While the genetic paradigm of cancer etiology has proven powerful, it remains incomplete as evidenced by the widening spectrum of non-cancer cell-autonomous "hallmarks" of cancer. Studies have demonstrated the commonplace presence of high oncogenic mutational burdens in homeostatically-stable epithelia. Hence, the presence of driver mutations alone does not result in cancer.

We present the case of a 42-year-old Indian male with prurigo nodularis, exhibiting multiple verrucous, brownish-black nodules on the left lower and right upper extremities, with milder involvement of the right lower extremity. The lesions were asymmetrically distributed in a near-linear pattern, with prominent white hyperkeratosis and associated moderate pruritus and paresthesia. Differential diagnoses included pemphigoid nodularis, verruca vulgaris, and hypertrophic lichen planus, with a biopsy confirming prurigo nodularis.

Triticum mosaic virus (TriMV; Poacevirus tritici) is the founding member of the genus Poacevirus within the family Potyviridae. TriMV is one of the components of the wheat streak mosaic disease (WSMD) complex, an economically significant wheat disease in the Great Plains region of the USA. TriMV contains a single-stranded positive-sense RNA genome of 10,266 nts with an unusually long 5'-nontranslated region of 739 nts.

Shrews are among the most speciose of mammalian clades, but their evolutionary history is poorly understood. Their fossil record is fragmentary and even the anatomy of living groups is not well documented. Here, we incorporate the oldest, most complete fossil shrew yet known into the first phylogenetic analysis of the group to include molecular, morphological and temporal data.

X-linked hypophosphatemic rickets (XLH), the most common form of hereditary rickets, is characterized by renal phosphate wasting and abnormal vitamin D metabolism due to elevated circulating levels of the phosphatonin fibroblast growth factor 23 (FGF23). Dominant inactivating variants of the phosphate regulating endopeptidase homolog, X-linked (), gene are present in patients with XLH, and more than half of affected patients carry de novo variants. We report on 3 families in whom affected members had highly unusual pathogenic variants.
