Özet:

 This study aims to investigate the expression patterns of Galectin-1 Gal-1 and Gal-3 in the testis and epididymis of Anatolian ground squirrel Spermophilus xanthoprymnus during nonbreeding pre-hibernation and hibernation periods. Hibernation is a physiological state characterized by a reduction in metabolic rate and body temperature. Gal-1 and -3 are implicated in many biological functions. Twelve squirrels were used in this study. Followed by routine tissue processing, tissue samples underwent immunohistochemical procedure. Histological examination and statistical analysis were performed. Immunohistochemical investigation revealed that Gal-1 expression during pre-hibernation was confined to peritubular myoid cells and vascular smooth muscle cells, with no expression observed in Sertoli or spermatogenic cells. Gal-1 in the epididymis was localized to smooth muscle cells encircling the epithelium and within blood vessel walls, exhibiting markedly elevated expression across the caput, corpus, and cauda regions. During hibernation, testicular and epidydimal Gal-1 expression exhibited a considerable reduction. During pre-hibernation, Gal-3 exhibited a unique pattern, with expression noted in the seminiferous epithelium and Leydig cells. Gal-3 was detected in the epithelial cells throughout the epididymis, with greater intensity in specific epithelial cells. During hibernation, Gal-3 expression increased in Sertoli cells, spermatogonia, and spermatocytes within the testis, while exhibiting diminished intensity in the epididymal epithelium across all regions. The findings suggest that Gal-1 and -3 may be involved in seasonal reproductive adaptability during nonbreeding pre-hibernation and hibernation. Further research could clarify their specific molecular functions in hibernating species.

 Bu çalışma, üreme dışı aktif ve hibernasyon dönemlerinde Anadolu yer sincabı Spermophilus xanthoprymnus testis ve epididimisinde Galectin-1 Gal-1 ve Gal-3 ekspresyonunu araştırmayı amaçlamaktadır. Hibernasyon, metabolik hız ve vücut sıcaklığındaki azalma ile karakterize fizyolojik bir durumdur. Gal-1 ve Gal-3 birçok biyolojik fonksiyonda rol oynamaktadır. Bu çalışmada on iki sincap kullanılmıştır. Rutin doku işleme tabi tutulduktan sonra, doku örnekleri immünohistokimyasal prosedüre tabi tutuldu. İnceleme ve istatistiksel analiz yapıldı. İmmünohistokimyasal inceleme, aktif dönemde Gal-1 ekspresyonunun peritübüler miyoid hücreler ve vasküler düz kas hücreleriyle sınırlı olduğunu, Sertoli veya spermatogenik hücrelerde ekspresyon gözlemlenmediğini ortaya koymuştur. Epididimisde Gal-1, epiteli çevreleyen düz kas hücrelerinde ve kan damarı duvarlarında lokalize olmuş, kaput, korpus ve kauda bölgelerinde belirgin şekilde yüksek ekspresyon sergilemiştir. Kış uykusu sırasında testis ve epididimal Gal-1 ekspresyonunda önemli bir azalma gözlenmiştir. Aktif dönemde Gal-3 kendine has bir ekspresyon göstermiş olup seminifer epitel ve Leydig hücrelerinde gözlemlenmiştir. Gal-3, epididimis boyunca epitel hücrelerinde tespit edilmiş, belirli epitel hücrelerinde daha yoğun olarak bulunmuştur. Kış uykusu sırasında Gal-3 ekspresyonu testisteki Sertoli hücrelerinde, spermatogonyumlarda ve spermatositlerde artarken, tüm bölgelerde epididimal epitelde yoğunluk azalmıştır. Bulgular, Gal-1 ve Gal-3ün üreme dışı ön kış uykusu ve kış uykusu sırasında mevsimsel üreme adaptasyonunda rol oynayabileceğini göstermektedir. Kış uykusuna yatan türlerde spesifik moleküler işlevlerini açıklığa kavuşturmak için daha fazla çalışmaya ihtiyaç duyulmaktadır.
