Squamous cell carcinoma is the most common malignancy affecting the sinonasal tract. Local recurrence is the main pattern of treatment failure, affecting nearly half of patients treated for primary sinonasal squamous cell carcinoma (SNSCC). Due to disease rarity and heterogeneity of practices, there are limited guidelines for how to diagnose and care for these patients. This paper reviews current evidence regarding etiology, pathophysiology, diagnosis, prognostic factors, and treatment modalities of recurrent SNSCC (rSNSCC). Currently, salvage surgery offers the only durable approach for eligible patients. These resections often require robust reconstructive options due to prior surgery or radiation. Chemoradiation is offered as an adjuvant or palliative approach when surgery is not a feasible option. Emerging options such as immunotherapy and particle therapy remain an area of ongoing investigation.

Unveiling the role of miRNAs in Diminished Ovarian Reserve: an in silico network approach.
Syst Biol Reprod Med
December 2025
Department of Biosciences and Technology for Food, Agriculture and Environment, University of Teramo, Teramo, Italy.
MicroRNAs (miRNAs) have acquired an increased recognition to unravel the complex molecular mechanisms underlying Diminished Ovarian Reserve (DOR), one of the main responsible for infertility. To investigate the impact of miRNA profiles in granulosa cells and follicular fluid, crucial players in follicle development, this study employed a computational network theory approach to reconstruct potential pathways regulated by miRNAs in granulosa cells and follicular fluid of women suffering from DOR. Available data from published research were collected to create the FGC_MiRNome_MC, a representation of miRNA target genes and their interactions.

Front Biosci (Landmark Ed)
January 2025
Department of Cardiothoracic Surgery, The Affiliated Jiangyin Hospital of Nantong University, 214400 Jiangyin, Jiangsu, China.
Background: This study investigates the role of small ubiquitin-like modifier (SUMO)-specific peptidase 5 (SENP5), a key regulator of SUMOylation, in esophageal squamous cell carcinoma (ESCC), a lethal disease, and its underlying molecular mechanisms.
Methods: Differentially expressed genes between ESCC mouse oesophageal cancer tissues and normal tissues were analysed via RNA-seq; among them, SENP5 expression was upregulated, and this gene was selected for further analysis. Immunohistochemistry and western blotting were then used to validate the increased protein level of SENP5 in both mouse and human ESCC samples.
Thyroid Hormone Activation Regulates the Crosstalk between Breast Cancer and Mesenchymal Stem Cells.
Front Biosci (Landmark Ed)
January 2025
Department of Clinical Medicine and Surgery, University of Naples "Federico II", 80131 Naples, Italy.
Background: Thyroid Hormones (THs) critically impact human cancer. Although endowed with both tumor-promoting and inhibiting effects in different cancer types, excess of THs has been linked to enhanced tumor growth and progression. Breast cancer depends on the interaction between bulk tumor cells and the surrounding microenvironment in which mesenchymal stem cells (MSCs) exert powerful pro-tumorigenic activities.

Front Biosci (Landmark Ed)
January 2025
Department of Cardiovascular Medicine, Binzhou Medical University Hospital, 256603 Binzhou, Shandong, China.
Background: Cellular vacuolization is a commonly observed phenomenon under physiological and pathological conditions. However, the mechanisms underlying vacuole formation remain largely unresolved.
Methods: LysoTracker Deep Red probes and Enhanced Green Fluorescent Protein-tagged light chain 3B (LC3B) plasmids were employed to differentiate the types of massive vacuoles.
Androgenic Anabolic Steroids Cause Thiol Imbalance in the Vascular Endothelial Cells.
Front Biosci (Landmark Ed)
January 2025
Department of Cytobiology and Proteomics, Medical University of Lodz, 92-215 Lodz, Poland.
Background: Androgenic anabolic steroids (AASs) are synthetic drugs structurally related to testosterone, with the ability to bind to androgen receptors. Their uncontrolled use by professional and recreational sportspeople is a widespread problem. AAS abuse is correlated with severe damage to the cardiovascular system, including changes in homeostasis and coagulation disorders.
