Renal cell carcinoma (RCC) presents as metastatic disease in one third of cases. Research on circulating tumor cells (CTCs) and liquid biopsies is improving the understanding of RCC biology and metastases formation. However, a standardized, sensitive, specific, and cost-effective CTC detection technique is lacking. The use of platforms solely relying on epithelial markers is inappropriate in RCC due to the frequent epithelial-mesenchymal transition that CTCs undergo. This study aimed to test and clinically validate RUBYchip™, a microfluidic label-free CTC detection platform, in RCC patients. The average CTC capture efficiency of the device was 74.9% in spiking experiments using three different RCC cell lines. Clinical validation was performed in a cohort of 18 patients, eight non-metastatic (M0), five metastatic treatment-naïve (M1TN), and five metastatic progressing-under-treatment (M1TP). An average CTC detection rate of 77.8% was found and the average (range) total CTC count was 6.4 (0-27), 101.8 (0-255), and 3.2 (0-10), and the average mesenchymal CTC count (both single and clustered cells) was zero, 97.6 (0-255), and 0.2 (0-1) for M0, M1TN, and M1TP, respectively. CTC clusters were detected in 25% and 60% of M0 and M1TN patients, respectively. These results show that RUBYchip™ is an effective CTC detection platform in RCC.

A critical prerequisite for translating circulating tumor cells (CTCs) detection technologies into clinical practice is achieving high-efficiency capture and non-destructive release of low-abundance CTCs in blood. In recent years, innovative designs and surface modification of bioinspired topological micro/nanostructured materials have provided efficient solutions to capture and release CTCs. Motivated by pollen morphology and multimodal regulation, this study designed pollen-inspired spiky topological magnetic nanoparticles (IP-GSMNs) based on dual-recognition interface and intelligent-response modulation for high-efficiency capture and non-destructive release of CTCs from peripheral whole blood.

Background: Circulating tumor cells (CTCs) are increasingly recognized as a minimally invasive biomarker with significant potential in oncologic monitoring and prognostication. This study aimed to assess the dynamics of CTC levels in patients with rectal cancer undergoing multimodal treatment and evaluate their potential role in therapeutic decision-making.
Methods: We conducted a prospective, observational study of 56 patients with histologically confirmed rectal adenocarcinoma.

The presence of Salmonella species cells in the viable but nonculturable (VBNC) state has been extensively confirmed in both aqueous environments and food systems, posing a significant and often underestimated threat to public health. However, the regulatory mechanisms governing the formation and resuscitation of VBNC Salmonella remain incompletely understood. This study aimed to elucidate the functions of yeaZ in regulating the formation and resuscitation of VBNC Salmonella enteritidis.

Background: Androgen receptor (AR) splice variants (AR-Vs) have emerged as potential resistance mechanisms to AR-targeted agents (ARTAs) in prostate cancer (PC), particularly in the context of castration-resistant disease. Among them, AR-V3 has been frequently detected, yet its biological function remains unclear due to conflicting results from initial studies. This study aimed to comprehensively investigate the molecular structure, activity, and clinical relevance of AR-V3.

Background: Peritoneal metastasis is a leading cause of death in gastric cancer (GC) patients, highlighting the need for early diagnosis and high-risk population identification. While circulating tumor DNA(ctDNA) and circulating tumor cells (CTC) have been widely studied in blood, their role in peritoneal lavage fluid (PLF) remains unexplored.
Methods: Patients with stage III GC were enrolled, and preoperative/postoperative PLF was collected in this study.
