The advent of chimeric antigen receptor (CAR)-T cell immunotherapies has led to breakthroughs in the treatment of hematological malignancies. However, their success in treating solid tumors has been limited. CAR-natural killer (NK) cells have several advantages over CAR-T cells because NK cells can be made from pre-existing cell lines or allogeneic NK cells with a mismatched major histocompatibility complex (MHC), which means they are more likely to become an "off-the-shelf" product. Moreover, they can kill cancer cells via CAR-dependent/independent pathways and have limited toxicity. Macrophages are the most malleable immune cells in the body. These cells can efficiently infiltrate into tumors and are present in large numbers in tumor microenvironments (TMEs). Importantly, CAR-macrophages (CAR-Ms) have recently yielded exciting preclinical results in several solid tumors. Nevertheless, CAR-T, CAR-NK, and CAR-M all have their own advantages and limitations. In this review, we systematically discuss the current status, progress, and the major hurdles of CAR-T cells, CAR-NK cells, and CAR-M as they relate to five aspects: CAR structure, therapeutic mechanisms, the latest research progress, current challenges and solutions, and comparison according to the existing research in order to provide a reasonable option for treating solid tumors in the future.

Semi-dwarfing improves the lodging resistance and yield of rice,and the vast majority of modern rice varieties harbor the sd1 allele to decrease plant height,resulting in reduced genetic diversity and negative agronomic traits.Thus,exploring alternative sources of dwarfism is imperative for rice breeding.Here,we identified a novel RGA1 allele,d1-w,from a local indica variety Xiaolixiang(XLX)using a map-based cloning approach.Compared with other rice varieties,RGA1 in XLX contained a unique single nucleotide polymorphism that resulted in an additional transcript and reduced functional RGA1 transcript level.The RGA1 from Nipponbare was introduced into XLX to estimate the value of d1-w in rice breeding.Compared with transgenic XLX plants(XLX^(D1)),XLX exhibited reduced plant height,increased stem strength,lower reactive oxygen species accumulation,delayed senescence,stronger photosynthesis,higher grain yield and quality(including external,milling and nutritional qualities),and enhanced resistance to drought and Rhizoctonia solani.Therefore,we proposed that the d1-w allele has potential as an excellent dwarfism resource for rice breeding.

Previously,we reported that a cell population derived from human fetal bone marrow(BM),termed here Flk1+CD34−postembryonic pluripotent stem cells(PPSCs)that have the characteristics of mesenchymal stem cells(MSCs),could differentiate into ectodermal,endodermal and mesodermal cell types at the single cell level in vitro,and that these cells could also differentiate into the epithelium of liver,lung,gut,as well as the hematopoietic and endothelial lineages after transplantion into irradiated non-obese diabetic/severe combined immunodeficient(NOD/SCID)mice.In this study,we further isolated pluripotent stem cells from human fetal heart,liver,muscle,lung,derma,kidney,and fat and then analyzed the characteristics and function of these stem cells.It was found that the phenotype of the culture-expanded pluripotent stem cells from different fetal tissues was similar to BM-derived Flk1^(+)CD34^(−)PPSCs,i.e.Flk1 and CD44 positive,GlyA,CD34,CD45,class I-HLA and HLA-DR negative.Morphologically,these cells were fibroblast-like and the doubling time was about 30 h.More importantly,culture-expanded pluripotent stem cells from all these fetal tissues were able to differentiate into cells with morphologic and phenotypic characteristics of adipocytes,osteocytes,neurons,glial cells and hepatocytes.These pluripotent stem cells with characteristics similar to fetal BM-derived Flk1^(+)CD34^(−)PPSCs can be selected and cultured from tissues other than the BM.This phenomenon may help explain the“stem cell plasticity”found in multiple human tissues.In addition,as fetal BM-derived Flk1^(+)CD34^(−)PPSCs,these pluripotent stem cells from different fetal tissues had the capacity for self-renewal and multi-lineage differentiation even after being expanded for more than 40 population doublings in vitro.Thus,they may be an ideal source of stem cells for treatment of inherited or degenerative diseases.

Ferroptosis is an iron-dependent cell death pathway that is different from apoptosis,pyroptosis,and necrosis.The main characteristics of ferroptosis are the Fenton reaction mediated by intracellular free divalent iron ions,lipid peroxidation of cell membrane lipids,and inhibition of the anti-lipid peroxidation activity of intracellular glutathione peroxidase 4(GPX4).Recent studies have shown that ferroptosis can be involved in the pathological processes of many disorders,such as ischemia-reperfusion injury,nervous system diseases,and blood diseases.However,the specific mechanisms by which ferroptosis participates in the occurrence and development of acute leukemia still need to be more fully and deeply studied.This article reviews the characteristics of ferroptosis and the regulatory mechanisms promoting or inhibiting ferroptosis.More importantly,it further discusses the role of ferroptosis in acute leukemia and predicts a change in treatment strategy brought about by increased knowledge of the role of ferroptosis in acute leukemia.

