1. A method of detecting and diagnosing gastric cancer in a patient in need thereof, comprising the steps of:
- obtaining a biological sample comprising whole blood from said patient;
analysing said biological sample for the expression of MH15 (also known as Hn1L), said analysing step comprising detecting mRNA encoded by the polynucleotide sequence set forth in SEQ ID NO;
1 in peripheral blood mononuclear cells (PBMCs) from the biological sample; and
wherein expression of said mRNA in said PBMCs at levels in excess of the level of mRNA encoded by the polynucleotide sequence set forth in SEQ ID NO;
1 in PBMCs from a normal, healthy subject indicates that said patient has gastric cancer.

Abstract
MH15 (Hn1L) is identified as an oncogene. Methods and compositions for detecting and diagnosing cancer in patients are provided, by determining the level of MH15 expression in biological samples. Also provided are methods for screening for inhibitors and moderators of MH15 expression and activity, as well as compositions comprising compounds and molecules that inhibit or moderate MH15 expression or activity, thereby treating cancer, in vivo.

2. A method of detecting and diagnosing gastric cancer in a patient in need thereof, comprising the steps of:
-
(a) providing a biological sample comprising whole blood from said patient; (b) detecting the level of MH15 (also known as Hn1L) mRNA encoded by the polynucleotide sequence set forth in SEQ ID NO;
1 in peripheral blood mononuclear cells (PBMCs) from the biological sample; and(c) comparing the level of MH15 mRNA in the biological sample with the level of MH15 mRNA encoded by the polynucleotide sequence set forth in SEQ ID NO;
1 in a control sample of PBMCs from from a normal, healthy subject;wherein an increased level of said MH15 mRNA in the biological sample compared to said MH15 mRNA in the control sample indicates the presence of gastric cancer in said patient. - View Dependent Claims (3)

5. An in vitro method for monitoring the recurrence of gastric cancer in a patient who has been treated for cancer, comprising the steps of:
-
(a) interacting a biological sample comprising whole blood from the patient with a substance selected from polynucleotides, probes or primers that interact with MH 15 (also known as Hn1L) mRNA encoded by the polynucleotide sequence set forth in SEQ ID NO;
1;(b) detecting the level of MH15 mRNA of SEQ ID NO;
1 that interacts with the substance in peripheral blood mononuclear cells (PBMCs) from the biological sample;(c) repeating steps (a) and (b) using a biological sample comprising whole blood from said patient at a subsequent point of time; and (d) comparing the level of said MH15 mRNA detected in step (c) with the level of MH15 mRNA encoded by the polynucleotide sequence set forth in SEQ ID NO;
1 detected in a control sample of PBMCs from a normal, healthy subject and therefrom determining the recurrence of gastric cancer in said patient,wherein a level of said mRNA detected in said biological sample in step (c) in excess of the level of said MH15 mRNA detected in the control sample is indicative of a recurrence of the gastric cancer in the patient.
