Aspergillus flavus induced alterations in tear protein profile reveal pathogen-induced host response to fungal infection.

Unlabelled: Aspergillus flavus and Fusarium sp. are primary causative agents of keratitis that results in corneal tissue damage leading to vision loss particularly in individuals from the tropical parts of the world. Proteins in the tear film collected from control and keratitis patients was profiled and compared.

Time lapse microscopy observation of cellular structural changes and image analysis of drug treated cancer cells to characterize the cellular heterogeneity.

The effect of Calotropis gigantea latex (CGLX) on human mammary carcinoma cells is not well established. We present the results of this drug activity at total population and single cell level. CGLX inhibited the growth of MCF7 cancer cells at lower IC50 concentration (17 µL/mL).

Nonspecific immune responses of Cathranthus roseus in Oreochromis mossambicus.

The present study was performed to determine the efficacy and immune stimulatory effects of crude and water-soluble leaf fraction of Cathranthus roseus in Oreochromis mossambicus. Intraperitoneal injection method was used to administrate the drugs and Sheep Red Blood Cells (SRBC) which is used as an antigen. Lysozyme assay, plate hole diffusion assay, phytochemical analysis and antimicrobial activity screening methods was used to confirm the drug immune responses.

2,4-dichlorophenoxyacetic acid-induced leaf senescence in mung bean (Vigna radiata L. Wilczek) and senescence inhibition by co-treatment with silver nanoparticles.

Leaf senescence induced by 2,4-dichlorophenoxyacetic acid (2,4-D) and senescence inhibition caused by supplementation with silver (Ag(+)) ions in the form of silver nitrate (AgNO(3)) or silver nanoparticles (AgNPs) were investigated in 8-day-old mung bean (Vigna radiata L. Wilczek) seedlings. Inhibition of root and shoot elongation were observed in mung bean seedlings treated with 500μM 2,4-D.
