Expression and Sequence of Calcium Channels in Non-small Cell Lung Carcinoma (NSCLC)
An observational study of NSCLC, run by Hadassah Medical Organization.
Trial summary
Calcium is an extremely important ion used in our body for many processes. One of its tasks is to control gene expression. Cells intake calcium from their surroundings though special calcium channels located on the surface membranes of the cells. Read more about this study

About this study
Calcium is an extremely important ion used in our body for many processes. One of its tasks is to control gene expression. Cells intake calcium from their surroundings though special calcium channels located on the surface membranes of the cells.
The great many studies on such calcium channels were performed on excitable cells such as muscle, heart or neuronal cells, where the calcium ions are controlled by voltage. Surprisingly, not much is known about the identity of calcium subunits in non-excitable cells like epithelial cells (which compose most of the connective tissue in the body), liver cells, lung cells, immune system cells, etc.

Recently, the investigators have shown that calcium channels from muscles are, in fact, expressed in T cells of the immune system, where they are used for proliferation. The investigators postulated that probably other cell types, especially cancerous cell types, might be using these subunits similarly.
The aim of this study is to determine the identity and sequence of calcium subunits expressed in non-small cell Lung Carcinoma (NSCLC), which accounts for 80% of the worldwide lung cancer deaths.
Read the detailed description
Initial examination of NSCLC cell lines determined that they express the mRNA of voltage gated calcium subunits, found normally in neurons. Furthermore sequence analysis of these subunits has shown that modifications have occurred.
The aim of the study in NSCLC patients is to sequence and clone the calcium channel subunits expressed in their tumor. Expression and Sequence will be compared between the normal and cancerous lung tissue for each patient.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
A biopsy sampleOther
Sample tissue will be obtained from the routine biopsy taken for pathological evaluation. A pathologist will determine which part of the tissue will be forwarded for this study, to avoid any interference with the pathological evaluation.
| Study group | Role | What they receive |
|---|---|---|
| NSCLC Patients | Sample biopsies from normal and cancerous lung tissue. Receives: Other: A biopsy sample | |
| Patients without NSCLC | Sample biopsies from normal lung tissue.Control group. Receives: Other: A biopsy sample |
What is being measured
The primary outcome is the main question the study is designed to answer.
mRNA expression and sequence of calcium channel subunits in NSCLC
mRNA will be extracted from each sample biopsy followed by real time PCR analysis. If any calcium subunit is detected, semi quantitative PCR will be performed, PCR bands will be cloned and sequenced.
Measured: up to 1 month per patient

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
mRNA expression and sequence of calcium channel subunits in NSCLC (time frame: up to 1 month per patient). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Aug 2015; AzTrials last refreshed its copy on 6 Nov 2026.
