Quantum dots are photostable fluorescent semiconductor nanocrystals possessing wide excitation and bright narrow, symmetrical, emission spectra. These characteristics have engendered considerable interest in their application in Multiplex immunohistochemistry for biomarker quantification and co-localisation in clinical samples. Robust quantitation allows biomarker validation, and there is growing need for Multiplex staining due to limited quantity of clinical samples. Most reported multiplexed quantum dot staining used sequential methods that are laborious and impractical in a high-throughput setting. Problems associated with sequential Multiplex staining have been investigated and a method developed using QDs conjugated to biotinylated primary antibodies, enabling Simultaneous multiplex staining with three antibodies. CD34, Cytokeratin 18 and cleaved Caspase 3 were triplexed in tonsillar tissue using an 8 h Protocol, each localised to separate cellular compartments. This demonstrates utility of the method for biomarker measurement enabling rapid measurement of multiple co-localised biomarkers on single Paraffin tissue sections, of importance for clinical trial studies.

The role of vascular endothelial growth factor inhibitors in the treatment of epithelial ovarian cancer

Alexander D. Murphy, Robert D. Morgan, Andrew R. Clamp, Gordon C. Jayson

Summary: Advanced epithelial ovarian, fallopian tube, and primary peritoneal cancers are a leading cause of gynecological cancer-related mortality, with angiogenesis playing a key role in their growth. Vascular endothelial growth factor inhibitors can improve response rate, progression-free survival, and overall survival, regardless of platinum sensitivity in EOC.

Psychosexual Morbidity in Women With Ovarian Cancer: Evaluation by Germline BRCA Gene Mutational Status

Chloe A. Logue, Julia Pugh, Philip Foden, Reem D. Mahmood, Robert D. Morgan, Claire Mitchell, Jurjees Hasan, Andrew R. Clamp, Gordon C. Jayson

Summary: This study aims to assess whether women with gBRCAm ovarian cancer experience distinct psychosexual morbidity. The results showed that women with gBRCAm ovarian cancer were younger and expressed more interest for specialist psychosexual support, and they may have different psychosexual problems compared to women with gBRCAwt ovarian cancer.

BRCA1/2 in non-mucinous epithelial ovarian cancer: tumour with or without germline testing?

Robert D. Morgan, George J. Burghel, Nicola Flaum, Michael Bulman, Philip Smith, Andrew R. Clamp, Jurjees Hasan, Claire L. Mitchell, Zena Salih, Emma R. Woodward, Fiona Lalloo, Emma J. Crosbie, Richard J. Edmondson, Andrew J. Wallace, Gordon C. Jayson, D. Gareth R. Evans

Summary: This study validates the recommendation of testing for BRCA1/2 pathogenic variants in both blood and tumor samples in cases of non-mucinous epithelial ovarian cancer. The findings suggest that reflex tumor BRCA1/2 testing should be performed in all NMEOC cases, and germline BRCA testing may not be necessary for older women without identified tumor BRCA1/2 variants or a family history of specific cancers.

Plasma Tie2 trajectories identify vascular response criteria for VEGF inhibitors across advanced biliary tract, colorectal and ovarian cancers

C. Zhou, J. O'Connor, A. Backen, J. W. Valle, J. Bridgewater, C. Dive, G. C. Jayson

Summary: In this study, it was found that plasma Tie2 (pTie2) can serve as a response biomarker for vascular endothelial growth factor inhibitors (VEGFi) treatment, predicting treatment response and disease progression. By integrating data from different types of cancer, it was demonstrated that pTie2 can guide the optimal use of VEGFi in clinical practice.

Nano-omics: nanotechnology-based multidimensional harvesting of the blood-circulating cancerome

Lois Gardner, Kostas Kostarelo, Parag Mallick, Caroline Dive, Marilena Hadjidemetriou

Summary: Liquid biopsy assays offer opportunities for early detection of cancer and improved management of the disease by detecting cancer-associated molecular alterations in blood. This Perspective reviews key advances in liquid biopsy-based multi-omics approaches for biomarker discovery and introduces the 'nano-omics' paradigm, which utilizes nanotechnology tools for the analysis of blood-circulating cancerome.

