AI Article Synopsis

  • The PI3K pathway plays a crucial role in managing vital cell functions such as survival, growth, and metabolism, making it essential for overall cellular communication.
  • Due to frequent mutations in the PI3Kalpha isoform linked to cancer, it has become a significant target for drug development in treating solid tumors.
  • Research in structural biology is shedding light on how PI3K flexibility affects mutations, drug resistance, and the selective targeting of these enzymes in various diseases.

Article Abstract

The PI3K pathway is a communication hub coordinating critical cell functions including cell survival, cell growth, proliferation, motility and metabolism. Because PI3Kalpha harbors recurrent somatic mutations resulting in gains of function in human cancers, it has emerged as an important drug target for many types of solid tumors. Various PI3K isoforms are also being evaluated as potential therapeutic targets for inflammation, heart disease, and hematological malignancies. Structural biology is providing insights into the flexibility of the PI3Ks, and providing basis for understanding the effects of mutations, drug resistance and specificity.

Prostate cancer (PC) represents one of the leading causes of cancer-related morbidity and mortality in men, requiring further understanding to improve diagnosis and treatment. Germline BRCA1/2 mutations, primarily identified in other hereditary cancers, confer an increased risk of developing PC; thus, testing is essential to assess cancer risk, guiding preventive strategies and screening. Recently, somatic BRCA1/2 mutations have emerged as pivotal predictive biomarkers of responsiveness to the poly ADP-ribose polymerase (PARP) inhibitors.

Somatic and genetic mutations in glutathione peroxidases (GPxs), including GPx7 and GPx8, have been linked to intellectual disability, microcephaly, and various tumors. GPx7 and GPx8 evolved the latest among the GPx enzymes and are present in the endoplasmic reticulum. Although lacking a glutathione binding domain, GPx7 and GPx8 possess peroxidase activity that helps the body respond to cellular stress.

Recent studies have demonstrated the association between constitutional ring chromosome 21 (r(21)c) and the development of B-cell acute lymphoblastic leukemia (B-ALL) with intrachromosomal amplification of chromosome 21 (iAMP21). iAMP21 acts as a driver which is often accompanied by secondary alterations that influence disease progression. Here, we report an atypical case of iAMP21 B-ALL with a unique molecular profile in the context of r(21)c.

Apurinic/apyrimidinic (AP) sites are endogenous DNA lesions widespread in human cells. Having no nucleobases, they are noncoding and promutagenic. AP site repair is generally initiated through strand incision by AP endonuclease 1 (APE1).

Evolutionary dynamics of mitochondrial genomes and intracellular transfers among diploid and allopolyploid cotton species.

Shenzhen Branch, Guangdong Laboratory of Lingnan Modern Agriculture, Key Laboratory of Synthetic Biology, Ministry of Agriculture and Rural Affairs, Agricultural Genomics Institute at Shenzhen, Chinese Academy of Agricultural Sciences, Shenzhen, 518120, China.

Background: Plant mitochondrial genomes (mitogenomes) exhibit extensive structural variation yet extremely low nucleotide mutation rates, phenomena that remain only partially understood. The genus Gossypium, a globally important source of cotton, offers a wealth of long-read sequencing resources to explore mitogenome and plastome variation and dynamics accompanying the evolutionary divergence of its approximately 50 diploid and allopolyploid species.

Results: Here, we assembled 19 mitogenomes from Gossypium species, representing all genome groups (diploids A through G, K, and the allopolyploids AD) based on a uniformly applied strategy.
