Haematologica

January 2025

Division of Oncology, the Children's Hospital of Philadelphia, Philadelphia, PA, USA; Department of Pediatrics, the University of Pennsylvania Perelman School of Medicine, Philadelphia, PA.

While outcomes for pediatric acute lymphoblastic leukemia (ALL) and lymphoblastic lymphoma (LBL) have improved dramatically in recent decades, relapsed and refractory disease remain a significant therapeutic challenge. This is particularly true for patients with T-cell ALL and LBL, where survival for patients with relapsed/refractory disease remains dismal. Recent efforts to comprehensively profile the genomics of T-ALL/LBL to improve understanding of disease biology have enhanced our ability to identify high-risk patients at diagnosis who are more likely to relapse and have also identified novel targets for precision medicines.

The prognosis of pediatric acute myeloid leukemia (AML) remains poor compared with pediatric acute lymphoblastic leukemia (ALL); accurate diagnosis and treatment strategies based on the genomic background are strongly needed. Recent advances in sequencing technologies have identified novel pediatric AML subtypes, including BCL11B structural variants and UBTF tandem duplications (UBTF-TD), associated with poor prognosis. In contrast, these novel subtypes do not fit into the diagnostic systems for AML of the 5th edition WHO classification or International Consensus Classifications (ICC) released in 2022.

Poplar transformation with variable explant sources to maximize transformation efficiency.

Sci Rep

January 2025

Biosciences Division, Oak Ridge National Laboratory, Oak Ridge, TN, USA.

For decades, Agrobacterium tumefaciens-mediated plant transformation has played an integral role in advancing fundamental and applied plant biology. The recent omnipresent emergence of synthetic biology, which relies on plant transformation to manipulate plant DNA and gene expression for novel product biosynthesis, has further propelled basic as well as applied interests in plant transformation technologies. The strong demand for a faster design-build-test-learn cycle, the essence of synthetic biology, is, however, still ill-matched with the long-standing issues of high tissue culture recalcitrance and low transformation efficiency of a wide range of plant species especially food, fiber and energy crops.

Selpercatinib mitigates cancer cachexia independent of anti-tumor activity in the HT1080 tumor model.

Cancer Lett

January 2025

Peggy and Charles Stephenson Cancer Center, University of Oklahoma Health Sciences Center, Oklahoma City, OK, USA; Department of Pathology, University of Oklahoma Health Sciences Center, Oklahoma City, OK, USA. Electronic address:

Anorexia is a major cause of cancer cachexia and is induced by growth differentiation factor-15 (GDF15), which activates the rearranged during transfection (RET) protein tyrosine kinase in the hindbrain through GDF family receptor α-like (GFRAL), raising the possibility of targeting RET for cancer cachexia treatment. RET-altered cancer patients treated with RET-selective kinase inhibitors gain weight, however, it is unclear whether this results from tumor regression that improves the overall health of patients. Thus, the potential of using a RET inhibitor to address cancer cachexia remains unknown.
