Isolation, structural characteristics and cytotoxicity of the constitutes from L.

Seventeen compounds were isolated from the aerial parts of L., including 1 previously undescribed xanthone and 6 firstly isolated compounds. The structures of compounds were identified by Mass spectrometry and NMR spectroscopy.

The evolving tumor-associated adipose tissue microenvironment in breast cancer: from cancer initiation to metastatic outgrowth.

Adipocytes represent a significant proportion of breast tissue, comprising between 3.7 and 37% of stromal tissue. They play a pivotal role in metabolic regulation, energy supply, metabolic regulation, support effects, and cytokine release within the breast.

Biallelic variants in the cause mitochondrial respiratory complex assembly defects associated with Leigh syndrome in probands.

Background: Variants in have been reported to be associated with Leigh syndrome. However, further expansion of the -phenotype and variants spectrum of -related Leigh syndrome are still required.

Methods: Two patients diagnosed with Leigh syndrome were recruited, and whole-exome sequencing was performed to identify the genetic variants responsible for the abnormal gait, dystonia, and bilateral basal ganglia lesions, followed by validation using Sanger sequencing.

Expanding the phenotypic and genetic spectrum of GTPBP3 deficiency: findings from nine Chinese pedigrees.

Background: GTPBP3 catalyzes τm(s) U biosynthesis at the 34th wobble position of mitochondrial tRNAs, the hypomodification of τmU leads to mitochondrial disease. While twenty-three variants of GTPBP3 have been reported worldwide, the genetic landscape in China remains uncertain.

Methods: By using whole-exome sequencing, the candidate individuals carrying GTPBP3 variants were screened and identified.
