Juno cancer study halted after patient deaths, shares slide 30 pct

(Reuters) - A Juno Therapeutics Inc trial of its experimental cancer therapy, known as JCAR015, was put on hold by U.S. regulators after the deaths last week of two leukemia patients, the company said on Thursday.

Specifically, HMGB1 release has been shown to occur with a specific form of induced cell death known as necroptosis. In the present study, we examined the role of HMGB1 in...

Unfortunately these intensive chemotherapeutic regimes, often show disappointing results due to the development of drug resistance and higher nonspecific toxicity on normal tissues. In cancer treatment, it is critically important to minimize toxicity while preserving efficacy. We have previously addressed this issue and proposed a nanoparticle-based combination therapy involving b...

Design, synthesis and biological evaluation of novel α-acyloxy carboxamides via Passerini reaction as caspase 3/7 activators. Eur J Med Chem. 2019 Feb 22;168:340-356 Authors: Salah Ayoup M, Wahby Y, Abdel-Hamid H, Ramadan ES, Teleb M, Abu-Serie MM, Noby A Abstract Evasion of apoptosis is a hallmark of cancer. Caspases; the key executors of apoptotic cascade are attractive targets for selective induction of apoptosis in cancer cells. Within this approach, various caspase activators were introduced as lead anticancer agents. In the current study, a new series of multifunctional Passerini products ...

For years, cancer treatment was dominated by chemotherapy, radiation therapy, and stem cell transplantation. New insights into genetic characteristics of leukemic cells have initiated the development of the chimeric antigen receptor (CAR) T-cell therapy. This type of adoptive cell immunotherapy has been a breakthrough in the treatment of aggressive B-cell lymphoma and B-cell precursor acute lymphoblastic leukemia. In August 2018, the European Commission has approved the first CAR T-cell products – tisagenlecleucel (Kymriah®, Novartis) and axicabtagene ciloleucel (Yescarta®, Gilead) – for hematological n...

to AP Abstract Cancer stem cells show epigenetic plasticity and intrinsic resistance to anti-cancer therapy, rendering capable of initiating cancer relapse and progression. Transcription factor OCT-4 regulates various pathways in stem cells, but its expression can be regulated by pseudogenes. This work evaluated how OCT4-PG1 pseudogene can affect OCT-4 expression and mechanisms related to the multidrug resistance (MDR) phenotype in FEPS cells. Considering that OCT-4 protein is a transcription factor that regulates expression of ABC transporters, level of gene expression, activity of ABC proteins and cell sensitivi...

Abstract Development of targeted cancer therapy requires a thorough understanding of mechanisms of tumorigenesis as well as mechanisms of action of therapeutics. This is challenging because by the time patients are diagnosed with cancer, early events of tumorigenesis have already taken place. Similarly, development of cancer immunotherapies is hampered by a lack of appropriate small animal models with autologous human tumor and immune system. In this article, we report the development of a mouse model of human acute myeloid leukemia (AML) with autologous immune system for studying early events of human leukemogene...

Therapy-related myelodysplastic syndrome and acute myeloid leukemia (t-MDS/AML) are rare but well-recognized complications of cancer therapy. Allogeneic hematopoietic cell transplantation (HCT) with myeloablative conditioning (MAC) remains the mainstay of treatment but is associated with a high incidence of non-relapse mortality (NRM). Reduced intensity conditioning (RIC) may reduce NRM in these heavily pre-treated patients. The primary objective of this study was to compare outcomes following RIC and MAC regimens in patients receiving an allogeneic HCT.

CART therapy is revolutionizing modern cancer therapy, with two anti-CD19 CARTs FDA-approved for relapsed/refractory B cell lymphoma/leukemia and many other CARTs for solid and liquid tumors currently undergoing clinical trials. However, in current clinical practice, suboptimal CART persistence and tumor killing permit tumor cell escape and, ultimately, disease relapse. Reasoning that a pro-lymphoid growth factor could promote CART efficacy, we supplemented UCART infusion with subcutaneous injections of the long-acting form of recombinant human interleukin-7 fused with hybrid Fc (rhIL-7-hyFc, NT-I7) in vivo using a CD19+ l...

In this study, we show that calorie restriction is protective against age-related increases in senescence and microglia activation and pro-inflammatory cytokine expression in an animal model of aging. Further, these protective effects mitigated age-related decline in neuroblast and neuronal production, and enhanced olfactory memory performance, a behavioral index of neurogenesis in the SVZ. Our results support the concept that calorie restriction might be an effective anti-aging intervention in the context of healthy brain aging. Greater Modest Activity in Late Life Correlates with Lower Incidence of Dementia ...

Abstract Arsenic trioxide (ATO) is among the first-line chemotherapeutic drugs used in oncological practice. It has shown substantial efficacy in treating patients with relapsed or refractory acute promyelocytic leukaemia. The clinical use of ATO is hampered due to cardiotoxicity and hence many patients are precluded from receiving this highly effective treatment. An alternative to this would be to use any drug that can ameliorate the cardiotoxic effects and allow exploiting the full therapeutic potential of ATO, with considerable impact on cancer therapy. Generation of reactive oxygen species is involved in ...
