Recycled melanoma-secreted melanosomes regulate tumor-associated macrophage diversification.

EMBO J

September 2024

Department of Human Genetics and Biochemistry, Sackler Faculty of Medicine, Tel Aviv University, Tel Aviv, 69978, Israel.

Article Synopsis
  • Extracellular vesicles (EVs), particularly melanosomes secreted by melanocytes, are revealed as key players in intercellular communication, allowing intact transfer of melanin between cells.
  • These melanosomes gain distinct protein signatures within receiving cells and can be further passed to other cells, like macrophages, influencing their polarization towards either pro-tumor or immune cell types.
  • In melanoma, the presence of specific melanosome markers in macrophages correlates with disease aggressiveness and highlights the potential of targeting melanosome interactions to hinder melanoma progression.

Using immunotherapy to fight cancer, and specifically, the use of engineered T-cells expressing a chimeric receptor against an antigen found on malignant cells (chimeric antigen receptor, CAR-T cells) constitutes a significant breakthrough in the treatment of the disease. In recent years, several CAR-T therapies have been approved in Europe and the USA, and some are already approved and funded through the national health basket in Israel, for the indications of diffuse large B-cell lymphoma, mantle cell lymphoma and B-cell acute lymphoblastic leukemia, after the failure of at least two lines of treatment. The treatment with CAR-T cells achieves prolonged remissions and even long-term cure of patients who had a very poor prognosis.

Article Synopsis
  • - Chimeric antigen receptor T cells targeting CD19 (CART-19) have been effective in treating relapsed/refractory B-Cell precursor acute lymphoblastic leukemia (BCP-ALL), with most patients achieving complete remission after treatment.
  • - A study analyzed 39 young patients who received the anti-CD22 drug inotuzumab ozogamicin (InO) either before or after T-cell apheresis, finding no significant differences in treatment outcomes based on the timing of InO administration.
  • - Overall survival rates and event-free survival rates after CART-19 infusion were comparable for patients with and without prior InO exposure, suggesting prior use of InO does not negatively impact the effectiveness of CART

Duplications disrupt chromatin architecture and rewire GPR101-enhancer communication in X-linked acrogigantism.

Am J Hum Genet

April 2022

Laboratory of Cellular and Molecular Endocrinology and Laboratory of Pharmacology and Brain Pathology, Humanitas Research Hospital - IRCCS, 20089 Rozzano (Mi), Italy. Electronic address:

X-linked acrogigantism (X-LAG) is the most severe form of pituitary gigantism and is characterized by aggressive growth hormone (GH)-secreting pituitary tumors that occur in early childhood. X-LAG is associated with chromosome Xq26.3 duplications (the X-LAG locus typically includes VGLL1, CD40LG, ARHGEF6, RBMX, and GPR101) that lead to massive pituitary tumoral expression of GPR101, a novel regulator of GH secretion.

Guideline-directed medical therapy (GDMT) has the potential to reduce the risks of mortality and hospitalisation in patients with heart failure (HF) with reduced ejection fraction (HFrEF). However, real-world data indicate that many patients with HFrEF do not receive optimised GDMT, which involves several different medications, many of which require up-titration to target doses. There are many challenges to implementing GDMT, the most important being patient-related factors (comorbidities, advanced age, frailty, cognitive impairment, poor adherence, low socioeconomic status), treatment-related factors (intolerance, side-effects) and healthcare-related factors that influence availability and accessibility of HF care.

Parkinson Disease-Modification Encompassing Rotenone and 6-Hydroxydopamine Neurotoxicity by the Microtubule-Protecting Drug Candidate SKIP.

J Mol Neurosci

August 2021

Elton Laboratory for Molecular Neuroendocrinology, Department of Human Molecular Genetics and Biochemistry, Sackler Faculty of Medicine, Adams Super Center for Brain Studies and Sagol School of Neuroscience, Tel Aviv University, 69978, Tel Aviv, Israel.

Encompassing live cell imaging and morphometrics at the microscopical level, we showed here, for the first time, protection of neuronal-like cells by the novel drug candidate, SKIP, against the Parkinson's disease-related neurotoxin, rotenone. Mechanistically, rotenone disrupted microtubule dynamics, which SKIP partially repaired through microtubule end-binding proteins, coupled with increasing neurite branch length. Given the previous association of rotenone toxicity with increased dopaminergic cell death hallmarking Parkinson's disease, we chose an established rat model of 6-hydroxydopamine (6-OHDA) toxicity to initially evaluate SKIP in vivo.

The X-linked acrogigantism-associated gene gpr101 is a regulator of early embryonic development and growth in zebrafish.

Mol Cell Endocrinol

January 2021

Section on Endocrinology and Genetics, Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD), National Institutes of Health (NIH), Bethesda, MD, USA.

We recently described X-linked acrogigantism (X-LAG), a condition of early childhood-onset pituitary gigantism associated with microduplications of the GPR101 receptor. The expression of GPR101 in hyperplastic pituitary regions and tumors in X-LAG patients, and GPR101's normally transient pituitary expression during fetal development, suggest a role in the regulation of growth. Nevertheless, little is still known about GPR101's physiological functions, especially during development.

Background: Peritoneal dialysis (PD) is increasingly used for the long-term management of hypervolemic refractory congestive heart failure (CHF) patients, in particular when complicated by renal insufficiency. While PD has many advantages over hemodialysis (HD) in those patients, there is a controversy concerning survival superiority of PD compared with HD in this population. The aim of the study was to define typical patient profile and to compare outcomes of patients with CHF and renal failure treated with HD or PD.
