Breast cancer represents the primary cause of death of women under 65 in developed countries, due to the acquisition of multiple drug resistance mechanisms. The PI3K/AKT pathway is one of the major regulating mechanisms altered during the development of endocrine resistance and inhibition of steps in this signalling pathway are adopted as a key strategy to overcome this issue. ADP-ribosylation is a post-translational modification catalysed by PARP enzymes that regulates essential cellular processes, often altered in diseases.

T-cell prolymphocytic leukemia (T-PLL) is a rare mature T-cell lymphoma that is usually associated with poor prognosis and short overall survival. We present a case of a 61-year-old woman presenting with T-PLL and the leukemic cells harboring (-breakpoint cluster region; -ABL protooncogene 1) fusion transcripts as the result of a variant of t(9;22)(q34;q11) called Philadelphia translocation: t(9;22;18)(q34;q11;q21). Sequencing revealed a rare transcript with an exon 6 breakpoint corresponding to e6a2 transcripts, which has thus far been reported in only 26 cases of leukemias.

BCR::ABL1-like B-lymphoblastic leukaemia (B-ALL) neoplasms lack the BCR::ABL1 translocation but have a gene expression profile like BCR::ABL1 positive B-ALL. This includes alterations in cytokine receptors and signalling genes, such as and Cases with CRLF2 rearrangements account for approximately 50% of cases of Philadelphia-like acute lymphoblastic leukaemia (Ph-like ALL), and the frequency of specific genomic lesions varies with ethnicity such that IGH::CRLF2 translocations are more common in Hispanics and Native Americans.We report two cases of BCR::ABL1-like ALL, with significant eosinophilia.

Neuroinflammation, a significant contributor to various neurodegenerative diseases, is strongly associated with the aging process; however, to date, no efficacious treatments for neuroinflammation have been developed. In aged mouse brains, the number of infiltrating immune cells increases, and the key transcription factor associated with increased chemokine levels is nuclear factor kappa B (NF-κB). Exosomes are potent therapeutics or drug delivery vehicles for various materials, including proteins and regulatory genes, to target cells.

Background: The use of intrauterine devices (IUDs) for contraception has increased in many countries. However, their application has some serious complications such as uterine perforation and injury to adjacent organs. The translocated IUD into the bladder is a very rare occurrence.
