Laryngeal carcinoma is the most common site of malignancy in head and neck region worldwide. Surgical options are limited in cases of laryngeal malignancy and moajority of cases are treated with chemoradiotherapy. Targeted therapy is an evolving novel approach to treat laryngeal carcinoma. The study was conducted to evaluate the role of PTEN, EGF and HER2 in early glottic squamous cell carcinoma cases. 52 samples of early glottis carcoinoma were collected in UCMS and GTB hospital, New Delhi after patients had undergone CO laser excision at the centre. Histopathologic and IHC examination was conducted on the specimen for PTEN, EGFR and HER2 molecules. PTEN was negative in 82.69% cases compared to the stroma with three year local control rate of 72.09%. EGFR was positive in 67.31% samples with three year local control rate of 68.57%. HER2 was negative in all the samples. PTEN and EGFR can be used as prognostic markers as well as novel agents for targeted therapy in the future.

The intracellular protozoan Toxoplasma gondii manipulates host cell signaling to avoid targeting by autophagosomes and lysosomal degradation. Epidermal Growth Factor Receptor (EGFR) is a mediator of this survival strategy. However, EGFR expression is limited in the brain and retina, organs affected in toxoplasmosis.

The scorpion Karsch is edible and has been an essential resource in traditional Chinese medicine for treating numerous diseases. In this study, two small peptides from hydrolysates were examined to elucidate their potential against gastric cancer. The small peptides (AK and GK) were identified using the LC-QTOF-MS-based approach.

Glioblastoma (GBM) is an aggressive brain tumor characterized by extensive metabolic reprogramming that drives tumor growth and therapeutic resistance. Key metabolic pathways, including glycolysis, lactate production, and lipid metabolism, are upregulated to sustain tumor survival in the hypoxic and nutrient-deprived tumor microenvironment (TME), while glutamine and tryptophan metabolism further contribute to the aggressive phenotype of GBM. These metabolic alterations impair immune cell function, leading to exhaustion and stress in CD8+ and CD4+ T cells while favoring immunosuppressive populations such as regulatory T cells (Tregs) and M2-like macrophages.

Environmental endocrine disruptor chemicals (EDCs) have raised significant concerns due to their potential adverse effects on human health, particularly on the central nervous system (CNS). This study provides a comparative analysis of the effects of 17-alpha ethinyl estradiol (EE2) and diethyl phthalate (DEP) on neuronal cell proliferation and neurotoxicity. Using differentiated SH-SY5Y human neuronal cells, we evaluated cell viability, microRNA (miRNA) regulation, and RNA expression following exposure to subtoxic concentrations of EE2 and DEP.

Glioblastoma is the most frequent and malignant primary brain tumor. Although the survival is generally dismal for glioblastoma patients, risk stratification and the identification of high-risk subgroups is important for prompt and aggressive management. The G1-G7 molecular subgroup classification based on the MAPK pathway activation has offered for the first time a non-redundant, all-inclusive classification of adult glioblastoma.
