In recent years, studies have found that mitochondrial transfer between leukemic cells and different types of cells in their bone marrow microenvironment, especially mesenchymal stem cells, plays a key role in the occurrence, development and drug resistance of hematological malignant tumors. This paper mainly introduces the role and latest research progress of mitochondrial transfer in acute and chronic myeloid leukemia, acute lymphoblastic leukemia and multiple myeloma, and briefly describes the mechanism of drug resistance caused by mitochondrial transfer in leukemic cells during chemotherapy. The aim is to provide a new idea and theoretical basis for using intercellular mitochondrial transfer as a potential therapeutic target.

Background: A 73-year-old female with a 3 year history of Alzheimer's disease was treated within the protocol of The Alzheimer's Autism and Cognitive Impairment Stem Cell Treatment Study (ACIST), an IRB approved clinical study registered with clinicaltrials.gov NCT03724136.
Method: The procedure consists of bone marrow aspiration, cell separation using an FDA cleared class 2 device, and intravenous and intranasal administration of the stem cell fraction.

Renal cell carcinoma (RCC) is considered as a "metabolic disease" due to various perturbations in metabolic pathways that could drive cancer development. Glycine decarboxylase (GLDC) is a mitochondrial enzyme that takes part in the oxidation of glycine to support nucleotide biosynthesis via transfer of one-carbon units. Herein, we aimed to investigate the potential role of GLDC in RCC development.

The objective of the present study was to investigate the role and mechanism of bone marrow microenvironmental cells in regulating the mitochondrial mass of leukemia cells, and to uncover the mechanism of leukemia progression at the metabolic level. A mouse model of acute myeloid leukemia (AML) induced by the overexpression of the MLL-AF9 (MA9) fusion protein was established, and the bone marrow cells of AML mice were transplanted into mitochondrial fluorescence reporter mice expressing the Dendra2 protein (mito-Dendra2 mice). The proportion of Dendra2 cells in bone marrow leukemia cells at different stages of AML was quantified by flow cytometry.

Objective: To assess the feasibility of first polar body transfer (PB1T) combined with preimplantation mitochondrial genetic testing for blocking the transmission of a pathogenic mitochondrial DNA 8993T>G mutation.
Methods: A Chinese family affected with Leigh syndrome which had attended the Reproductive Medicine Centre of the First Affiliated Hospital of Anhui Medical University in September 2021 was selected as the study subject. Controlled ovarian hyperstimulation was carried out for the proband after completing the detection of the mitochondrial DNA 8993T>G mutation load among the pedigree members.

Rourke 2002 is an evergreen herbaceous flower with high ornamental value. In this study, we sequenced the complete chloroplast (cp) genome of and reported it for the first time. The cp genome was 158,914 base pairs (bp) in total length, including two inverted repeats (IRs, 27,052 bp), separated by a large single-copy region (LSC, 86,519 bp) and a small single-copy region (SSC, 18,291 bp).
