Clinical Characteristics, Cytogenetic Risks, and Prognoses of Young Multiple Myeloma Patients in the Era of Novel Therapies.

In recent years, there have been significant advances in the understanding and treatment of multiple myeloma (MM). Despite this progress, there is still limited information on the disease in patients aged 50 or younger, including the impact of young age on disease characteristics, treatment, and outcome. In this retrospective study, we analyzed 68 newly diagnosed MM patients aged ≤ 50 years (y) who had undergone at least one peripheral blood stem cell transplantation (PBSCT).

Digest: Habitat associations shape a hybrid zone in killifish.

Hybrid zones provide valuable opportunities to interrogate the processes that drive speciation. In a new study, Hardy et al. (2024) demonstrate that the dominant vegetation type in patchy cordgrass salt marshes and mangrove swamps drives a mosaic hybrid zone between two species of killifish.

Rearrangements of viral and human genomes at human papillomavirus integration events and their allele-specific impacts on cancer genome regulation.

Human papillomavirus (HPV) integration has been implicated in transforming HPV infection into cancer. To resolve genome dysregulation associated with HPV integration, we performed Oxford Nanopore long-read sequencing on 72 cervical cancer genomes from an Ugandan dataset that was previously characterized using short-read sequencing. We found recurrent structural rearrangement patterns at HPV integration events, which we categorized as: del(etion)-like, dup(lication)-like, translocation, multibreakpoint, or repeat region integrations.

Temperature affects conspecific and heterospecific mating rates in .

Behavioral mating choices and mating success are important factors in the development of reproductive isolation during speciation. Environmental conditions, especially temperature, can affect these key traits. Environmental conditions can vary across, and frequently delimit species' geographic ranges.

Immunohistochemistry in the Differential Diagnosis of Triple Negative Breast Carcinoma and High-grade Serous Carcinoma: Old and New Markers.

Distinction of metastasis to the breast from a breast primary, particularly high-grade triple-negative breast cancer (TNBC), can be challenging due to nonspecific morphology and immunohistochemical (IHC) profiles. Among metastases to the breast, high-grade serous carcinoma (HGSC) of müllerian origin is most likely to be misdiagnosed as TNBC. We assessed breast and müllerian markers on TNBC and HGSC, including keratin 7, keratin 20, GATA3, GCDFP15, mammaglobin, p53, PAX8 (MRQ50 and BC12 clones), TRPS1, SOX10, and WT1.
