MDA-9/Syntenin as a therapeutic cancer metastasis target: current molecular and preclinical understanding.

Introduction: Metastasis is a principal cause of patient morbidity and death from solid cancers with current therapies being inadequate.

Areas Covered: Detailed genomic analyses document mutational differences between the initial tumor and metastatic clones, posing a challenge to current targeted therapies, which focus predominantly on the phenotype of primary tumors. Considering the diverse signaling cascades and numerous compensatory pathways in metastasis, designing broad-spectrum anti-metastatic therapies remains challenging.

Allogeneic CAR T Cell Products Cemacabtagene Ansegedleucel/ALLO-501 in Relapsed/Refractory Large B-Cell Lymphoma: Phase 1 Experience From the ALPHA2/ALPHA Clinical Studies.

Purpose: Off-the-shelf, allogeneic CD19 chimeric antigen receptor (CAR) T cell products may improve access to treatment versus autologous ones. We report the phase 1 experience of the allogeneic CD19 CAR T-cell product cemacabtagene ansegedleucel (cema-cel) and its predecessor, ALLO-501, in CD19 CAR T-naive patients with relapsed/refractory large B-cell lymphoma (R/R LBCL).

Patients And Methods: In the ALPHA2/ALPHA studies, safety and efficacy of allogeneic CD19 CAR T cells were evaluated in CD19 CAR T treatment-naive patients with R/R LBCL.

Associations between common genetic variants and income provide insights about the socio-economic health gradient.

We conducted a genome-wide association study on income among individuals of European descent (N = 668,288) to investigate the relationship between socio-economic status and health disparities. We identified 162 genomic loci associated with a common genetic factor underlying various income measures, all with small effect sizes (the Income Factor). Our polygenic index captures 1-5% of income variance, with only one fourth due to direct genetic effects.

Taking a step back: Parents' experiences of the decision-making process for elective orthognathic surgery in cleft lip and palate (IPA).

Objective: This study explored parents' experiences of the transition of responsibility to their child for healthcare decisions relating to their cleft lip and/or palate (CL/P).

Methods: Online semi-structured interviews were conducted with 11 participants (six females and five males, aged 41 to 60 years). They were parents of young people who had decided whether to undergo orthognathic surgery.

T helper 2 cell-directed immunotherapy eliminates precancerous skin lesions.

The continuous rise in skin cancer incidence highlights an imperative for improved skin cancer prevention. Topical calcipotriol-plus-5-fluorouracil (calcipotriol-plus-5-FU) immunotherapy effectively eliminates precancerous skin lesions and prevents squamous cell carcinoma (SCC) in patients. However, its mechanism of action remains unclear.

A blood-based mRNA signature distinguishes people with Long COVID from recovered individuals.

Introduction: Long COVID is a debilitating condition that lasts for more than three months post-infection by SARS-CoV-2. On average, one in ten individuals infected with SARS CoV- 2 develops Long COVID worldwide. A knowledge gap exists in our understanding of the mechanisms, genetic risk factors, and biomarkers that could be associated with Long COVID.

Global analysis of endogenous protein disorder in cells.

Disorder and flexibility in protein structures are essential for biological function but can also contribute to diseases, such as neurodegenerative disorders. However, characterizing protein folding on a proteome-wide scale within biological matrices remains challenging. Here we present a method using a bifunctional chemical probe, named TME, to capture in situ, enrich and quantify endogenous protein disorder in cells.

Intravenous and intracranial GD2-CAR T cells for H3K27M diffuse midline gliomas.

H3K27M-mutant diffuse midline gliomas (DMGs) express high levels of the disialoganglioside GD2 (ref. ). Chimeric antigen receptor-modified T cells targeting GD2 (GD2-CART) eradicated DMGs in preclinical models.

Design and Synthesis of Small Molecule Probes of MDA-9/Syntenin.

MDA-9/Syntenin, a key scaffolding protein and a molecular hub involved in a diverse range of cell signaling responses, has proved to be a challenging target for the design and discovery of small molecule probes. In this paper, we report on the design and synthesis of small molecule ligands of this key protein. Genetic algorithm-based computational design and the five-eight step synthesis of three molecules led to ligands with affinities in the range of 1-3 µM, a 20-60-fold improvement over literature reports.