Circulating tumour DNA - looking beyond the blood

Ann Tivey, Matt Church, Dominic Rothwell, Caroline Dive, Natalie Cook

Summary: Over the past decade, liquid biopsy techniques have emerged as alternatives to traditional tissue biopsy samples. Majority of research in this field has focused on blood-based biomarkers, especially circulating tumor DNA (ctDNA) derived from plasma. However, ctDNA can also be obtained from non-blood sources such as urine, cerebrospinal fluid, and pleural or peritoneal fluid. In this review, the authors discuss the advances in analyzing ctDNA from non-blood sources, exploring the distinct advantages and technical aspects of non-blood ctDNA assay development. They also reflect on when non-blood ctDNA can have advantages over plasma ctDNA and the challenges of translating these assays into clinical use.

Is Reflex Germline BRCA1/2 Testing Necessary in Women Diagnosed with Non-Mucinous High-Grade Epithelial Ovarian Cancer Aged 80 Years or Older?

Robert D. D. Morgan, George J. J. Burghel, Nicola Flaum, Michael Bulman, Philip Smith, Andrew R. R. Clamp, Jurjees Hasan, Claire L. L. Mitchell, Zena Salih, Emma R. R. Woodward, Fiona Lalloo, Emma J. J. Crosbie, Richard J. J. Edmondson, Helene Schlecht, Gordon C. C. Jayson, D. Gareth R. Evans

Summary: Approximately 15% of patients diagnosed with high-grade non-mucinous epithelial ovarian cancer (EOC) have a germline BRCA1/2 mutation, with somatic mutations occurring more frequently in patients aged >= 80. Germline BRCA1/2 testing in this age group can be reserved for those with a detectable tumour BRCA1/2 mutation. Testing for tumour BRCA1/2 and homologous recombination deficiency is sufficient for patients aged >= 80 with non-mucinous high-grade EOC.

Hole behavior captured by analysis of instantaneous amplitude and phase of sarcosynced oscillations reveals wave characteristics of sarcomeric oscillations

Seine A. Shintani

Summary: In this study, the researchers used signal analysis to study the instantaneous amplitude and phase of sarcomeric oscillations in skeletal muscle. They identified two types of oscillations, sarcomeric oscillations and sarcosynced oscillations, and visualized their behavior during propagating waves. The researchers discovered the presence of sarcomeric defect holes and sarcomeric collision holes, which are important indicators for understanding the oscillation properties of sarcomeres. This finding has important implications for improving our understanding of muscle function and its regulatory mechanisms.

TP53INP2 modulates the malignant progression of colorectal cancer by reducing the inactive form of β-catenin

Ke Shi, Yunlong Shan, Xiao Sun, Kuida Chen, Qiong Luo, Qiang Xu

Summary: This study found that low expression of TP53INP2 is associated with poor survival in colorectal cancer (CRC) patients. As the malignancy of CRC progresses, TP53INP2 expression gradually decreases. Knockdown of TP53INP2 promotes CRC cell proliferation and tumor growth. Mechanistically, TP53INP2 deficiency decreases phosphorylation of beta-catenin, leading to increased accumulation and enhanced nuclear translocation and transcriptional activity. Additionally, TP53INP2 sequesters TIM50, inhibiting its activation of beta-catenin. In conclusion, downregulation of TP53INP2 promotes CRC progression by activating beta-catenin.

The four subunits of rabbit skeletal muscle lactate dehydrogenase do not exert their catalytic action additively

Martina Rossi, Fabio Tomaselli, Alejandro Hochkoeppler

Summary: Oligomeric enzymes are known for their higher catalytic rates compared to monomeric enzymes, but the extent of additivity in their activity is still not well understood. This study used tetrameric rabbit lactate dehydrogenase as a model to examine the kinetics of its catalytic action. Surprisingly, when the concentration of the limiting reactant exceeded that of a single subunit, there was a significant slowdown in the enzyme's conformational rearrangements.

Summary: The fatty acid elongation enzyme ELOVL5 plays a critical role in promoting metastasis in prostate cancer. Knocking down ELOVL5 leads to the accumulation of malonyl-CoA, which inhibits fatty acid oxidation in mitochondria. This study highlights the importance of fatty acid elongation in regulating cell viability and provides a potential target for prostate cancer treatment.
