Benzyl and phenethyl isothiocyanates as promising epigenetic drug compounds by modulating histone acetylation and methylation marks in malignant melanoma.

Invest New Drugs 2021 May 8. Epub 2021 May 8.

Department of Applied Sciences, Northumbria University, Newcastle Upon Tyne, UK.

Melanoma is an aggressive skin cancer with increasing incidence rates globally. On the other hand, isothiocyanates are derived from cruciferous vegetables and are known to exert a wide range of anti-cancer activities including, among others, their ability to interact with the epigenome in order to supress cancer progression. The aim of this study was to determine the role of phenethyl and benzyl isothiocyanates in modulating histone acetylation and methylation as a potential epigenetic therapeutic strategy in an in vitro model of malignant melanoma.

Predicting anti-PD-1 responders in malignant melanoma from the frequency of S100A9+ monocytes in the blood.

J Immunother Cancer 2021 May;9(5)

Department of Medicine, Centre for Molecular Medicine, Karolinska Institutet, Stockholm, Stockholm, Sweden

Background: While programmed cell death receptor 1 (PD-1) blockade treatment has revolutionized treatment of patients with melanoma, clinical outcomes are highly variable, and only a fraction of patients show durable responses. Therefore, there is a clear need for predictive biomarkers to select patients who will benefit from the treatment.

Method: To identify potential predictive markers for response to PD-1 checkpoint blockade immunotherapy, we conducted single-cell RNA sequencing analyses of peripheral blood mononuclear cells (PBMC) (n=8), as well as an in-depth immune monitoring study (n=20) by flow cytometry in patients with advanced melanoma undergoing treatment with nivolumab at Karolinska University Hospital.

Checkpoint inhibition in combination with an immunoboost of external beam radiotherapy in solid tumors (CHEERS): study protocol for a phase 2, open-label, randomized controlled trial.

BMC Cancer 2021 May 7;21(1):514. Epub 2021 May 7.

Cancer Research Institute Ghent (CRIG), Ghent University, Ghent, Belgium.

Background: While the introduction of checkpoint inhibitors (CPIs) as standard of care treatment for various tumor types has led to considerable improvements in clinical outcome, the majority of patients still fail to respond. Preclinical data suggest that stereotactic body radiotherapy (SBRT) could work synergistically with CPIs by acting as an in situ cancer vaccine, thus potentially increasing response rates and prolonging disease control. Though SBRT administered concurrently with CPIs has been shown to be safe, evidence of its efficacy from large randomized trials is still lacking. Read More

Bioelectrical approaches to cancer as a problem of the scaling of the cellular self.

Michael Levin

Prog Biophys Mol Biol 2021 May 4. Epub 2021 May 4.

Allen Discovery Center at Tufts University, 200 Boston Ave., Suite 4600, Medford, MA, 02155, USA. Electronic address:

One lens with which to understand the complex phenomenon of cancer is that of developmental biology. Cancer is the inevitable consequence of a breakdown of the communication that enables individual cells to join into computational networks that work towards large-scale, morphogenetic goals instead of more primitive, unicellular objectives. This perspective suggests that cancer may be a physiological disorder, not necessarily due to problems with the genetically-specified protein hardware. Read More

Detection of cancer metastasis: past, present and future.

Clin Exp Metastasis 2021 May 7. Epub 2021 May 7.

Moffitt Cancer Center, Department of Pathology, 12902 Magnolia Drive, Tampa, FL, 33612, USA.

The clinical importance of metastatic spread of cancer has been recognized for centuries, and melanoma has loomed large in historical descriptions of metastases, as well as the numerous mechanistic theories espoused. The "fatal black tumor" described by Hippocrates in 5000 BC that was later termed "melanose" by Rene Laennec in 1804 was recognized to have the propensity to metastasize by William Norris in 1820. And while the prognosis of melanoma was uniformly acknowledged to be dire, Samuel Cooper described surgical removal as having the potential to improve prognosis. Read More

Current management of melanoma patients with nodal metastases.

Clin Exp Metastasis 2021 May 7. Epub 2021 May 7.

Department of Surgery, Morsani School of Medicine, University of South Florida, Tampa, FL, USA.

The management of melanoma patients with nodal metastases has undergone dramatic changes over the last decade. In the past, the standard of care for patients with a positive sentinel lymph node biopsy (SLNB) was a completion lymph node dissection (CLND), while patients with palpable macroscopic nodal disease underwent a therapeutic lymphadenectomy in cases with no evidence of systemic spread. However, studies have shown that SLN metastases present as a spectrum of disease, with certain SLN-based factors being prognostic of and correlated with outcomes. Read More

Genetics of non-syndromic and syndromic oculocutaneous albinism in human and mouse.

Pigment Cell Melanoma Res 2021 May 7. Epub 2021 May 7.

Department of Molecular and Cellular Biology, National Centre for Biotechnology (CNB-CSIC) Madrid, Spain and CIBERER-ISCIII, Darwin 3, 28049, Madrid, Spain.

Oculocutaneous albinism (OCA) is the most frequent presentation of albinism, a heterogeneous rare genetic condition generally associated with variable alterations in pigmentation and with a profound visual impairment. There are non-syndromic and syndromic types of OCA, depending whether the gene product affected impairs essentially the function of melanosomes or, in addition, that of other lysosome related organelles (LROs), respectively. Syndromic OCA can be more severe and associated with additional systemic consequences, beyond pigmentation and vision alterations. Read More
