The vast body of literature regarding human telomere maintenance is a true testament to the importance of understanding telomere regulation in both normal and diseased states. In this review, our goal was simple: tell the telomerase story from the biogenesis of its parts to its maturity as a complex and function at its site of action, emphasizing new developments and how they contribute to the foundational knowledge of telomerase and telomere biology.

Non-small cell lung cancer (NSCLC), half of which are lung adenocarcinoma (LUAD), is one of the most widely spread cancers in the world. Telomerase, which maintains telomere length and chromosomal integrity, enables cancer cells to avoid replicative senescence. When telomerase is inhibited, cancer cells' senescence began, preventing them from growing indefinitely.

An embryo culture medium is a specialized set of ambient conditions, technological equipment, and nutrients that embryos require to grow properly. We aimed to investigate the , , and gene expression differences between developing and non-developing embryos in spent embryo culture medium. , , and gene expressions were determined from the spent embryo culture medium containing developing and non-developing embryos of 20 normoresponder patients admitted to the Bahçeci Umut IVF Center.

Background: Telomere maintenance is an important feature of tumor cells. Telomeric-repeat binding factor 1 interaction nuclear protein 2 (TIN2), a key member of the shelterin proteins, functions in regulating telomere structure, length and function. Our work sought to investigate the role of TIN2 in controlling gastric cancer (GC) malignant biological behaviors.

Shelterin is composed of six proteins (TRF1, TRF2, TIN2, TPP1, POT1 and RAP1) that can assemble into various subcomplexes . However, the stoichiometry of the shelterin complex and its dynamic association with telomeres in cells is poorly defined.

Unlike most species that use telomerase for telomere maintenance, many dipterans, including , rely on three telomere-specific retrotransposons (TRs)-, , and -to form tandem repeats at chromosome ends. Although TR transcription is crucial in their life cycle, its regulation remains poorly understood. This study identifies the Mediator complex, E2F1-Dp, and Scalloped/dTEAD as key regulators of TR transcription.
