Transitional cell carcinoma is a malignancy in which a number of single agents with different mechanisms of action are effective. Most older agents have limited activity, but several combinations are quite active. The most common regimens over the past 15 years were cyclophosphamide, doxorubicin, and cisplatin (CAP, CISCA); cisplatin, methotrexate, and vinblastine (CMV, MCV); and (methotrexate, vinblastine, doxorubicin, and cisplatin (M-VAC). Several new agents have been identified recently, including docetaxel, paclitaxel, gemcitabine, and ifosfamide. Combinations using these new agents now provide alternatives to the M-VAC combination that have much less toxicity and, in some instances, are used as multimodality therapy in patients with unresectable primary tumors without the degree of toxicity associated with older combinations of chemotherapy. Phase II and Phase III trials evaluating these new combinations are reviewed.

Background: Endocrine-disrupting chemicals (EDCs) interfere with the endocrine system and negatively impact reproductive health. Biochanin A (BCA), an isoflavone with anti-inflammatory and estrogen-like properties, has been identified as one such EDC. This study investigates the effects of BCA on transcription, metabolism, and hormone regulation in primary human granulosa cells (GCs), with a specific focus on the activation of bitter taste receptors (TAS2Rs).

Background: During mammalian spermatogenesis, the cytoskeleton system plays a significant role in morphological changes. Male infertility such as non-obstructive azoospermia (NOA) might be explained by studies of the cytoskeletal system during spermatogenesis.
Methods: The cytoskeleton, scaffold, and actin-binding genes were analyzed by microarray and bioinformatics (771 spermatogenic cellsgenes and 774 Sertoli cell genes).

The process of viral entry into host cells is crucial for the establishment of infection and the determination of viral pathogenicity. A comprehensive understanding of entry pathways is fundamental for the development of novel therapeutic strategies. Standard techniques for investigating viral entry include confocal microscopy and flow cytometry, both of which provide complementary qualitative and quantitative data.

Clear cell renal cell carcinoma is a prevalent urological malignancy, imposing substantial burdens on both patients and society. In our study, we used bioinformatics methods to select four putative target genes associated with EMT and prognosis and developed a nomogram model which could accurately predicting 5-year patient survival rates. We further analyzed proteome and single-cell data and selected PLCG2 and TMEM38A for the following experiments.

The aberrant vascular response associated with tendon injury results in circulating immune cell infiltration and a chronic inflammatory feedback loop leading to poor healing outcomes. Studying this dysregulated tendon repair response in human pathophysiology has been historically challenging due to the reliance on animal models. To address this, our group developed the human tendon-on-a-chip (hToC) to model cellular interactions in the injured tendon microenvironment; however, this model lacked the key element of physiological flow in the vascular compartment.
