Type 3 IP3 receptors: The chameleon in cancer.

Type 3 IP3 receptors: The chameleon in cancer. Int Rev Cell Mol Biol. 2020;351:101-148 Authors: Rosa N, Sneyers F, Parys JB, Bultynck G Abstract Inositol 1,4,5-trisphosphate (IP3) receptors (IP3Rs), intracellular calcium (Ca2+) release channels, fulfill key functions in cell death and survival processes, whose dysregulation contributes to oncogenesis. This is essentially due to the presence of IP3Rs in microdomains of the endoplasmic reticulum (ER) in close proximity to the mitochondria. As such, IP3Rs enable efficient Ca2+ transfers from the ER to the mitochondria, thus regulating metabolism and cell fate. This review focuses on one of the three IP3R isoforms, the type 3 IP3R (IP3R3), which is linked to proapoptotic ER-mitochondrial Ca2+ transfers. Alterations in IP3R3 expression have been highlighted in numerous cancer types, leading to dysregulations of Ca2+ signaling and cellular functions. However, the outcome of IP3R3-mediated Ca2+ transfers for mitochondrial function is complex with opposing effects on oncogenesis. IP3R3 can either suppress cancer by promoting cell death and cellular senescence or support cancer by driving metabolism, anabolic processes, cell cycle progression, proliferation and invasion. The aim of this review is to provide an overview of IP3R3 dysregulations in cancer and describe how such dysregulations alter critical cellular processes such as proliferation or cell death and survival. Here, we pose that the IP3R3 isoform is no...

Study Design.. A meta-analysis. Objective.. The goal of this study was to accurately evaluate the risk ratio (RR) of recurrence in chordoma patients with wide margin after removing the tumors using surgery, compared with inadequate margin (intralesional or marginal). Summary of Background Data.. As a rare malignant bone cancer, the more effective treatment for sacral chordoma is still surgical resection. However, there is no convincing evidence and risk ratio about sacral chordoma patients would be benefit from which kind of surgical margin. Methods.. We searched the PubMed, Cochrane Library, Web of Science, and...

Authors: Carkic J, Nikolic N, Nisevic J, Lazarevic M, Kuzmanovic-Pficer J, Jelovac D, Milasin J Abstract Oral carcinoma is the sixth most common malignancy worldwide, with survival rates of approximately 50%. The major type of oral cancer, present in 90% of the cases, is oral squamous cell carcinoma (OSCC). The genetic background predisposing an individual to OSCC is complex and largely unknown. Studies have suggested that endothelial nitric oxide synthase (eNOS) gene polymorphisms modulate the cancer risk, prompting us to assess the impact of three functional eNOS gene polymorphisms on OSCC risk. The present study...

Purpose of review Genome instability has long been implicated as a primary causal factor in cancer and diseases of aging. The genome is constantly under attack from extrinsic and intrinsic damaging agents. Uracil misincorporation in DNA and its repair is an intrinsic factor resulting in genomic instability and DNA mutations. Additionally, the presence of uracil in DNA can modify gene expression by interfering with promoter binding and transcription inhibition or upregulation of apoptotic proteins. In immune cells, uracil in DNA drives beneficial genomic diversity for antigen-driven immunity. This review addresses disease...

Conclusion: Both ESTD and ESD are safe and effective therapies for early-stage esophageal cancer wider than or equal to one half the esophageal circumference. The dissection speed of ESTD is faster than that of ESD.

CONCLUSION: A hybrid robotic transanal minimally invasive surgery approach allows for complete resection of very large polyps, which would otherwise be extremely challenging with standard transanal approaches. See Video at http://links.lww.com/DCR/B231.

CONCLUSIONS: Nearly all people living with HIV and anal high-grade squamous intraepithelial lesions test positive for high-risk human papillomavirus on anal swabs; negative results may be due to sampling error, L1-based polymerase chain reaction assay, or human papillomavirus types not captured by standard clinical assays. Patients who have human papillomavirus 16-positive anal high-grade squamous intraepithelial lesions are indistinguishable from others based on demographic and clinical characteristics, underscoring the potential role of human papillomavirus testing for anal cancer screening.
