Transcriptome analysis of FEN1 knockdown HEK293T cell strain reveals alteration in nucleic acid metabolism, virus infection, cell morphogenesis and cancer development.

CONCLUSION: These findings provide insight into how FEN1 nuclease might regulate a wide variety of biological processes, and laid the foundation for understanding the role other RAD2 family nucleases in cell growth and metabolism. PMID: 31272350 [PubMed - as supplied by publisher]

I was recently in London for the Longevity Week, a collection of single day and evening events organized by investor Jim Mellon of Juvenescence and supporting groups. Varied events focused separately on (a) educating investors in the science of aging, (b) generating a larger investment community for the new longevity industry, and (c) improving the non-profit world and its efforts to explain the merits of treating aging to the public, to bring therapies to the clinic, and to improve the state of older life using presently available tools. Jim Mellon clearly understands that building an industry focused on the medical contr...

BACKGROUND: Reconstruction of the pelvic floor defect caused by extralevator abdominoperineal excision poses a challenge for the surgeon. OBJECTIVE: The aim of this study was to analyze the long-term perineal wound complications in patients undergoing conventional primary closure versus biological mesh–assisted repair after extralevator abdominoperineal excision. DESIGN: This was a single-institution retrospective observational study. SETTINGS: The study was conducted at a tertiary academic medical center. PATIENTS: Patients with low advanced rectal cancer undergoing extralevator abdominoperineal excisi...

To perceive their three-dimensional environment, cells and tissues must be able to sense and interpret various physical forces like shear, tensile, and compression stress. These forces can be generated both internally and externally in response to physical properties, like substrate stiffness, cell contractility, and forces generated by adjacent cells. Mechanical cues have important roles in cell fate decisions regarding proliferation, survival, and differentiation as well as the processes of tissue regeneration and wound repair. Aberrant remodeling of the extracellular space and/or defects in properly responding to mechan...

In this study, we found that CPT1 (Carnitine palmitoyl transferase I) and CPT2 (Carnitine palmitoyl transferase II), a pair of rate-limiting enzymes for mitochondrial fatty acid transportation, play a critical role in increasing fatty acid oxidation (FAO) required for the cellular fuel demands in radioresistant breast cancer cells (RBCs) and radiation-derived breast cancer stem cells (RD-BCSCs). Enhanced CPT1A/CPT2 expression was detected in the recurrent human breast cancers and associated with a worse prognosis in breast cancer patients. Blocking FAO via a FAO inhibitor or by CRISPR-mediated CPT1A/CPT2 gene deficiency in...

Abstract Retrospective analysis has already shown correlation between severe Chronic Periodontitis (CP) cases with human papiloma virus (HPV). Hence, we aimed to explore deep-seated infected granulation tissue removed during periodontal flap surgery procedures for residential bacterial species between HPV+ and HVP- CP cases, which may serve as good predisposition marker for oral cancer. All CP-granulation samples showed the prominence of Firmicutes, Proteobacteria, and Bacteroidetes phyla with an abundance of gram negative anaerobes, except Streptococcus. In Beta diversity nonmetric multidimensional scaling plot, ...

ConclusionWe demonstrated newly developed MSI-NGS with MSIcall accurately determines the MSI status of FFPE tumor tissues thorough sequencing of tumor samples alone without patient-matched normal controls. This approach could be applied to all types of solid tumors to determine responders to immune-oncology therapy.

Abstract Therapeutic strategies designed to tinker with cancer cell DNA damage response have led to the widespread use of PARP inhibitors for BRCA1/2-mutated cancers. In the haematological cancer multiple myeloma, we sought to identify analogous synthetic lethality mechanisms that could be leveraged upon established cancer treatments. The combination of ATR inhibition using the compound VX-970 with a drug eliciting interstrand cross-links, melphalan, was tested in in vitro, ex vivo, and most notably in vivo models. Cell proliferation, induction of apoptosis, tumor growth and animal survival were assessed. The comb...

We report the case of a Lynch syndrome patient with metastatic CRC and urothelial cancer who was treated sequentially with pembrolizumab (targeting PD1), atezolizumab (targeting PD‐L1), brief rechallenge with pembrolizumab, and finally the combination of ipilimumab (targeting CTLA‐4) and nivolumab (targeting PD1). Over a 28‐month period the patient experienced prolonged disease control with each different regimen the first time it was given, including metabolic response by positron emission tomography and computed tomography scanning and tumor marker reductions. The case suggests that some patients with advanced MMR...
