Hücre İçi Kalsiyum Sinyali, Apoptoz ve Kanser Progresyonunda Kalsiyum Kanallarının (Voc, Trp ve Soc Kanalları) Rolü

Öz

Intracellular calcium signaling is associated with cardiovascular and neurological diseases and many other diseases. Altered expression of calcium influx channels is associated with various types of cancer including breast, colon, prostate, ovary, brain. While important for regulating many normal, cellular processes, increases in intracellular Ca+2 have been implicated in a variety of processes associated with tumour progression, including breast cancer cell migration and proliferation. Studies comparing cancer tissues with noncancerous tissues have revealed changes in calcium signaling mediated by some members of the calcium channel family (voc, trp and soc channels). As we pointed out, altered expression of calcium channels plays a role in cancer progression. This review focuses on the recent studies regarding the differences in protein expression of calcium channels found in plasma membrane of cancer cells.

Hücre İçi Kalsiyum Sinyali, Apoptoz ve Kanser Progresyonunda Kalsiyum Kanallarının (Voc, Trp ve Soc Kanalları) Rolü

Öz

Hücre içi Ca⁺² sinyali kardiyovasküler ve nörolojik hastalıklarla ve daha pek çok hastalıkla ilişkilidir. Ca⁺² giriş kanallarının değişmiş ekspresyonları da meme, kolon, prostat, over, beyin gibi çeşitli kanser tipleri ile ilişkilendirilmektedir. Hücre içi Ca⁺² artışları pek çok hücresel proseste önemli iken, kanserli bir olguda hücre proliferasyonu ve migrasyonu dahil olmak üzere tümör progresyonu ile ilişkili olan pek çok proses için de önemli ve etkilidir. Kanser ve kanser kökenli olmayan hücreleri karşılaştıran çalışmalar, kalsiyum kanal ailesinin (Voc, Trp ve Soc kanalları) bazı üyelerinin aracılık ettiği Ca⁺²-aracılı değişiklikleri ortaya koymaktadır. Kanser progresyonunda kalsiyum kanallarının değişmiş ekspresyonunun rol oynadığı dikkat çekmektedir. Bu derlemede kanser hücrelerinin plazma zarında bulunan kalsiyum kanallarının protein ekspresyonlarındaki değişiklikler ve sonuçları son yapılan çalışmalarla ifade edilmektedir.