Electrolytic water splitting by renewable energy is a technology with great potential for producing hydrogen(H_(2))without carbon emission,but this technical route is hindered by its huge energy(electricity)cost,which is mainly wasted by the anode oxygen evolution reaction(OER)while the value of the anode product(oxygen)is very limited.Replacing the high-energy-cost OER with a selective organic compound electrooxidation carried out at a relatively lower potential can reduce the electricity cost while producing value-added chemicals.Currently,H_(2) generation coupled with synthesis of value-added organic compounds faces the challenge of low selectivity and slow generation rate of the anodic products.One-dimensional(1D)nanocatalysts with a unique morphology,well-defined active sites,and good electron conductivity have shown excellent performance in many electrocatalytic reactions.The rational design and regulation of 1D nanocatalysts through surface engineering can optimize the adsorption energy of intermediate molecules and improve the selectivity of organic electrooxidation reactions.Herein,we summarized the recent research progress of 1D nanocatalysts applied in different organic electrooxidation reactions and introduced several different fabrication strategies for surface engineering of 1D nanocatalysts.Then,we focused on the relationship between surface engineering and the selectivity of organic electrooxidation reaction products.Finally,future challenges and development prospects of 1D nanocatalysts in the coupled system consisting of organic electrooxidation and hydrogen evolution reactions are briefly outlined.

Senescence is the last developmental process in plant,which has an important impact on crop yield and quality.In this study,a stable hereditary early-senescence line BC64 was isolated from the high-generation recombinant inbred lines of 93-11 and Wuyunjing7(W7).Genetic analysis showed that the premature aging phenotype was controlled by a dominant gene derived from 93-11.By linkage analysis,the gene was primarily mapped in the region between marker B4 and B5 near the centromere of chromosome 4,described as ES(4).Through multiple backcrossing with W7,the near-isogenic line of ES(4)(NIL-ES(4))was obtained.Compared with wild-type W7,NIL-ES(4)plants showed more sever senescence phenotype in both nature and dark conditions.In NIL plants,leaves turned yellow at the fully tillering stage;photosynthetic rate,pollen fertility and seed setting rate were decreased.Moreover,the malondialdehyde,proline content and relative conductivity in NIL-ES(4)were significantly higher than those in W7;both transcript level and activities of reactive oxygen species scavenging enzymes were repressed;H2O2 and O^(2−)were significantly accumulated.This study provides a basis for further cloning and function identification of ES(4).

The tyrosine kinase inhibitors （TKI） of the epidermal growth factor receptor （EGFR） are becoming the first line of therapy for advanced non-small cell lung cancer （NSCLC）. Acquired mutations in EGFR account for one of the major mechanisms of resistance to the TKIs. Three generations of EGFR TKIs have been used in clinical applications. AZD9291 （osimertinib; Tagrisso） is the first and only FDA approved third-generation EGFR TKI for T790M-positive advanced NSCLC patients. However, resistance to AZD9291 arises after 9-13 months of therapy. The mechanisms of resistance to third-generation inhibitors reported to date include the EGFR C797S mutation, EGFR L718Q mutation, and amplifications of HER-2, MET, or ERBB2. To overcome the acquired resistance to AZD9291, EAI045 was discovered and recently reported to be an allosteric EGFR inhibitor that overcomes T790M- and C797S-mediated resistance. This review summarizes recent investigations on the mechanisms of resistance to the EGFR TKIs, as well as the latest development of EAI045 as a fourth-generation EGFR inhibitor.

Conventional combination therapies have not resulted in considerable progress in the treatment of acute myeloid leukemia (AML). Elderly patients with AML and poor risk factors have grave prognosis. Midostaurin has been recently approved for the treatment of FLT-3-mutated AML. Venetoclax, a BCL-2 inhibitor, has been approved for the treatment of relapsed and/or refractory chronic lymphoid leukemia. Clinical trials on applying venetoclax in combination with cytarabine and other agents to treat various hematological malignancies are currently underway. Here, we present a case of a male patient with poor performance status and who developed AML following allogeneic hematopoietic stem cell transplant for high-risk myelodysplasia. The patient with high risk AML achieved complete response to the combined treatment regimen of low-dose cytarabine and venetoclax. Furthermore, we reviewed current clinical trials on the use of venetoclax for hematological malignancies.
