SMYD3 drives cell cycle and epithelial-mesenchymal transition pathways through dual gene transcriptional repression and activation in HPV-negative head and neck cancer.

Human papillomavirus (HPV)-negative head and neck squamous cell carcinoma (HNSCC) is the sixth most common cancer type in the world and is associated with an overall poor prognosis. The protein methyltransferase SET and MYND domain-containing 3 (SMYD3), which trimethylates H3K4, activates gene transcription and enhances several oncogenic pathways, including epithelial-mesenchymal transition and cell cycle related pathways, in various cancer types. It was also recently shown that SMYD3 is overexpressed in HPV-negative HNSCC, and represses the expression of type I IFN response genes, contributing to resistance to anti-PD-1 checkpoint blockade in this disease.

Transition from point A to volume based image guided brachytherapy across a network of centers in India through workshop and mentoring.

Aim: To demonstrate how workshop and mentoring across a network of radiotherapy centers helped in transitioning from point A to volume-based image guided brachytherapy in carcinoma cervix.

Materials And Methods: Based on discussion with different centers across the network, the lapses in cervical cancer treatment were identified and a workshop was designed to change the practice pattern. The main focus of the workshop was to streamline EBRT dose prescription protocols and implement volume based image guided brachytherapy through mentoring and hands on training.

Lithium niobate on insulator: an emerging nanophotonic crystal for optimized light control.

Lithium niobate (LN) stands out as a versatile nonlinear optoelectronic material which can be directly applied in tunable modulators, filters, parametric amplifiers, and photonic integrated circuits. Recently, LN photonic crystals have garnered attention as a compelling candidate for incorporation into photonic integrated circuits, showcasing their potential in advancing the field. Photonic crystals possess a widely acknowledged capability to manipulate the transmission of light modes, similar to how nanostructures have been utilized to regulate electron-related phenomena.
