- PMID 41986369 (2026, NPJ Regenerative medicine) — Heart ventricle regeneration in the lizard Eublepharis macularius, the leopard gecko.. Abstract (opening): Among mammals, injury to the heart typically results in scar formation and diminished cardiovascular function. In contrast, some teleost fish and salamanders can replace damaged heart tissue and restore overall function. For most species, however, less is known. Here, we investigate cardiac self-repair in an amniote capable of multi-tissue regeneration, the leopard gecko (Eublepharis macularius). To create a heart lesion, we placed a liquid nitrogen-cooled metal probe directly onto the ventricle. The result was a cryoinjury to ~20% of the ventricle. Cardiac cryoinjury induced localized cardiac cell death, followed by an increase in cell proliferation by injury-adjacent cardiomyocytes and non-cardiomyocytes. By 100 days, the histology of the ventricular myocardium was nearly completely restored. Echocardiography and invasive hemodynamic monitoring demonstrated that global cardiac function is restored within this timeframe, verifying functional replacement of the myocardium. To explore the molecular basis, we performed bulk RNA sequencing of the injury-adjacent tissue and found that many of the molecular mechanisms common to other cardiac regenerating species, including genes involved in heart development, glycolysis, and extracellular matrix deposition, are also conserved in geckos. Taken together, this work expands the comparative framework of heart regeneration to include reptiles and indicates that the ability to replace missing or damaged cardiomyocytes is shared across >50 million years of evolution. *[CC BY — Open Access, verbatim with attribution.]*

- PMID 41730629 (2026, The Journal of veterinary medical science) — Localized oral histiocytic sarcoma in a leopard gecko (Eublepharis macularius).. Abstract (opening): A two-year-old female leopard gecko presented with a mass in the oral cavity with apparent exophthalmos. Despite medical management, the animal died. Grossly, the firm and tan to white mass extended from the oropharyngeal region to the external surface overlying the cornea of the left eye. Histologically, the mass was a poorly-demarcated, densely cellular, invasive neoplasm. The neoplasm was composed of solid sheets and interlacing bundles of round, polygonal, and short spindle-shaped cells. Immunohistochemically, the neoplastic cells were positive for Iba-1 and CD204. These findings were consistent with a localized histiocytic sarcoma. This is the first documentation of the gross, histopathological, and immunohistochemical features of localized histiocytic sarcoma in a leopard gecko. *[CC BY — Open Access, verbatim with attribution.]*

- PMID 41183498 (2026, Genetics) — Candidate genes underlying hypomelanistic morphs in squamate reptiles.. Abstract (opening): Skin coloration is crucial for the survival of animals and ranges from spectacular colorful displays used to attract a mate to cryptic camouflage used to avoid predators. Among the 3 main types of chromatophores, melanophores are the most widespread in vertebrates and can set the skin tone by the amount of melanin they produce and store in dedicated vesicles, the melanosomes. Mutations associated with melanophore differentiation and maturation result in hypomelanistic and amelanistic phenotypes, both extensively studied in mammals but less so in snakes and lizards. Here, we characterize at the genomic, transcriptomic, and histological level, the Hypomelanistic corn snake morph and 3 hypomelanistic leopard gecko morphs. To minimize bias in studying leopard gecko color morphs, we first assembled a chromosome-level genome from a wild-type individual in terms of coloration. We propose that candidate mutations in 3 melanogenesis factors generate these phenotypes: (i) tyrosinase (TYR), an essential enzyme for melanin synthesis, (ii) NCKX5 (SLC24A5), an ion exchanger involved in melanosome maturation, and (iii) the P protein (OCA2), a transmembrane transporter for tyrosine. Our extended bulk RNA sequencing analyses show that additional pigmentation-related genes, affecting melanin production, melanosome motility, and melanophore migration, are dysregulated in the embryonic skin of the mutated animals. This observation highlights the likely associations among the corresponding pathways and is in line with our electron microscopy imaging results. Indeed, the subcellular structure of melanophores is uniquely altered at each of the 4 morphs and likely reflects a multigenic effect. These findings demonstrate that conserved pigmentation genes can produce species-specific effects, underscoring the modular nature of skin coloration in vertebrates. Our work establishes reptiles as comparative models for studying pigment cell biology and reveals evolutionary flexibility in the genetic regulation of melanogenesis. *[CC BY — Open Access, verbatim with attribution.]*

- PMID 42449365 (2026, BMC biology) — *[Paraphrased derived summary — non-Open-Access source.]* Lemon-frost leopard geckos (Eublepharis macularius) show >80% prevalence of iridophoroma, pigment-cell tumors that can recur and metastasize; whole-genome sequencing of matched tumor/normal samples found a shared TBP missense mutation and a recurrent IARS1–RNF213 gene fusion across tumors, with dysregulated actin filament organization (comparative oncology; source excerpt truncated).