Comments and Controversies in Oncology: The Tribulations of Trials Developing ONC201.

Our international team highlights issues with efficacy reports in several studies on DMG with the new drug ONC201.

The Multifaceted Interactions of Atg1 with Mitochondrial Function, Endocytosis, Growth, and Development.

Autophagy is a degradative recycling process central to the maintenance of homeostasis in all eukaryotes. By ensuring the degradation of damaged mitochondria, it plays a key role in maintaining mitochondrial health and function. Of the highly conserved autophagy proteins, autophagy-related protein 1 (Atg1) is essential to the process.

Molecular landscape of prostate cancer bone metastasis.

Prostate cancer (PC) has a high propensity to develop bone metastases, causing severe pain and pathological fractures that profoundly impact a patients' normal functions. Current clinical intervention is mainly palliative focused on pain management, and tumor progression is refractory to standard therapeutic regimens. This limited treatment efficacy is at least partially due to a lack of comprehensive understanding of the molecular landscape of the disease pathology, along with the intensive overlapping of physiological and pathological molecular signaling.

Sequential intravenous and intracerebroventricular GD2-CAR T-cell therapy for H3K27M-mutated diffuse midline gliomas.

H3K27M-mutant diffuse midline gliomas (DMGs) express high levels of the GD2 disialoganglioside and chimeric antigen receptor modified T-cells targeting GD2 (GD2-CART) eradicate DMGs in preclinical models. Arm A of the Phase I trial NCT04196413 administered one IV dose of autologous GD2-CART to patients with H3K27M-mutant pontine (DIPG) or spinal (sDMG) diffuse midline glioma at two dose levels (DL1=1e6/kg; DL2=3e6/kg) following lymphodepleting (LD) chemotherapy. Patients with clinical or imaging benefit were eligible for subsequent intracerebroventricular (ICV) GD2-CART infusions (10-30e6 GD2-CART).

Oxygen consumption rate of flatworms under the influence of wake- and sleep-promoting neurotransmitters.

Flatworms are among the best studied animal models for regeneration; however, they also represent an emerging opportunity to investigate other biological processes as well. For instance, flatworms are nocturnal and sleep during the day, a state that is regulated by sleep/wake history and the action of the sleep-promoting neurotransmitter gamma-aminobutyric acid (or GABA). Sleep is widespread across the animal kingdom, where it serves many nonexclusive functions.

Noninvasive therapy of brain cancer using a unique systemic delivery methodology with a cancer terminator virus.

Primary, glioblastoma, and secondary brain tumors, from metastases outside the brain, are among the most aggressive and therapeutically resistant cancers. A physiological barrier protecting the brain, the blood-brain barrier (BBB), functions as a deterrent to effective therapies. To enhance cancer therapy, we developed a cancer terminator virus (CTV), a unique tropism-modified adenovirus consisting of serotype 3 fiber knob on an otherwise Ad5 capsid that replicates in a cancer-selective manner and simultaneously produces a potent therapeutic cytokine, melanoma differentiation-associated gene-7/interleukin-24 (MDA-7/IL-24).

Loss of function of FAM177A1, a Golgi complex localized protein, causes a novel neurodevelopmental disorder.

Purpose: The function of FAM177A1 and its relationship to human disease is largely unknown. Recent studies have demonstrated FAM177A1 to be a critical immune-associated gene. One previous case study has linked FAM177A1 to a neurodevelopmental disorder in 4 siblings.

Polycystin-2 Mediated Calcium Signalling in the Model for Autosomal Dominant Polycystic Kidney Disease.

Autosomal dominant polycystic kidney disease (ADPKD) occurs when the proteins Polycystin-1 (PC1, ) and Polycystin-2 (PC2, ) contain mutations. PC1 is a large membrane receptor that can interact and form a complex with the calcium-permeable cation channel PC2. This complex localizes to the plasma membrane, primary cilia and ER.
